While at work today in White Marsh (on private property), I spied the 
following notable species:

Great Egret - 2
Wood Duck - 2
Blue-winged Teal - 1
Green-winged Teal - 15
Bald Eagle - 2
Killdeer - many
Greater Yellowlegs - 8
Lesser Yellowlegs - 15
Solitary Sandpiper - 6
Spotted Sandpiper - 3
Least Sandpiper - 2
Herring Gull - 4
Purple Martin - 4
Northern Rough-winged Swallow - 10
Barn Swallow - ~5
Rusty Blackbird - 58 (!!) I think this is the largest flock I've seen

This wetland is privately owned but not residential.  If you would like 
more info, email me privately and I'll see what I can do.
