Sunday Morning Bird Walks
The weekly Sunday morning
bird walks are held every Sunday morning, all year. Meet at 8 a.m. in the south
parking lot of the Belle Haven picnic area. Walks are led by experienced birders and all are welcome.
The most
recent reports are found at the top of the page; be
sure to scroll through the reports to view the earlier sightings.
Sightings
Seven birders joined me and Larry Meade for the weekly Sunday morning bird walk
at Dyke Marsh on the Potomac River in Alexandria. Noticeable evidence of
fall migration was the presence of only 2 Osprey and only one Swallow, a
single Northern Rough-winged, plus no Vireo species. 3 warbler species
spotted were B&W, Chestnut-sided, and Yellow. The 2 American Coots which
have been seen regularly were still present. A Least Flycatcher also
afforded good views. Great Egrets were abundant, with 57 counted just from
the picnic area at the beginning of the walk (tide was still pretty low).
Good news for those concerned about the lack of House Sparrows at the
marina; we saw 8 this morning. Not satisfied to be 1 bird short of 50
species, Larry & I went back to the river after compiling the list to find a
Pie-billed Grebe and a Great Black-backed Gull to bring the day's total to
51.
Many thanks also to Larry for identifying most of the butterflies and flying
insects we encountered. The highlight of that part of the morning was a
large black & yellow garden spider catching and eating a butterfly. Photos
available as soon as I post them to my Flickr account at
http://www.flickr.com/photos/28499865 AT N07/ in a short while.
The Sunday morning walks are sponsored by the Friends of Dyke Marsh and
occur weekly at 8:00 a.m., meeting in the vicinity of the south parking lot.

Nearly a dozen birders joined me for the walk at Dyke Marsh walk today. The
walk began with overcast skies and ended with a heavy drizzle. Despite the
wet conditions, the walk provided some interesting observations. Overall
numbers were low, with only a handful of representatives of many species,
but diversity was good for this time of year. Shorebirds are moving
through, with nice views of a Black-bellied Plover on the mudflats as seen
from the picnic area. Kurt Gaskill noted Short-billed Dowitchers and peeps
from his vantage point at the Stone Bridge. A young Cooper's Hawk, with
less than perfect hunting skills, provided great entertainment. The
Cooper's entered the picnic area and was immediately attacked by a Fish
Crow. The Cooper's relocated and went after several cardinals. No luck. It
pursued several other birds. No luck. Then the hawk went after a squirrel.
The squirrel stood its ground and then chased the hawk. The hawk briefly
chased another squirrel. The squirrel chased the hawk. Back and forth for a
good 5 minutes with the pursuer becoming the pursued. The end result was a
defeated hawk departing the area with no meal.
We found good numbers of Caspian and Forster's Tern. Two Mallard hens had
young in tow with one brood only half grown. Spots of avian activity along
the Haul Road were interspaced with quiet areas. The peninsula produced an
accommodating empid that we tentatively identified as a Willow until its
"whit" call secured its identity. A leucistic Northern Mockingbird,
sporting a mostly white head and pale markings displacing the gray areas,
was perched on the boardwalk. Notable misses included Marsh Wren. And what
happened to the House Sparrows? Last week there were none; today only one.
Not that we miss them.

The regular Field Trip to Dyke Marsh, sponsored by the Friends of Dyke Marsh
and open to all, had a wonderful morning seeing migrants and locals alike,
many in good numbers. We began on a somewhat cool morning (relatively
speaking, I think the temp was about 75F) with moderate humidity under blue
skies and puffy white clouds in the picnic area on the edge of the Potomac
R. We noted fine numbers of southbound Northern Rough-winged Swallows and
Barn Swallows. The barge out in the river was a collection point for terns
- mostly juvie Caspians Terns waiting to be fed! Nearby were a small group
of DC Cormorants and one Ruddy Duck (I believe this bird was reported
earlier this summer). A few Lesser Yellowlegs walked on the SAV eating this
and that. The Osprey were out and about, the young of the year learning how
to feed themselves. Great Egret numbers were fine - 28 - but down about
half from their roosting strength (they roost on the wooden dock pilings at
the mouth of Hunting Cr). Curiously, no Snowys were mixed in!
The picnic area produced a family groups of Orchard Orioles and Eastern
Kingbirds; a few Blue-gray Gnatcatchers hung around, too. Great looks at
the orioles as they fed in the ragweed and vines on the southern boundary of
the area. The marina produced the 2 American Coots that have summered at
Dyke, mixed in with dozens of Mallards. A Belted Kingfisher was perched on
a snag on the edge of the lagoon and a Pileated Woodpecker worked a snag
along Ramp Rd. Our walk down Haul Rd began with 2 Prothonotary Warblers
near the beginning (thanks Ellie!).
The boardwalk at the end of the trail gave us more Eastern Kingbird views,
Indigo Bunting, and a few Yellow Warblers. The swallow action never abated
and at least 2 Tree Swallows joined in. Ruby-throated Hummingbirds were a
delight for a Florida visitor with us today (and everyone else, too). We
finally saw 2 different 2nd year Bald Eagles flying over the woods. And we
noted a beautiful Red-shouldered Hawk fly over the lagoon and circle the
island. A flyby peep never stopped. Fortunately, the Spotted Sandpiper that
came by next did perch on a log. We added two different vultures at the
end. We ended the day at 56 species, listed below.

Five birders joined us this morning for the weekly Dyke Marsh birding tour.
This walk is held every Sunday of the year, except during Christmas Bird
Counts; it meets at 8:00 at the picnic area, and all are welcome. We were
barred by police from both the marina and Haul Road because of the ongoing
search for the kayaker missing from the area since July 31. We spent more
time than usual in the picnic area, especially the north portion. We then
strolled up to Hunting Creek, where we added 10 Least, 1 Semipalmated, 1
Spotted Sandpiper, 6 Kildeer, 4 Greater and 4 Lesser Yellowlegs, 1 Belted
Kingfisher, and a Downy Woodpecker The highlight of the trip was tolerably
cool weather.

Wasn't too too awful hot but wound up warming up pretty quickly, and
four people wound up finding their way to the riverside for todays
event - always on Sunday, 8am and always free and open to anyone and
everyone. Best bird of the day was an Imm. Red-bellied WP as it was a
life bird for one guest visiting from Utah and the only one to show
itself today, despite hearing others. We had a pretty good Woodpecker
day with Downy, Flicker, RB and an unusual visit by two Pileateds near
the Marina. Thirty or so Great Egrets matched the thirty or so GB
Herons working the bay off the picnic area. Mallard ducklings are
still evident -we saw three different broods - one brood still very
small. GC Flycatchers were cavorting in the locust trees at the Marina
and we watched a female Goldfinch putting the finishing touches on a
nest right over the path just north of Dead Beaver Beach. Cardinal
families were scooting around and an imm. Kingbird sat in the shade
waiting for mom or dad to feed it. No Terns of any shape or form
today. We managed to eke out 45 species on another warm July day -
stay cool and watch out for aftershocks!

The regular Field Trip to Dyke Marsh, sponsored by the Friends of
Dyke Marsh and open to all comers each Sunday at 8 am had a limited turn out
today; perhaps due to the hot weather, perhaps due to Father's Day. Yet,
for those who attended, it was a pretty good June day. The highlight was an
American Coot off the picnic area - it's been a while since we had a summering
coot at Dyke, my notes list 2003 as the last event. Another highlight was
finding a single Eastern Towhee still sporting juvie plumage - the little
fellow must have fledged from nearby in the last 3-4 weeks.
We started off at the picnic area and found only Mallards and Canada
Geese (lots of the latter!). A single male Wood Duck was mixed in with the
geese. Many Osprey and a Bald Eagle - recently fledged it seems given its
overall dark appearance. Lots of Orchard Orioles were about but no
Baltimore's were noted today. A Prothonotary called from the woods next to Ramp
Rd, Yellow Warblers at trails end, and Marsh Wren calling from the cattails at
the end, too. The list of 45 species is below.

The weekly walk was somewhat quiet today. We did manage to see
or hear 38 species. Highlights included a singing Indigo Bunting in the
parking area, a couple of Bald Eagles perched out in the river, singing
Yellow Warblers and some Marsh Wrens heard in the marsh from the
platform at the end of the boardwalk.

We had 8 people join us on the weekly Dyke Marsh walk. The
weather was warm and clear and nesting activity was in full swing.
We found Orchard Orioles and Blue-gray Gnatchatchers feeding
young at nests. But, the best find of nesting species was the Cedar
Waxwing we found sitting on a nest. We put a scope on the nest
and most of the group was able to get good looks at the bird sitting
on the nest, getting up, moving around, etc. We would be curious to find out it this species has ever been found
nesting here.

Larry Cartwright led the regular Sunday morning Field Trip to Dyke
Marsh, sponsored by the Friends of Dyke Marsh and open to the public.
Only a few people showed up for an amazing spring spectacle - Blackpoll
Warblers were EVERYWHERE (yes, even flying over the little bays). Truly an
abundant species today with 65 tallied, often in groups of 5 and 4. The balance
of the warblers were OK diversity-wise but the group was pleased with
the Black-throated Blues and American Redstarts and the Yellow
Warblers were in better than average numbers. We started out looking over a mixed
warbler/vireo flock in the picnic area as a Red-tailed Hawk had caught
a rabbit early in the morning and the local and migrant passerines were
very much into mobbing the scene. Swainson's Thrush were in good song
in several places and a Veery popped up and fed in the berry tree near the
beginning of Haul Rd. The Osprey put on the usual great show, a single adult
Bald Eagle held forth on the mudflats despite the rising tide, and we finally
notched a few Laughing Gulls near the end of the trip as the birds headed south
down the Potomac. Unexpected! Cedar Waxwings were in very good
numbers today making the top 5 in numbers with a tally of 50 from several flocks.
Swallow numbers are down suggesting the bulk of the swallows have moved
through the area and the remainders are mainly local breeders. We also heard
and briefly saw a Marsh Wren on the island across from the boardwalk
terminus. One participant dug out a very wonderfully colored Orange-variant
Scarlet Tanager. Orioles were often heard but were mainly seen near the end
of the trip so it was a bit hard to pin down their numbers, but we suspected
that mainly breeders remained. Lastly, Warbling Vireos seem to have
made a good push as the picnic area and marina finally had singers. The regular
Field Trip netted 63 species. Visits to the Stone Bridge early and late in
the day added 13 more species including shorebirds, American Black
Duck, Greater Black-backed Gull, Northern Rough-winged Swallow and Northern
Waterthrush.

