At Lake Elkhorn in Columbia this afternoon I heard two WHITE-EYED 
VIREOS. (I didn't get to see them; they were hiding in some brush about 
15 feet away.) Seems a bit late.

In addition to the usual suspects, there were also

Ruddy Duck (3)
Pied-billed Grebe (6)
American Coot (1)
Ruby-crowned Kinglet (5+)
Eastern Bluebird (3)
Yellow-rumped Warbler (1)
Swamp Sparrow (2)
White-throated Sparrow (7+)
