I made two stops in Prince George's County today, going to both Schoolhouse 
Pond and Wharf Road on Piscataway Creek.  I was at Schoolhouse Pond from 
approximately 12:45 until a little after two, and there was a small group 
of gulls on the small remaining patch of ice pushed to one edge of the 
pond.  There were approximately 120 Ring-billed Gulls, and about 35 or 40 
Herring Gulls, although gulls kept flying in and leaving.  For about 15 
minutes, an adult Lesser Black-backed Gull flew in and stood on the ice.  
It was close enough to the boardwalk that I may have gotten some fairly 
good photos of it.  Also of interest was a late adult Laughing Gull.  Non 
gulls included 15 Shovelers and 1 Pied-billed Grebe.

At Wharf Road, there were six Bonaparte's Gulls and one adult Great Black-
backed Gull mixed in among the many Herring and Ring-billed Gulls.  
Waterfowl present included large numbers of Ruddy Ducks, Ring-necked Ducks, 
and Canvasback, with smaller numbers of Scaup (mostly Lesser) and a few 
Common Mergansers and Bufflehead.
