There were many birds at the dairy farm near Gambrills in Anne Arundel County 
this morning, but almost all common.  The best I could come up with was an 
adult Lesser Black-backed Gull among the Laughing, Ring-billed, Herring, and 
Great Black-backed.  Many Killdeer, Canada Geese, Red-winged Blackbirds, and 
Brown-headed Cowbirds in the fields.