Kurt Gaskill reported finding a Canada Warbler between the marina
and Haul Road, but it was not apparent when our group went through that area.
Also, a brief stop at the stone bridge at ~ 7:00 am yielded 12
Semipalmated Sandpipers, 3 Wood Ducks, and a Spotted Sandpiper.
Kurt's posted his findings on the nearby bike trail a few minutes ago.

The skies began mostly clear with little wind for today's field trip,
which was sponsored in combination with the Audubon Naturalist
Society and the Friends of Dyke Marsh. About 10 people joined the
trip which got off to a great start viewing an American White Pelican
floating in the Potomac off the picnic area. It started off near the
Osprey nest in the bay and then swam over to a group of DC
Cormorants on a snag near the barge with the cranes. We left it at 9
am and I was unable to relocate it later at about 1130.
Also, I noted the crane boom on the barge was lowered and the
Osprey nest was needlessly destroyed. As I am sure you know, the
nest was protected under federal law.
Other highlights of our field trip was the arrival of the first Baltimore
Oriole which we spotted in the picnic area. Over the river scored of
swallows flew - most appeared to be Tree, but a good number were
Northern Rough-winged with a few Barn thrown in for good measure.
We also noted a wonderful adult male Purple Martin. Waterfowl is
getting hard to find but fortunately 2 Common Mergansers came by
along with a female Hooded Merganser. Five Gadwall set down in the
bay off the picnic area, we noted distant Lesser Scaup, a few close
by Mallards, and a single male Wood Duck in the lagoon near the
marina. Near the marina was also a single American Coot.
Overflying were two groups of Common Loons totaling 12.
The dozen plus Osprey were up to the usual high-jinks to the delight
of all; the FODM currently believe there are 10 nests in the Dyke
Marsh area. An adult Bald Eagle paid a visit to the mudflats, sending
nearly 3 dozen Caspian Terns up in to the air along with Ring-billed
and Herring Gulls; joining the mix were 2 Boneparte's Gulls. The
skies then clouded over and the wind picked up - it was downright
chilly! Starting down Haul Rd brought us face-to-face, sort of
speaking, with a Yellow-throated Warbler (probably the same bird as
reported yesterday). A couple of Eastern Towhees called from the
bushes as well as several White-throated Sparrows. Swamp
Sparrows were singing from the marsh and one pished up easily.
Along the dogleg we spotted a male Belted Kingfisher, 3 Spotted
Sandpipers flew from the island past us, and a Greater Yellowlegs
called from the marsh. As we turned to go, an adult Red-tailed Hawk
circled over the picnic area and a Forster's Tern called for our
attention. On the way back to the cars, a large group of Chimney
Swifts flew overhead. We tallied 57 species.
Next week there will be a marathon on the GW Parkway which
means traffic will be interrupted for the first part of the morning. So
either arrive early at the picnic area parking lot or park across the
street near the apartments. Thanks!

The regular Sunday morning field trip to Dyke Marsh, sponsored by
the Friends of Dyke Marsh for more than 18 yrs (meet at 8am), was
met with delightful blue skies and cool to warming temperatures. The
group of 8 were treated to a northbound Merlin over the marina early
into the walk. Viewing the Potomac we spotted a small group of
Lesser Scaup, Caspian Terns flying this way and that, and many fine
breeding-plumaged DC Cormorants. The Osprey were the usual
delight to watch, fishing and carrying fish and sticks. A single
American Coot was in the marina lagoon. Down Haul Rd it seemed
like Tufted Titmice, Carolina Wrens, and Am. Goldfinch were singing
everywhere! We found a few Blue-gray Gnatcatchers - including one
working on a nest. A few Yellow-rumps were about, 2 were singing.
Overflying Laughing Gulls were spotted. Brown Thrasher and Swamp
Sparrow singing at the dogleg, a couple of Eastern Towhees, several
Song Sparrows and the usual Brown-headed Cowbirds nearly rounded
out the day. Yet, at the end of the boardwalk we spied 3 Common
Mergansers, a Greater Yellowlegs and an adult Bald Eagle flew over.
And one of the birders noted some Northern Shovelers early in the
morning putting down near the marina.
After the field trip, I visited the Stone Bridge, saw a pair of Wood
Ducks, found the Northern Shovelers and counted gulls and Caspian
Terns. Today's results of 48 species are listed below. What will next
Sunday bring? -- Kurt Gaskill.

Eleven birders joined me for the Easter edition of the Sunday morning
Dyke Marsh bird walk, sponsored by the Friends of Dyke Marsh and
open to all. Highlights included a briefly seen, but singing
Yellow-throated Warbler (not often observed at this location), a Palm
Warbler at the end of the Haul Road peninsula, Caspian Terns, highly
vocal Laughing Gulls on the move, many singing Ruby-crowned
Kinglets, and a Brown Thrasher. The breeding season for common
resident species is in full swing, with a Mourning Dove on nest, and
nest building by Northern Cardinals and Carolina Wrens. We saw 4
active Osprey nests; many of the rootball nests from last year appear
abandoned either because the foundation has been washed away,
leaving exposed roots, but no usable foundation, or the fallen over tree
itself is gone! Thanks to Rich Rieger for assisting with today's walk.

The weekly bird walk at Dyke Marsh, sponsored by the Friends of Dyke Marsh, was
attended by 7 folks this morning. The Potomac was very high and full of debris,
which may have been a reason for the very low waterfowl count. The gray, cool
weather may have also contributed to a relatively low overall count of 42
species. However, there were some notable sightings. Just after I arrived at
the parking lot I watched a young red-tail drop down in the picnic area and
catch a large rat. The hawk flew onto a low branch close to the parking lot,
giving the early arrivals for the walk great views of it enjoying the meal. A
young Cooper's hawk flew in and made a single pass at the feeding red-tail. We
saw a number of Bonaparte's gulls out in the middle of the river. In the
embayment south of the boardwalk we got great looks at a male redhead. A large
flock of tree swallows contained a single northern rough-winged swallow. We
also saw or heard 3 swamp sparrows. Osprey nest building is in full swing,
although some of last years nesting spots appear to have been washed away by
the winter's storms.

Nobody joined me for today's Dyke Marsh walk, perhaps due to local
flooding, so I did a little walkthrough by myself. Half of the Marina,
much of the wooded area, and Haul Road south of the overlook that
we refer to as Dead Beaver Beach were under water at high tide
(8:27AM in Alexandria). It was a decent day anyway. I was surprised
to find 4 American Pipits foraging beside a flooded depression along
the river in the picnic area. Pine Warblers are on the move. One was
observed in the company of Yellow-rumped Warblers along Haul
Road. Nest construction by the Marina Osprey pair seems to have
been temporarily suspended, perhaps due to the inclement weather.
A Greater Scaup was with a small group of Lessers as seen from
Dead Beaver Beach and a 2 Rusty Blackbirds were with Red-wings at
the same location. Despite the periodic drizzle, many birds were in
song, including 2 Winter Wrens. Big miss today was Great Blue
Heron. Water was just too deep.

VA Birders: Ten birders joined us on a gorgeous sunny snow
bank-melting morning for the weekly Dyke Marsh tour of the Belle
Haven picnic area and marina and a stroll down Haul Road. This walk
is held every Sunday of the year, except during Christmas Bird
Counts; it meets at 8:00 at the picnic area, and all are welcome.
The best bird Oscar was awarded to Common Loon, halfway into
breeding plumage, fishing off the marina, then flying off up-river.
Another nomination went to Fox Sparrow--not all that common on
Haul Road, in my experience--that gave all a nice view.

Overcast with just a hint of breeze and temps near 40F met today's
Dyke Marsh Field Trip, sponsored by the Friends of Dyke Marsh

meandering east and west across the state line in the
Potomac River. Also notable was a Gray Catbird vying for our
attention as we walked back to our cars. Really amazing how this

Fellow birders, Two persons joined me this morning for the weekly walk at Dyke Marsh in Alexandria, which is sponsored by The Friends of Dyke Marsh and starts at 8 each Sunday morning at the south end of the parking lot to the Belle Haven picnic area. Highlights included seeing four raptors perched
at relatively close range: Cooper's Hawk, Red-shouldered Hawk, Red-tailed Hawk and Bald Eagle, including two adults perched next to each other on what appeared to be a tire in the mud near Hunting Creek, Golden-crowned and Ruby-crowned Kinglets, 12 Great Blue Herons perched close to each other across from the platform viewing area at the end of Haul Road and two Great
Egrets (not counting another 7 seen by me in the marshy area across from Hunting Creek on the way to the walk). Other highlights included 8 species of waterfowl, many Yellow-rumped Warblers and a Gray Catbird that was heard calling by all trip participants as we walked back along Haul Road.

Ten birders joined me for the Dyke Marsh Sunday morning bird
walk, sponsored by the Friends of Dyke Marsh and open to everyone free of charge.
There was a nice assortment of diving ducks in the river at fairly low tide, but most
people were impressed by the Tundra Swans, a species rarely seen in
large numbers at Dyke. No raptors were observed except for 7 Bald Eagles, 6 of
these possiblty establishing pair bonds. The stroll down Haul Road yielded a
cooperative Ruby-crowned Kinglet and 2 Winter Wrens. Finally, 7 Eastern
Bluebirds awaited us as we made our way down to the end of the boardwalk. A

There were mostly the usual suspects at Dyke Marsh this morning.
It was the weekly walk held every Sunday at 8:00 and sponsored by
The Friends of Dyke Marsh and open to all. What was probably the
best bird of the day was in the picnic area right at the beginning of
the walk. I pished a bit, and a nice Fox Sparrow popped out of the

The ten birders who joined me for this week's edition of the Dyke Marsh Sunday
morning walk experienced a lovely day. High tide brought nice numbers of
waterfowl, although the diversity was low. The Gadwalls that were present in
the hundreds a mere 2 weeks ago on the Maryland side seem to have relocated.
The group enjoyed watching 2 Golden-crowned Kinglets sparring in the picnic
area at close range and were then treated to 2 Ruby-crowned Kinglets foraging
with a flock of chickadees and titmice at similar close range on Haul Road. The
highlight bird may have been the lone Rusty Blackbird that was kind enough to
stay in view for several minutes. The Dyke Marsh walk will be held ever Sunday
until 13 December when we begin the Christmas Bird Count season and will resume
10 January. Our walk is Sponsored by the Freinds of Dyke Marsh and is open to
all free of charge.

