     "Our" osprey pair at the Belle Haven marina boat ramp is featured in a 13-minute video titled "Osprey Love Nest." William Young, an Arlington writer, shot the footage and wrote the script. Ashley Bradford, an artist who lives near Dyke Marsh, does the narration. The video provides information about the behavior, anatomy and field marks of the nesting pair, as well as their interactions with other birds in the marina.
     He has shot other videos featuring egrets, coots and earned and horned grebes in the area which are on his page.

Beaver Activity in Western Dyke Marsh

   Beaver lodge
     FODMer Laura Sebastianelli is monitoring beavers in the western part of Dyke Marsh, behind River Towers. On May 1, she spotted two families, two adults and a kit and two adults and two kits nursing. At one point, she saw five adults and three kits on top of the lodge and at least one beaver swimming around. Thank you, Laura. This is a very special, little-visited part of Dyke Marsh.
