I birded the OC area on Tuesday and Wednesday with Aimee Haskew. We didn't see any King Eider or Great Cormorant, and generally speaking our observations were quite similar to what other have reported. 

Nearby highlights in MD:
Assateague Island - hordes of Yellow-rumped Warblers, a flyover Peregrine Falcon, >50 Brant, and a Wilson's Snipe (feeding next to the road).

Snow Hill - >1000 snow geese

Blackwater NWR - Hordes of geese (snows and Canadas), relatively few ducks (most impoundments were frozen), and several Fox Sparrows. A female Northern Harrier was perched atop a dead rabbit on the auto road and provided excellent views. ~10 Northern Bobwhite flushed from a bush near the visitor's center.

Nearby out-of-state highlights:
We located a red-necked grebe just north of the MD border in a private development on the sound side.

Chincoteague NWR was loaded with waterbirds, including Great Egret, Wilson's Snipe, Ipswich Sparrow, Tundra Swan, and many ducks/geese. We located a very strange looking pintail hybrid. A single adult Black-bellied Plover in non-breeding plumage was also observed.



Good luck!