Sightings
Overcast and a NW breeze met the few who ventured out to Dyke Marsh after
the rain of the last few days. We saw a good selection of middle season
fall migrants and had no sprinkles until the end. Highlight of the day were
several Pine Warblers mixed in with Yellow-rumps in two different locations
along Haul Rd.
We started off viewing the Potomac from the picnic area and noted small
numbers of Gadwall, Am. Black Duck, Mallard, No. Shoveler, Green-winged Teal
and a single Ruddy Duck. Plus many Pied-billed Grebes. We spotted a few
Great Egrets in southern flybys - looking for protected areas to forage I
would imagine. Near the Hunting Creek mudflats area a Boneparte's Gull
moved through. An early morning Red-shouldered Hawk cruised the picnic area
and a couple of 2nd year Bald Eagles were along the river.
We made our way to Ramp Rd were Golden-crowned Kinglets quickly got our
attention plus a pair of male Pileated Woodpeckers in a snag. We spotted
our first of 3 Eastern Phoebes, noted several Fish Crow, and spotted the
largish group of American Coots in the lagoon.
Down Haul Rd we encountered Yellow-rumped Warbles in a few places with Pine
Warblers mixed in- one location produced 4 easily found Pine Warblers.
Ruby-crowned Kinglets and single calling Gray Catbird added to the ruckus.
We heard a calling Hermit Thrush, spotted a Winter Wren, and noted several
Swamp Sparrows in the marsh edge. More Eastern Phoebes were encountered on
our trek to the dogleg. At the end of the dogleg we saw more Ruddy Ducks and
one Lesser Scaup mixed in. Shorebirds populated the remnant SAV beds: a few
Greater and 30-ish Lesser Yellowlegs were noted, a 3 Forster's Terns plied
the beds.
After the Field Trip, I visited the Stone Bridge and found swallows were out
- mostly Tree but one Northern Rough-winged was mixed in. More Great Egrets
were tallied and the local Cooper's Hawk lazily flew about. The trip ended
with 58 species. The list is below.
PS: A quick visit to Riverside Park to the south of Dyke Marsh produced a
nice group of Dunlin (15) plus at least 2 Semipalmated Sandpipers on the SAV
beds. The Tree Swallow population was larger, 150, but only 2 No.
Rough-wingeds were found. Caspian Terns were about 20 and Forster's about
30. Pied-billled Grebes numbered 32

Only 2 birders joined me for the Columbus Day weekend version of
the Sunday morning Dyke Marsh bird walk. It was extremely low tide and
yellowlegs were all over the aquatic vegetation feeding. Most were Greater, but we
saw and heard a few Lesser Yellowlegs. It looked like a Great Egret convention was
underway as well. A few Cedar Waxwings were perched near the marina while
Chimney Swifts foraged overhead. Coots and White-throated Sparrows are back for
the winter. However, overall species diversity was extremely disappointing.
Only Mallards and Canada Geese were present in the river. No hawks. No
kinglets. Yet is was a pleasant and delightful day.

Before beginning today's report, I just wanted to note that the data has been
compiled for the 2009 Dyke Marsh breeding bird survey and that Least Bitterns
seem to have recovered from their 2-year population decline. Prior to 2007,
reports of 6 to 10 birds with a possible breeding pair was the norm (the two
canoe survey routes cover about 2 miles). The record was 14 birds. During 2007
and 2008, we received counts of 1 or 2 birds per survey period at best.
(Surveys are accomplished once a week between Memorial day weekend and
Independence Day). In 2009, the high count was 8 birds during a survey period
with a fledgling reported during the last week of June. It was the first
confirmation of breeding since 2006. The final report for 2009 will be on the
Dyke Marsh web site.
Back to our regularly scheduled program. Eight birders joined me for a
beautiful walk this morning. The walk takes place every Sunday morning except
during the Christmas Bird Count season and is open and free to all. Passerine
and waterfowl migrants were virtually absent, but a Bank Swallow mixed in with
some Tree Swallows was a nice sighting for Dyke Marsh. Also, Forster's Terns
were present in good numbers. Great Egrets easily outnumbered Great Blue Herons
and what I assume is the Bald Eagle breeding pair was back at the Golf Course
nest. Thanks to Rich Rieger for helping with today's walk.

From 8-10am on Sunday 2 August 2009, five birders joined the regular Sunday
morning walk at Dyke Marsh (Fairfax County), sponsored by the Friends of
Dyke Marsh and free to all visitors.
The group observed small flocks of icterids (including Red-winged Blackbirds
and Brown-headed Cowbirds) flying over the parking area and adjacent fields.
Laughing Gulls, Forster's Terns and Spotted Sandpipers were also present, as
were numerous Mallards (including one female adult with five ducklings only
a few days old) and a few Ruby-throated Hummingbirds and Great-crested
Flycatchers. Osprey adults and fledglings were present throughout the area.
We observed a few Warbling Vireos; this species was confirmed as a breeder
in the southern portion of the marsh earlier in the morning by Larry
Cartwright. Hot and humid conditions developed into strong rains by 9:45am,
curtailing the Haul Road section of the walk.

Seven birders joined me for a rather pleasant morning at Dyke Marsh (Fairfax
County), sponsored by the Friends of Dyke Marsh.
Fall migration has officially begun, with Caspian and Forster's Terns, and
Spotted Sandpipers present today. The breeding season is still underway, of
course, and the group was tickled to find a female American Goldfinch on nest
at the bend in Haul Road that we call the Dogleg. Three Mallard hens were
tending to small broods of ducklings, all less than a week old. Osprey
fleglings are everywhere. It looks like most Osprey nests were succesful in
producing fledgled young. Lots of young Barn Swallows too. Big misses were
Red-eyed and Warbling Vireos. And no Baltimore Orioles!

Seven turned out for the regular Sunday Field Trip to Dyke Marsh, sponsored
by the Friends of Dyke Marsh and open to all visitors. Today's highlight
was a repeat of last week's - a grand Least Bittern show from the boardwalk
overlook at the end of Haul Rd. Both adult and juvenile were spotted by all
today. Also a third bird whose age was not immediately clear. The two birds
that flew had long flights over the water's edge next to the island. Very
nice!
The tide was high and only a few gulls were about - the terns were absent.
The Osprey are getting quite big - it won't be long until we see a few new
flyers. And one Eastern Kingbird nest still had young in it - harried
parents were flycatching bugs in the immediate area. Orchard Orioles were
still singing and we caught looks at least one new fledgling. As we
walked Ramp Road, one participant's sharp eyes spotted a Prothonotary
Warbler working the edge near the parked boat carriers - I got a brief,
partial look and it appears to be a bird-of-the-year. As we began walking
down Haul Rd we spot a young Blue Jay still begging up in the trees. Just
past Dead Beaver Beach, on a tree snag in the lagoon, a fledgling Northern
Rough-winged Swallow waited patiently for the adult to periodically stuff
bugs into its mouth. A nice confirm for our BBS! Nearby was a male Lesser
Scaup, sitting out the summer in the lagoon. We tallied 3 different Indigo
Buntings on our trip - one in the picnic area and 2 down Haul Rd. - and
always a treat for new birders. At the dogleg, we got decent looks at a
singing adult male Northern Parula; nearby many Blue-gray Gnatcatchers were
working the edges - the latter may have come from the nest we spotted last
week, which was now empty. At the end of the trail we watched the Least
Bittern show as a Marsh Wren sang from the western portion of the island.

A few people showed up for the regular Sunday morning Field Trip to Dyke
Marsh, sponsored by the Friends of Dyke Marsh and free to all visitors.
Highlight was an outstanding Least Bittern show at the boardwalk overlook at
the end of the trail. Both adult and recently fledged juvenile were noted
with multiple flights to and from the island that lies between the overlook
and the marina. Indications were that another juvie was still in the
cattails. (Note: Larry Cartwright tells me that there are many Least
Bitterns in the marsh, so canoe/kayak trips would be timely.)
We started the morning at the picnic area which was a bit slow going, save
for a fine formation of Caspian Terns foraging over the river (and many carp
under them!). A few more were on the mudflats - about 7 in all which seems
like a good number this early into the fall migratory season. An Indigo
Bunting sang frequently from the stand of trees between the picnic area and
Ramp Rd plus 3 Great Crested Flycatchers interacting; we strongly suspect
one was a fledged bird. We viewed the easily observed Osprey nest near the
boat ramp - the 3 young birds were quite big and no longer needed ma or pa
to "cut up" the fish for them as they tore through it themselves. I would
think 1-2 more weeks before fledging will start! Nearby, an Eastern
Kingbird covered up her brood in a sycamore tree. Along Ramp Rd we spotted
a recently fledged Northern Flicker.
The walk down Haul Rd produced only heard orioles and many No. Cardinals -
clearly the latter were engaged in much feeding along the trail. Along the
dog leg we found a Blue-gray Gnatcatcher STILL on nest - 3 young poked up
for feedings. Nearby was a recently fledged Red-winged Blackbird. Before
the overlook we caught a brief glance of a Yellow Warbler. At least 5
Common Yellowthroats were singing in the area, an excellent number for Dyke!
In the sailing lagoon we caught site of the Greater Scaup reported on and
off for several weeks. And, out on the river, a Lesser Scaup was noted.
Both scaup were males.
We were entranced by the Least Bittern show. And the same cattails had at
least 2 Marsh Wren singing. Today's list of 49 species is reproduced below.

