| Birds are by far the most numerous and easily observed marsh dwellers. Their variety and numbers are astounding, especially since the return of sub-aquatic vegetation that has paralleled recent improvements in Potomac River quality. One expert, Lt. Col. Jackson M. Abbott, compiled a list from over 40 years of recorded observations of 296 species seen in Dyke Marsh. Presented here are 225 of the more common ones with their seasonal abundance and breeding
data. Please report your sightings on our Bird
Sightings page, especially sightings of any
unlisted species; they will be forwarded to our Records Committee. |
