Greetings,

This morning I heard then saw a Grasshopper Sparrow singing from the north 
end of the main runway at Phillip's Army Airfield at the Aberdeen Proving 
Ground in Harford County.

Other birds of not included Blackpolls EVERYWHERE, Redstart, Yellow 
Warbler, Common Yelowthroat, Parula, 10 Eastern Wood-pewee, Wood Duck, and 
3 Black Ducks.

Good Birding,