Dyke Marsh in Alexandria, which is sponsored by The Friends of Dyke Marsh
and starts at 8 each Sunday morning at the south end of the parking lot to
the Belle Haven picnic area. Highlights included seeing at least a dozen
Osprey in flight and on nests, three species of swallow, a singing
first-year male Orchard Oriole, Eastern Kingbirds chasing a crow, Yellow
Warblers and Common Yellowthroats near the bend in the boardwalk, a Red-eyed
Vireo perched just above us and a male Ruby-throated Hummingbird on a
prominent perch, as well as hearing Marsh Wrens singing on the island across
from the end of the boardwalk. One lucky participant saw a Least Bittern in
flight. Juveniles seen included a crow (sp.) sitting on grass in the picnic
area, which we never saw move, Tufted Titmouse, Carolina Wren, Canada Goose
and Mallard, and a first-year male Indigo Bunting also was seen and heard. A
single Greater Scaup continues on the south side of the boardwalk.

beautiful morning, with lower humidity, blue skies, and a cool breeze. The
picnic area was pretty quiet, with the local residents too busy feeding young
to sing, I guess. We tallied 44 species. The most interesting were a single
greater scaup, still hanging around in the waters south of the boardwalk, a
singing willow flycatcher at the start of the boardwalk, and an orange scarlet
tanager. Ospreys were everywhere, and most of the nests we could see have young
in them. Here is the list:

A rather amorphous group of 14 (or was it 16) birders joined me for
the Sunday Morning 8AM Free to everyone Bird Walk at Dyke Marsh today.
It was truly a beautiful morning that started off coolish and warmed
quickly w. few clouds and light breezes. As often happens when the
birding activity steps up, the pace of the participants differ and we
form splinter groups w. runners going between groups to report good
sightings. Ed Eder joined us for a while and Peter and Molly Ross had
a following as well.
We managed to tally 51 (or was it 52) species with some nice
highlights - all three of the Mergansers, a pair of Buffleheads, a few
pair of Wood Ducks including two perched up in a tree along Haul Road,
(my FOS) Brown Thrasher and BG Gnats, a very cooperative imm Sharpie
perched up for all to see, one Horned Grebe and at least 15 PB GRebes
(overnight push?). Two, maybe three Phoebes singing close to the start
of Haul Road - Ospreys are close to saturation point-- Also had a nice
close up of a large Black Snake sunning on a low branch near the trail
to the Little Gut, joined by a second one that we saw on our way back
in. - No Va Rails or Sora at Dyke that we could see - list

The regular Sunday morning Field Trip at Dyke Marsh, sponsored by the
Friends of Dyke Marsh and open to all comers, began with 6 participants
finding a wonderful warm weather day with mostly overcast skies. Highlights
of the day were the arrival of Osprey and Tree Swallows, anticipated by all.
We spotted a pair of Osprey on the platform in Hunting Creek Bay and another
on the nest site on the island off the marina. The Tree Swallows were
flying near the (few remaining) nest boxes in the marsh.
We started off at the picnic area noting a Red-shouldered Hawk on the ground
and then perching up nicely in a tree affording us scope views. We then
spotted Common Mergansers on the river. A first or second year Bald Eagle
perched on a snag in the bay - maybe associated with one of the adults
nesting nearby off GW Parkway? We spied about 6 eagle nest viewers on the
bicycle path as viewed from the picnic area (the nest is not visible from
the south end of the picnic area). A Ruby-crowned Kinglet sang - sort of -
over our heads. We noted 5 of these sprites during the trip. Mallards and
American Black Ducks flew past. Song and Field Sparrows were obviously
migrating as representatives of both foraged in the grass in the picnic
area. DC Cormorants were off the marina on a floating platform and 2
American Coots were nearby. Down Haul Road we got fine looks at a Winter
Wren and behind us another burst into song. Along the dogleg, we spotted a
Hairy Woodpecker pair and out on the river more ducks including 10
Red-breasted Mergansers, 3 Ruddy Duck s and a Hooded Merganser. While
watching the ducks, a Cooper's Hawk tried to sneak past us, flying low over
the water to the marsh to our south. As we walked back to our cars we noted
a Yellow-rumped Warbler near the beginning of the trail. 49 species were
tallied today, and the list is below. Join us next week and see what
migration has in store!

Six birders joined me today for a windy and chilly walk at Dyke Marsh
(George Washington Parkway- Fairfax County). The walk, sponsored by the
Friends of Dyke Marsh, begins at 8:00 AM every Sunday morning, and is open
to everyone. A big thanks to Sherm Suter, who kept the figures. Waterfowl
diversity was decent today, but numbers were low. The Bald Eagle nesting
pair at the golf course is going strong. Kinglets put on a nice show and we
had close up views of both species. Big misses were Mourning Dove and
Northern Mockingbird and Sherm and I looked all over for them!

The weekly field trip to Dyke Marsh, sponsored by the Friends of Dyke Marsh,
had 3 people today! Not bad considering it was a bit chilly (but about 20
degrees F warmer than yesterday!). The Potomac River was partically frozen
and there was a slight breeze on an overcast day. Highlight of the trip was
a calling Grey Catbird about half way down the trail. We could distantly
see the ducks near the Stone Bridge (see my note from yesterday) yet we had
a few flybys and then, at the boardwalk, we could view a nice group to our
south that included 2 male Common Goldeneyes plus Common Mergansers, RB
Merganser, Hooded Merganser, Bufflehead and Ruddies. Two adult Bald Eagles
cavorted over the forest near the main marsh (and another 2 adults and 1
2/3yrd could be seen in MD). Otherwise, a fairly typical winter field trip
with 43 species noted. The list follows.

Four birders met me at Dyke Marsh picnic area for the first Field
Trip of
the New Year, sponsored by the Friends of Dyke Marsh and all are
invited to
attend. A chill breeze and overcast skies with near freezing
temperatures.
Today we did something different, and after viewing waterfowl,
walked north
along the hike-bike trail to the Stone Bridge to search for warblers.
We were successful, first finding a western Palm Warbler, then the
Orange-crowned Warbler quickly followed by the Yellow Warbler (a
bit north
of mile marker 8). Near the Stone Bridge there were 2 Palm
Warblers - one
western and one yellow. (I am tending to think there were 3 Palm
Warblers
on the stretch.) Mixed in were Ruby-crowned Kinglets (5 or so),
Song and
White-throated Sparrows, and a Cackling Goose mixed in with the
Canada
Geese. The Bald Eagle continued working on his nest, bringing in
a few
sticks and twigs. No sign of the potential mate, although I would
be surprised if a Bald Eagle would put all this effort into a nest without
a possible mate. About 30 species for the day - not quantity but
quality.
Join us for future Field Trips to Dyke Marsh, meeting every Sunday
at 8am
near the first picnic area parking lot.

Three crazy people, I mean birders, joined me today for this very cold and
windy edition of the Sunday morning bird walk, sponsored by the friends of
Dyke Marsh. Waterfowl numbers were impressive, but we were surprised by the
lack of Bald Eagles on the mud flats. No grebes either! Passerine numbers
were low because of the windy conditions, but we did get some fine looks at
both kinglet species. This is the last walk until the Christmas Bird Count
season is over. The next scheduled walk will be Sunday, January 11. Don't
forget, the CBC opens next Sunday, December 14, with three local counts,
Manassas/Bull Run, Nokesville, and the Plains.

Today's' Friends of Dyke Marsh walk was wet. Therefore, it was not
surprising that no participants showed up. Since I was in the area anyway I
decided to get into my raingear and watch birds. Although the birds were
quiet, I was not disappointed by what I saw. Highlights were Redhead,
Canvasback, Greater Scaup, Horned Grebe (lots), Am Coot (even more),
Laughing Gull, Common Yellowthroat, Brown Creeper, Fox Sparrow, and Swamp
Sparrow. A total of 44 species were seen in the rain :-)
Below you will find the lists for the 3 locations that we generally consider
to be "Dyke Marsh". Today's walk started at the Belle Haven Picnic Area

The regular Sunday morning Field Trip to Dyke Marsh - sponsored by the
Friends of Dyke Marsh - met with many, many waterfowl and a few other
goodies. The Cackling Geese were not re-found (despite valiant efforts by
Rob Hilton and Paul Pisano) but we did snag a Redhead and later many more
plus a classic winter female Greater Scaup. Besides the good waterfowl
showing (12 species of duck with yesterday's Gadwall also missing) we
encountered Laughing Gulls, Winter Wrens, both kinglets, American Pipit,
Common Yellowthroat (HY male) and Rusty Blackbird. During a sunset visit to
get a better handle on the gulls I also noted a fine looking adult Cooper's

The weekly Sunday morning Friends of Dyke Marsh bird walk was rather hot. Eight people showed up for a muggy morning of bird watching. The birds were initially very quiet and still like the air. As the morning progressed the birds became more active. A Baltimore Oriole nest was found along the main trail and we saw the birds visiting the nest several times. A single Marsh Wren was heard singing at the end of the board walk but we did not see the bird. On our way back, Betsy True, one of the participants found a Blue-gray Gnatcatcher nest. We got some great looks of the birds visiting the nest though her scope. The Caspian Terns and Forster Terns we saw were "lifers" for two of the participants. Way cool!
In addition to the birds we also saw a common garter snake and a northern water snake swimming, and a snapper turtle along the trail.
After the trip, I visited the Marina again to check on the Northern Rough-winged Swallows that Larry Cartwright mentioned and to take a few picture from the young Ospreys.
In spite of the hot weather we did well. Gerco Hoogeweg, Vienna, VA.

Well, migration is over, and the birds are consumed by the serious business of making babies. Perhaps the birders were, too, as there was exactly 1 participant in this week?s walk. However, a good time was had by all. Best birds were a first year male blue grosbeak singing just north of the Stone Bridge, and a prothonotary warbler singing to the left of the Haul Road just 20 yards from the beginning. Otherwise, the most interesting sighting was 3 different watersnakes swimming across open water. Full list follows, with relevant notes for the breeding bird survey:

An interesting day at Dyke Marsh for the regular Sunday Field Trip sponsored by the Friends
of Dyke Marsh and free to all who attend. The first interesting item was some sort of running
or jogging event which completely consumed all parking spots by 6AM! (This did not seem
to be good planning. It also changed my plans for early morning birding along the Hike-Bike
Trail ? oh well!) The second item was the weather forecast the day before was favorable for
migrants and participants were not disappointed! Initially, I put in an effort to find migrants for
the first 2 hours before the Field Trip. I concentrated on the marina and picnic area until the
regular start time of 8AM. Fortunately, a few people showed up despite the parking lot snafu
(about 10, down by a factor of 2-3X based upon historical reports) and the field trip
commenced more or less normally from that point on. After the Field Trip, I walked the
Hike-Bike Trail (the running event was over) for the next 2 hrs and tallied those notables.
Highlight of the Field Trip was undoubtedly a pair of male Summer Tanagers which flew over
flew the trees near the beginning of Haul Rd ? a great surprise! Also, a fine selection of
migrant warblers and orioles were found that nearly all participants got on with great looks.
The Orchard and Baltimore Orioles ? of various ages ? were a delight to behold and we got
scope views of these. Ditto for the Eastern Kingbirds, many of which put on a flight show
over our heads. Hunting Creek Bay produced a pair of female Red-breasted Mergansers.
We could hear a House Wren and Prairie and Black & White Warblers near the trees
between us and the ramp road. We visited a few of the traditional spots, such as the Osprey
nest near the marina boat ramp where mama was found sitting upon eggs. Yellow Warbler
was nearby all looked upon. Cedar Waxwings were high up in the trees adjacent to ramp
road and put on a good show in the morning ? I estimated 50 all told.
Near the beginning of the Haul Rd we found cooperative Black-throated Blue and American
Redstart. Plus Red-eyed Vireo, a less than cooperative Northern Parula, a couple of Gray
Catbirds and some of the local residents. The end of dogleg produced a Swamp Sparrow,
more orioles and Yellow Warblers and Blue-gray Gnatcatchers. Glimpses of a pair of Great
Crested Flycatchers and a Warbling Vireo were all we could manage. We were unable to find
any Marsh Wrens.
Before the Field Trip, the boat ramp road area and nearby picnic grounds held a few other
birds such as Nashville, Chestnut-sided, Bay-breasted, and Canada Warblers and a
White-crowned Sparrow. My early afternoon stroll on the Hike-Bike Trail produced several
Prothonotary Warblers, more Warbling Vireos and additional Northern Parulas and Red-eyed
Vireos. Hunting Creek mudflats added Greater Yellowlegs and Spotted Sandpiper. I put the
whole list of 73 species below so others can get a feel for what was present that morning.

The regular Sunday morning (8am) Field Trip to Dyke Marsh, sponsored by the
Friends of Dyke Marsh for the last 18 yrs or so and open to all participants
met today at the picnic area to a breeze in slightly cool weather, and over
cast skies. It was a not as active today bird-wise as last Sunday, perhaps
due to the weather or the impending weather front coming upon us. Highlight
was a Common Goldeneye, spotted near the end of the trip from the boardwalk;
42 species were recorded.
We started off at the Potomac River's edge and scanned through the ca. 700
Canada Geese. We found American Black Ducks, a small group of Buffleheads,
many Mallards, 2 Pied-billed Grebes a Double-crested Cormorant and a large
group of American Coots (whose numbers today were about 400, reduced from
last week). Two adult Bald Eagles flew about and the typical 4 gull species
were easily noted. On the mudflats of Hunting Creek, 5 Great Egrets were
spotted.
The picnic area produced not one but 2 Brown Creepers giving all fine views
as they climbed tree trunks near the water's edge. In the marina area we
spotted a single Lesser Scaup - or at least it seemed like a Lesser Scaup!
This bird appeared to have faded adult male plumage of Lesser Scaup but with
a white band near the nail of the bill. Unfortunately, we did not have a
scope with us at this time, so this observation is suspect. Otherwise, the
bird had a flattish head - although not peaked over the eye - and had the
aforementioned male character. It did not hold its head up like a
Ring-necked Duck, nor have any Ring-necked plumage characteristics (or
characteristics similar to hybrids, see Mullarney et al, "Birds of Europe"
for some paintings of hybrid divers and text), and so it is thought to be a
Lesser Scaup with a slightly out of character bill coloration.
The trip down Haul Rd produced not one but 2 very shy Winter Wrens which
were quite vocal with their "telegraph-like" call notes yet maintaining
strict avoidance of visibility to the observers. Oh well!
We spotted a dozen Hooded Mergansers and then 6 Ruddy Duck in the marina
lagoon. The sparrows were thickest along the dogleg with at least 10 Swamp
Sparrows noted and even more Song and White-throated Sparrows were present.
On the boardwalk we spotted the previously mentioned Common Goldeneye,
female, off the nearby island. On our way back to the car, we got a few
drops of drizzling rain upon us, but nothing too significant.
Next week Larry Cartwright leads the last official Field Trip of the year -
Christmas Bird Counts start after that. (Of course if you visit Dyke please
send your field list to this author for addition to the FODM database.) All
are welcome to join in the upcoming CBCs - contact me if you have interest

Larry Cartwright led the regular Sunday morning Field Trip to Dyke Marsh
today, sponsored by the Friends of Dyke Marsh for about the last 18 years
and open to all comers - we meet in the picnic area by the first parking
lot. About 7 people joined today under partly sunny skies, relatively
windless conditions and jacket weather (50-60F). It was an average day for
the trip, netting about 51 species.
We started off checking the ducks in the river and noted the many Ruddy
Ducks and American Coots. Mixed in were Gadwall, Mallard, No. Shoveler, and
Bufflehead. Later on a group of Lesser Scaup few past and then a smaller
second group sat down amidst the other ducks. Whilst watching the ducks,
an Osprey hovered into view.
Haul Road produced many calling, yet hidden, White-throated Sparrows. An
adult Red-shouldered Hawk was near the marina - later we spotted a first
year Red-shouldered Hawk along the dogleg. Just before the dogleg, we heard
a Winter Wren and it was reticent to show itself (typical!). As we walked,
Northern Flickers flew past. Yellow-rumped Warblers were along the dogleg
and, near the end, many more by the boardwalk; Cedar Waxwings were also at
this location. And we actually starting seeing sparrows along the dogleg!
A White-crowned Sparrow was near the end, too. We spotted a couple of
Turkey Vultures and a Sharpie over the trees to the west. On the way back,
we heard a Rusty Blackbird near the marina. The trip list is below.

SightingsEight people joined me for this Sunday morning's edition of the Dyke
Marsh birdwalk. The participants included Erik Oberg who assured me that
he is still functioning as the biologist for the NPS. The highlights included
several warblers associated with small chickadee and titmouse flocks at
Dead Beaver Beach (the open area facing the water just north of the peninsula on
Haul Road) and the Dogleg (the base of the peninsula). Hummingbirds were in
aggressive mode today, with two teaming up to harass a Pewee at the Dogleg
and another two giving chase to each other at the boardwalk. A small fixed-species
kettle of raptors over the treeline south of Haul Road provided the onlookers a
good deal of satisfaction. Duck numbers are disappointing. A handfull of
Green-wing Teal flying over the Little Gut was the only non-Mallard ducks we could
find.

A fine turn out for Sunday's Field Trip to Dyke Marsh, sponsored by
theFriends of Dyke Marsh for the public each Sunday at 8 am. About
10 people showed up for great weather and the top highlight of the day was
likely the scope views of Trail's Flycatcher in the picnic area, near the river's
edge. Classic looks could be seen by all. Another top highlight was
Boneparte's Gull, spotted by Larry Cartwright. Over 60 species were found.
We started in the picnic area and found Pied-billed Grebe, Northern
Shoveler and Blue-winged Teal relatively close by. Two Bald Eagles (adults)
were on the mudflats and many Osprey were observed. Two Eastern
Kingbirds were nearby to the aforementioned Trail's Flycatcher. Pileated
Woodpecker was briefly seen here, too. A few Lesser Yellowlegs were on the SAV
mats.Walking down to the marina we came upon a small mixed group of
migrants with Yellow-billed Cuckoo, Ruby-throated Hummer, Great Crested
Flycatcher, Yellow Warblers, Prothonotary Warblers, Northern Waterthrush, and
Blue-gray Gnatcatchers. Caspian and Forster's Terns were flying this way and
that. Another Prothonotary was on Ramp Road which gave all fantastic
looks and a few Gray Catbirds were here, too.
At the boardwalk overlook at the end of Haul Road was a Red-shouldered Hawk,
more Blue-winged Teal, our first of season Green-winged Teal launching into
flight from a marshy island and 4 Tree Swallows.

Nine people attended the birdwalk at Dyke Marsh this morning, sponsored by the
Friends of Dyke Marsh. Migrants are definitely showing up. The waters off the
picnic area were very active. The floating maps of hydrilla held several groups
of shorebirds, including a dozen lesser yellowlegs, 6 least sandpipers, 1
semipalmated sandpiper, and 15-20 unidentified peeps (too far out). Also in the
vegetation were a pied-billed grebe, 6 blue-winged teal, 3 Forster's terns and
4 Caspian terns. Along the trail we encountered several small groups of orioles

Seven birders joined me for this Sunday's edition of the Dyke Marsh
Bird Walk.
A mild, sunny, but breezy day welcomed our group. It appears that
that some of
the passerine breeders (Yellow Warbler for example) may have
already left, but
fall migrants (Laughing Gull, Forster's Tern, Caspian Tern) are
showing up.
Ospreys put on a show, with 19 present, including 2 nests still
containing
nestlings. On a sad note, we could not find one Marsh Wren or
Least Bittern.
Marsh Wrens have been on a downward slide for 7 years and Least
Bitterns seem
to have suffered a drastic decline between 2006 and 2007.

A total of nine people turned out in typical midsummer weather for
this morning's bird walk at Dyke Marsh. No surprises, but
nonetheless a pleasant morning to be out and about before the
afternoon heat. The local Ospreys population seems to be enjoying
a successful breeding year -- the birds were flying all over the place
up and down the river. Both species of orioles had young begging to
be fed. While we only got a brief view of a Prothonotary Warbler,
another birder reported seeing three of them. The complete list

Belated report from Dyke Marsh - Alexandria - glad some folks were able to
try for the Seaside Sparrow - Kurt Gaskill tells me that they breed along the
Potomac to around the Rappahanock River, so it didn't disperse as far as I
thought it might. A great spot by Rusty at the end of the boardwalk!
Some other fine birds include the now 2 American Wigeons that were dabbling
w. the mallards at the north end of the picnic area. Peter spotted us a Black
and White Warbler as we started down Haul Rd. and it was looking somewhat the
worse for wear. We spied a fledged cowbird being fed by a Carolina Wren and
Peter and Rusty picked up a fledged Yellow Warbler being fed by an adult male.
One Least Bittern gave us nice looks in the Little Gut. At least 2 Great Egrets
were present and an early stop by the mud flats produced 2 Killdeer and 3 Wood
Ducks. Ed Eder reported a Spotted Sandpiper that eluded us and also Brown
Thrasher w. young near the wood bridge on the peninsula. We missed the young
'uns, but got to see one adult.

Sightings
Wonderful cool temperature, low humidity, mostly blue skies and slightly
breezy conditions met about 10 participants to the Friends of Dyke Marsh
Sunday morning Field Trip, free to all and we meet at 8AM in the south
picnic area. Top bird was a male American Wigeon. Certainly not unknown in
the summer, but not often seen in JULY! I suspect it's the same as the one
observed a few weeks back in the same place - Hunting Creek Bay, between the
picnic area and the Stone Bridge.
Birds were quite active and we had a grand time watching them come and go in
the picnic area. Young Orchard Orioles were clearly on the wing, following
adults back and forth. An Eastern Phoebe hunting over the water in the
picnic area; probably a dispersal bird as the species does not breed at
Dyke. But House Wrens appear to be feeding young in the nearly dead tree in
the south central picnic area - the cavity is near the top of a vertical
limb stub. Eastern Kingbirds were also quite conspicuous in many locations
from the picnic area and along Haul Rd; all were amused during one instance
where 2 kingbirds ganged up on a Fish Crow. Osprey young are getting quite
big now and parents were doing a lot of fishing to keep up with the growth.
A single Prothonotary called from the woods next to Ramp Road but it would
not pish out. And a Gray Catbird is still in this same location. Down the
trail we heard an Acadian Flycatcher in the woods and later a pair of
Red-eyed Vireos - apparently adults. Only one faint Warbling Vireo was
heard in the woods just south of Dead Beaver Beach. Viewing from said beach
we could see Tree Swallows bringing food to a nest box - on a moored
sailboat! We suspect the Common Yellowthroats are nesting near the trail by
the dogleg bend - a singer was in the woods and a calling bird in some
nearby bushes. On the way back, a single Baltimore sung once along the
trail. And near the parking lot were a mixed group of chickadees and
titmice where the titmice were mostly juvies, some still showing gape
coloration.

Another beautiful morning for the weekly Dyke Marsh walk. The
highlight was least bittern, which was unusually cooperative. From the platform at
the end of the boardwalk I found a brightly-colored one hunting on the mud
along the edge of the water (tide pretty low). I got it in the scope and we all got
great looks. It eventually flew out of view, and later we saw the same
one(?) fly over the marsh and drop into the grass. A little later we saw a rather
plain-looking least bittern flying over the grass, joined by a more
brightly colored bird. Rather than quickly dropping into the grass, they kept
flying until they disappeared behind some trees.
Other items of note were 4 each of baltimore and orchard oriole, with
one of the baltimores a young bird being fed by an adult. We saw a
goldfinch working on a complete-looking nest. Warbling vireos appeared to be absent
from the picnic area, but two males were loudly singing past the dogleg. All
the osprey nests appeared to be holding multiple large young. We heard at
least 2 marsh wrens singing from the grass, and I heard a house wren from the
picnic area. We also saw a brightly colored parrot in the marina.

A wonderful clear morning that was coolish to start but started warming up
to late June temperatures near the end. And a typical Field Trip at Dyke,
sponsored by the Friends of Dyke Marsh and free to all (meet at 8am near the
first parking lot). The theme from last week was continued as more species
were going silent early in the morning, after singing for a bit. We managed
to see 3 different Orchard Orioles but heard only one Baltimore. The
grackles, starlings and robins were out in force and juveniles were evident.
A young Northern Mockingbird was on its own in the picnic area. Eastern
Kingbirds were found in several places - one good spot was the mulberry tree
near ramp road and the bathrooms which attracted several other birds
including a pair of Gray Catbirds. The main picnic area hosted a pair of
House Wrens - unusual at Dyke as 15 years of breeding bird surveys have yet
to produce a pair until today!
Osprey young are getting bigger - the nest near the boat ramp is a
photographer's delight and the young are already bigger than any passerine.
Keep up the good work! A few Mallards and Canada Geese were seen in Hunting
Creek Bay and the passages in between the islands off the marina - one such
passage held a nearly full grown Mallard with mom. We saw many Great Blue
Herons but no sign of Least Bitterns this time. Common Yellowthroats seem
to setting up house near the dogleg in Haul Road. The House Finch in the
Sycamore near the bridge along the dogleg nest appears to be occupied. And
the end of the dogleg at the board walk produced 4 Northern Rough-winged
Swallows hanging out in the bear branches of a tree.
Earlier in the morning, point counts along the bicycle path produced
Prothonotary Warbler, more orioles of the Orchard and Baltimore persuasion,
Acadian Flycatchers, a Red-bellied Woodpecker carrying food, and a Pileated
Woodpecker.
All in all a typical summer day of breeding at Dyke! - Kurt Gaskill - June 17, 2007.
Sightings
Notwithstanding the closure of the Geo. Washington Parkway for a
race, a total of 15 people turned out on a beautiful sunny morning for the weekly
Sunday bird walk at Dyke Marsh. A total of 47 species were seen. The highlights
were a Horned Grebe which flew in and landed right in front of us as we
were beginning the walk, nice lingering flocks of Ruddy Ducks and Red-breasted
Mergansers, and a sole Yellow-throated Warbler showing off in the sunlight. A pair of
Hermit Thrush kept leapfrogging each other as we moved down the path.
Yellow-rumped Warblers and Blue-grey Gnatcatchers made themselves
conspicuous -- a pair of Gnatcatchers have a nest underway right where the path makes a
dogleg to the left. The complete list appears below.

Only two folks joined me for today's edition of the Dyke Marsh walk. Evidence
of spring was all around us despite the windy conditions. We found one Eastern
Phoebe in the parking lot and a second on Haul Road. One Dark-eyed Junco (not
normally a wintering bird at Dyke) was foraging in the picnic are. The river
hosted three Horned Grebes, Wood Ducks (3 pairs and a singleton), and small
numbers of Common and Red-breasted Mergansers, Buffleheads, Canvasbacks, and
Lesser Scaup. Song Sparrows were everywhere. We observed a Hermit Thrush and a
perched Tree Swallow and heard an Eastern Towhee just south of Dead Beaver
Beach. Bonnie Ponwith conjured up a half dozen Killdeer in the marsh.
Five Osprey nests are now occupied.
1. The nest on the platform at Port O'Vecchio contained one bird
2. The nest on the pilings in the channel contained one bird
3. The nest at the marina is under construction with one bird carrying sticks
to the nest site
4. The nest at the root site on the island adjacent to the marina is under
construction with a bird ferrying sticks to the nest site
5. A new nest is under construction on the island south of the platform at the
End of Haul Road. This replaces the nest that was lost last July when heavy
winds blew down the snag hosting the original nest.

Seasonably weather this morning at Dyke Marsh - that is, if you discount the
strong wind from the north! The wind made it chilly but the birds continue
to do their thing. An Osprey was reported carrying sticks to the Hunting
Creek Bay nest site. Three Osprey sites were occupied with an Osprey
sitting in last year's nest - the aforementioned Bay platform, the Port
O'Vecchio site, and the root site near the marina. Another Osprey was
spotted near Pipeline Bay. The cold wind did not stop the Tree Swallows as
several were spotted flying back and forth near the shoreline. A good duck
show with many divers coming close to the group for good looks (fortunately,
we had a scope for some of the other, more distant, looks!). Highlights for
this group were Gadwall (8), American Wigeon (18), Redhead (4), Bufflehead
(6) and Common and Red-breasted Mergansers. Plus 3 Horned Grebe with one
displaying obvious plumage change. As we started down Haul Road we were met
by a single Rusty Blackbird which came in pretty close - about 20 feet near
eye level. We all got fine looks at various Song Sparrow plumages as this
species was foraging along Haul Road along nearly its entire length. And as
we were scanning waterfowl from the first platform a migrating Eastern
Bluebird was heard. After the Field Trip - sponsored by the Friends of Dyke
Marsh and open to all comers every Sunday at 8AM - I went to the Hunting
Creek mudflats to check on gulls. No unusual gulls but there was one Field
Sparrow singing at the little wetlands by the apartment building. The day
ended with 50 species tallied.
By the way, since the Osprey activity signals the beginning of the breeding
season at Dyke Marsh, let me note that Friends of Dyke Marsh conduct a
breeding bird survey at Dyke. This will be the fourteenth year that the
survey using full BBS protocol employed will be done. Volunteers are always
welcome. Contact the coordinator, Larry Cartwright (prowarbler@verizon.net) for more information. By the way, this is a brilliant
opportunity to paddle a canoe into the marsh and find Marsh Wrens and Least
Bitterns! New birders are ALWAYS welcome! Kurt Gaskill - March 11, 2007.

A cold morning with little or no wind - 17 F (-8 C) and lots of ice greeted
a small turn out today (up to 5 at one point) for the regular Sunday morning
Field Trip to Dyke Marsh, sponsored by the Friends of Dyke Marsh and free to
all. The day's highlight was the obvious (and seasonal) build up of Common
Mergansers on the Potomac; we estimated about 500 birds. The Bald Eagles
were down from last time I was here, 2 adults and 3 immatures. Close in to
the picnic area was the open water channel flowing out of Hunting Creek and
this attracted many Mallards, 2 American Black Ducks and the typical 3 gull
species. More American Black Ducks were out off the mudflats. Our trip down
into the marina netted our first look at a first cycle Red-shouldered Hawk
plus Bufflehead and Red-breasted Mergansers. The walk down Haul Road was a
constant feast of close in sparrows, including the leucistic (partially
white-headed) Song Sparrow that allowed us to get as close as 12 feet. A
single Gray Catbird called along the trail, and a couple of Winter Wrens and
Ruby-crowned Kinglet were along the first half of the trail. A surprise
just north of the dogleg was a Hermit Thrush - never common at Dyke. Along
the way we were met with many Red-winged Blackbirds singing "kok-a-lee";
northbound migrants that were putting in some practice on territory songs. A
single Common Grackle - another northbound bird - was near the bike trail. The
end of the trail near the boardwalk brought us more ducks and two Red-tailed
Hawks. On the way back we spotted a Fox Sparrow by the little bridge on the
dogleg. After the trip I checked the mudflats by the Stone Bridge and added 2
Killdeer. The list of today's 47 species follows.

Winter's mild touch came upon Dyke Marsh this morning where 6 birders met
for the weekly Sunday Field Trip (starts at 8am and free to all) - a chill
wind from the north caused us to break out the gloves for the duration. We
started off in the picnic area to a grand Bald Eagle show with about 10
immatures and 8 adults noted, most over the nearly frozen river-side
mudflats - and from that point on hardly 5 minutes would go by without
spotting a representative. Very Nice! This is one of the larger counts of
Bald Eagles at Dyke and certainly the largest during the month of January.
Could the cold weather have driven them to Dyke? Or have these been held up
from their northward travels by the cold front? Or has the local population
grown so that immature birds are just more common in these times? Whatever
the case, 2 adults were seen on/near the nest near the Wilson Bridge,
Maryland side.
We walked the river's edge to the marina and found very few passerines - the
wind must have swept them into the interior of the preserve. Red-breasted
Mergansers were easily found on the Potomac. A large group of Canada Geese
could be seen far to our north against the shoreline near the Stone Bridge.
A few scattered Bufflehead were more in the middle of the river. A pair of
Pied-billed Grebes was inside the marina bay area. Here we saw our second
Belted Kingfisher; all today appeared to be males.
Our walk down Haul Road produced many sparrows - Song and Swamp Sparrows
were evident in larger than usual numbers along the trail suggesting the
recent cold had sent them - we tallied 65 Song and 14 Swamp Sparrows for the
day. Only a few Red-winged Blackbirds were noted and just a single Winter
Wren was observed. We did chance upon a perched adult Cooper's Hawk which
presented scope views. Later, when it moved, the Blue Jays put up their
alarm calls. Near the dogleg, a large group of Song Sparrows eventually
produced a fleeting glance at an American Tree Sparrow - unfortunately not
long enough for Ed Eder to unholster his camera! But the Gray Catbird came
out and stayed visible for several minutes both on our first pass and then
on our second pass as we retraced our steps to the car. And a Brown Creeper
was spotted here by the keen eyes of Sandy Farkas. The remainder of the
trail produced more sparrows, both Golden-and Ruby-crowned Kinglets and more
views of waterfowl on the river including American Black Duck (close in to
the marsh), Common Mergansers, a single Hooded Merganser and many Lesser
Scaup. We noted a half dozen Great Blue Herons huddled on the island off
the end of the boardwalk and an adult Red-shouldered Hawk flew out from the
island and over our heads at trail's end.
After the trip, Sherman Suter and I visited the Hunting Creek mudflats at
the Stone Bridge but did not turn up anything unusual, although we tallied a
new species for the day with 7 Killdeer foraging over a section of unfrozen
mud. We netted 48 species at Dyke today. Kurt Gaskill - January 21, 2007.
Sightings
Five birders joined me for today's edition of the Friends of Dyke Marsh. The
day started poorly, but got progressively better, and the sun even briefly
appeared. Highlights were 2 Singing Fox Sparrows and a Field Sparrow near the
dogleg, 2 singing Winter Wrens on the peninsula near the boardwalk, and 9 Bald
Eagles (5 immature and 4 adults). Duck numbers are still low. Perhaps the front
pushing through this Tuesday will bring more birds to our area. Nothing really
noteworthy, but it was nice to see a fine assortment of sparrows. And Downy
Woodpeckers and White-breasted Nuthatches seemed to be everywhere!

The first of the new calendar year Dyke Marsh Field Trip took place today
with nearly a dozen folks in attendance, and relatively mild January
weather. The highlight of the trip was a Peregrine Falcon perched on a low
branch stuck into the Hunting Creek mudflats (river side) first thing. We
also noted 4 Bald Eagles - all adults and two of which were perched in the
Maryland/Wilson Bridge nest. Red-breasted Mergansers put on a fine display
in Hunting Creek Bay as well as near the end of the board walk - great scope
views were had and their red eyes were easily seen! The walk down Haul Road
was mostly uneventful, both kinglets showed up and a Red-shouldered Hawk
perched on a tree on one of the islands. And over flying Gadwall was noted,
a couple of Bufflehead were in the river, a good-sized kettle of vultures
were noted over Maryland, a couple of north bound DC Cormorants were spotted
(huh?), a single Pied-billed Grebe off the boardwalk was observed and at
least 8 Winter Wrens were tallied, including 2 that actually showed
themselves for a sum total of 5 seconds and one singing. We tallied 40
species for the day.

Sightings
Seven people joined me this morning for the regular Sunday Field Trip at
Dyke Marsh. It was a gorgeous day, bright blue skies and only a little on the
cold side. But there was nothing exceptional on the birding front. No vocal or
visual signs of the ten Winter Wrens noted last week, though the habitat is
just fine for them; I am sure there must have been some still around. Ditto for
the Fox Sparrow. But we did see quite a few Swamp Sparrows, including one
that sat up brilliantly for quite a while, giving one of our number a splendid
life bird.

The immature Bald Eagle: First spotted in bare trees near the new bridge,
Virginia side, very close to an adult bird. Later they were seen from the Stone
Bridge on two small 'bushes' in the mud flats, with the adult later coming
to the same 'bush' as the immature bird. Observed eventually at 500 yards
under 45 power telescope.
Size of the immature bird was equal to the adult, and they were clearly
"together".
The head of the immature bird was patterned like an Osprey, except that the
'white' bits were medium gray. The back was fairly typical: brown with many
flecks of white. The throat and upper breast appeared to be solidly dark
brown, with only a few small flecks of white; the lower border of this area was
a deep zig-zag. The strangest part was the lower breast and belly: clear white,
but dotted all over with black, which reminded me of a Martial Eagle. No
details of the tail could be seen. Stephen Eccles, December 3, 2006.
Sightings
Eight people joined me for the regular Sunday morning Field Trip at Dyke
Marsh, sponsored by the Friends of Dyke Marsh and free to all. We started
in some medium morning fog which burned off into a beautiful day with light
breezes from the south. Top bird was Fox Sparrows: two of which perched up
nicely for all to see at close range - the first along Ramp Rd and the
second along the beginning of the dogleg. There was a third Fox Sparrow
singing brief stanzas of its song near Dead Beaver Beach.
We started out in the picnic area - now mostly bereft of leaves except for a
few bushes. Birding began with kinglets plus a couple of juncos -
curiously, juncos are never common at Dyke; the relative lack of conifers
for roosting may be the reason? Our scan of the Potomac produced only
Mallards plus the 4 typical gulls and a few DC Cormorants. Fortunately, Ray
Smith snatched a male Lesser Scaup out of Maryland waters to improve our
waterfowl list (good hands Ray!). Two adult Bald Eagles on the mudflats and
2 more found as the day wore on. Brown Creepers were also present in the
picnic area and all got fine looks of at least one. Belted Kingfishers put
on a good show starting from the picnic area and continuing through the
marina and then at the end of the trail on the boardwalk deck - including a
pair dueling over winter fishing rights. An immature Red-shouldered Hawk
near the marina got scope looks by all. More kinglets were observed along
Haul Road plus a single Yellow-bellied Sapsucker that was seen by a few.
Haul Road produced a good number of Winter Wrens - 10 in all - including 2
that broke out into song and a couple that actually SHOWED themselves!
Excellent numbers of White-throated Sparrows along the trail, too. As we
got to the marsh edge, we encountered many Swamp Sparrows. The trees held
finches -red and gold were the colors, plus Red-winged Blackbirds. At
trails end we added 2 Pied-billed Grebes near the island, had a flyby and
southbound Forster's Tern go past at arm's length, and, as we retraced our
steps to our cars, a Turkey Vulture popped up overhead.
I finished my day at Dyke counting gulls at the Stone Bridge near sunset -
the tide was lowish. Laughing Gull numbers were about the same at
Ring-billed Gulls - I tallied ca. 1350 each. Also there were 3 surprises -
a fourth year Lesser Black-backed Gull, 2 male Bufflehead and a Red-throated
Loon. I tried to convert the loon into something more conventional or even
unconventional, but the dainty upturned bill and lack of chin strap stopped
me. The latter is a fine and unusual bird in our Northern Virginia area.
The species total was one shy of fifty. Kurt Gaskill November 26, 2006.
Sightings
Six birders joined me for this Sunday morning's version of the Dyke Marsh walk
(southern Fairfax County). We had great views of Bald Eagles, hunting
accipiters, and a Red-tailed Hawk. Cedar Waxwings and American Robins feasted
on poison ivy berries. Flyover Tundra Swans delighted the group. The big
disappointment is that there are still virtually no ducks present.

A fine day at Dyke Marsh for 6 visitors during the regular Sunday Field Trip
at Dyke Marsh, sponsored by the Friends of Dyke Marsh and free to all.
Having great looks at a migrant flock in the picnic area was everyone's wish
and it was granted with a group near the boat ramp mostly coming down to the
20 foot level that left everyone pleased. We sat on a picnic table and
watched the them - first the Black-throated Greens. Then this Blackburnian.
The Black & White and Magnolia's stayed in the back ground. But the
Blackpolls came right down showing faint, blurry streaks on off-white
breasts. Then a Yellow Warbler came by - muted almost to a yellow-green all
over which Dunn indicates is the subspecies "amnicola". A Chestnut-sided
soon came down and showed all its lime-green back. A couple of
Yellow-rumped Warblers were present. And here and there were a few Northern
Parulas. All of this with a background of Forster's Terns diving nearby,
Bald Eagles flying about, huge groups of Laughing Gulls flying overhead, and
the usual Dyke Marsh woodpeckers (all the typical year-round ones were
seen), American Robins, etc.
Down the trail a few more warblers showed themselves, we spotted a calling
Swamp Sparrow, noted Coopers, Red-shouldered and Red-tailed Hawks. We also
spotted Red-eyed Vireo and Eastern Wood Pewee (and one of the latter was
singing). A Virginia Creeper high up in a tulip poplar attracted many
American Robins to its berries and to the delight of all one Gray-cheeked
Thrush! House Wren and Common Yellowthroats along the dogleg plus
Pied-billed Grebes and Green-winged Teal added to the day's lists. We noted
a few Turkey Vultures which obligingly flew across to Virginia and kettled
up over the picnic area. And Ed Eder told of us of a few Ruddy Duck at dawn
near the boar ramp. All told, the Field Trip netted 63 species.
Afterwards, I visited the Stone Bridge to add in a few species and check out
the shorebirds. The payoffs here were many Killdeer, Greater Yellowlegs, a
Pectoral Sandpiper with a bum leg, and 3 White-rumped Sandpipers.
What will next week bring?

Several participants showed this morning for the weekly Dyke Marsh bird walk,
and things were pleasant until we hit Haul Road. If you go to Dyke Marsh,
please prepare yourself with lots of insect repellant. Those that had it were
fine, while those of us that did not had a difficult time.
Few species of migrants were about, but there were several good birds to keep
it interesting. There were two PIED-BILLED GREBES - one off the picnic area,
the other off the end of the boardwalk, a continuing MARSH WREN chattering, a
returning SWAMP SPARROW, and five BALD EAGLES of varying ages perched on the
mudflats at low tide.

Five of us enjoyed the weekly Dyke Marsh bird
walk, and were pleased to get a
respite from the recent hot weather with today's
temps not exceeding the
mid-seventies. Top birds were a LEAST TERN observed flying
south off the boardwalk area, and
two LEAST BITTERNS (one heard, one seen flying
across the open water), a couple
of FORSTER'S TERNS in the same area, and a
displaying MARSH WREN at the nest
near the footbridge on Haul Road.
I was not able to scan the mudflats after the walk
(high tide was before the
walk), so there were likely more Larids and possibly
some shorebirds in
addition to the SPOTTED SANDPIPERS and
KILLDEER seen off the boardwalk.
Several juvenile birds were observed today,
including BROWN THRASHER, GRAY
CATBIRD, and YELLOW WARBLERS among others.

Five birders braved a hot and humid day to join me
for today's edition of the
Dyke Marsh Sunday morning walk. It was rather
slow with disappointing misses,
such as Baltimore Oriole. However, it wasn't a total
wash. Highlights consisted
of a fledged Great Crested Flycatcher fledgling
being fed a preying mantis by
an adult in an area Jay Keller and I felt a nest might
be located during the
breeding bird survey, and 4 active Osprey nests
with an accumulated total of 8
nestlings. Kurt Gaskill reported Forster's Terns
yesterday, but we only came up
with a solitary Caspian Tern. Although most
songbirds were silent, 3 Warbling
Vireos persisted in song, 1 in the picnic area and 2
on the Haul Road peninsula.

Sightings
The regular Sunday morning Field Trip to Dyke
Marsh, sponsored by the
Friends of Dyke Marsh, was met by sunny skies
and moderate morning
temperatures with little or no wind. The highlight of
today’s Discovery
were at least 2 Gray-cheeked Thrush singing near
the Haul Rd trailhead, and
2 Swainson’s Thrush nearby. Many got good, but
fleeting looks at these
birds (will they stay for the morrow?). Earlier,
Sandy Farkas and I had
visited this same spot and, after much studying of
bird song CDs, I conclude
there was also a Bicknell’s Thrush in this same
location earlier (about
0645) – the clincher being the low chuck notes
before every other phrase of
the Bicknell’s song which ends on flat or upward
notes (listen to your tapes
and you will hear them, also see the brief note in
Jonathan Alderfer’s new
book, “Complete Birds of North America”; there was
also an upslurred call
note from another location later)
Other highlights were 2 Yellow-billed Cuckoos one
near the dogleg bend and
the other just 200 yards down from the Haul Rd
trailhead. We got fine, but
distant looks at a pair of Great Crested Flycatchers
near Ramp Rd, and we
counted 5 Warbling Vireos and saw 2 of them (4
locations, the boat ramp,
half way down Haul Rd, and two on the dogleg).
We noted at least 8 Red-eyed
Vireos along Haul Rd (still migrating), 2 Marsh
Wren, an empty Blue-gray
Gnatcatcher nest on the dogleg (fledged I would
think), 2 pairs of Yellow
Warblers on the dogleg and a single on the island
near the marina, a calling
Prothonotary Warbler on the Haul Rd about 250 yds
south of the trailhead
(this one was a surprise, not a good habitat), a
Black & White Warbler
spotted by visitors from Louisiana, and 3 singing
Song Sparrows (marina,
dogleg bend, and half way down Haul Rd).
Everyone got fine looks at various
Orchard and Baltimore Orioles and we saw two
nests that were apparently
abandoned (?).
Before the Field Trip and near the end of the day I
checked a few spots and
found a dozen Wood Ducks near the Stone Bridge
and a Peregrine Falcon
strafing gulls on the river side mudflats, 27
Semipalmated Sandpipers (no
sign of yesterdays Dunlin), a couple of Laughing
Gulls, 4 Caspian Terns, and
Prothonotary Warbler where the bicycle trail
crosses the gut.
The combined totals are listed below to give you an
impression of the birds
at Dyke this last Sunday of May.

At least 45 people joined me for this Sunday
morning's edition of the Dyke
Marsh walk. Today's highlights were a vocalizing
Black-billed Cuckoo (a good
migrant at any location), a singing Yellow-throated
Warbler (a bird that
already should be breeding at Leesylvania, Mason
Neck, or Riverbend- they are
not recorded as breeders at Dyke), a well-observed
American Bittern, and an
even better-viewed Least Bittern, both seen on the
mud flats across from the
end of the boardwalk. We heard a lone Marsh Wren
at the same location. There
are 6 active Osprey nests, a pair of Barn Swallows
nesting on a boat at the
marina, a pair of Tree Swallows in a nestbox
erected by Chip Johnston and Kurt
Gaskill off of Haul Road, an Eastern Kingbird nest
in a Sycamore south of Dead
Beaver Beach, and Blue-gray Gnatcatcher and
Baltimore Oriole nests on the Haul
Road peninsula (the former providing great views of
an incubating female). We
also witnessed the harshness of nature- a Black
Rat Snake depredating a nest
cavity full of Red-bellied Woodpecker nestlings.
Warbling Vireos were found in
the picnic area and the Haul Road. Last year's
breeding bird survey data
indicates the number of breeding pairs may be
increasing, although we do not
reach the safe date for this species until June 10.
The walk was a great time,
but the large crowd did make for some confusion. I
want to personally thank
Sandy Farkas and Henry Brooks for providing
services as co-leaders. It made my
job much easier. Now the complete list provided

This morning several birders spent a delightful morning beating the bushes for
all Dyke Marsh (Fairfax County) had to offer. Top birds included: a very close
fly-by of an AMERICAN BITTERN at the end of the boardwalk as it flew into the
nearby marsh, a vocal and bright male WILSON'S WARBLER of which everyone got
great close-in views, MAGNOLIA WARBLER at the beginning of Haul Rd, WARBLING
VIREOS, and two NORTHERN WATERTHRUSHES. A small mouselike tan-colored bird that
flew into some marsh grass just off the boardwalk may have been the
previously-reported Sedge Wren, but the look was not sufficient and it was not
calling. The morning's list follows - 70 species.

Sightings
We led the Dyke Marsh field trip this morning. Five other birders joined us
for a good day out. Highlights were 1 Common Loon, 1 House Wren, 1 Gray
Catbird, 1 Rusty Blackbird and 1 immature White crowned Sparrow. We also
had 1 small Canada Goose that may have been a Cackling. The bird was about
1/3 smaller than the Canadas around it, Mary Alice was able to get a look at
the bill and thought it short and stubby. We are leaving it as
un-identified though as it could also be just a small Canada.
An obliging Red shouldered Hawk and Bald Eagle posed well for the
photographers in the group.
The list follows, the first number is for the picnic area including Hunting
Creek and the second is for Dyke Marsh itself.

A beautiful clear day made for many nice bird sightings. At the head of the trail, an American redstart was singing and displaying among the tangle of vines and bushes. An orchard oriole was singing high in the top of a locust tree. Blue-gray gnatcatchers were abundant. Yellow warblers were seen near the end of the trail after the bridge crossing as well as a male Baltimore oriole and a yellow-billed cuckoo. Caspian terns were feeding in the water and two loons were floating several hundred yards offshore. Although never spotted, an Acadian flycatcher was singing in the woods and several fluttery blurts of a great crested flycatcher were heard high above. Back in the parking area, in an isolated shade tree, we spotted what appeared to be a warbling vireo, suspected to be such by its song which sounded similar to a house finch. May 1, 2005 - Joe

As it was a gray, somewhat drizzly afternoon, there was almost no human activity on the bike/hike trail as I walked through Dyke Marsh. At the southern end of the Preserve, just north of Wellington, I came around a curve to find two red foxes standing in the trail. It appeared to be an adult and its offspring. The youngster went immediately into the dense undergrowth while the adult and I stared at each other for about twenty seconds. I did my staring from about 100 feet away with my binoculars. The fox then slipped away into the brush and left the trail for me to pass by. Sunday, April 24, 2005. 4:00 p.m. Tom.

While sitting in bumper to bumper traffic on the Parkway this morning (4/21/05) I saw a Bald Eagle flying west out of the Dyke Marsh area carrying some type of prey in its talons. First time I've ever seen a Bald Eagle in the wild. Very exciting.

SightingsLocated a yellow warbler nest along the trail. It's about 40-45 feet before the first bridge. If you are facing the bridge, it's on your right-hand side and about 6-7 feet high on a smaller branch above the shrubbery. The female had not yet laid her eggs (although we haven't been back since) but the pair was quite busy preparing.
