A terrific flight today at Rock Creek Park, DC -- attended by a good turnout of birders as well. It started very slowly -- for a while there were more birds than birders -- but suddenly the air was filled with chips and sips and the warblers poured in! Barry and I didn't get back home until 11:30 am, as there were still birds around. Warblers: Black-throated Blue (9), Black-throated Green (30+), Black-and- White (8), Blackburnian (8-9), Bay-breasted (10), Blue-winged (3), Blackpoll (4), Chestnut-sided (40+, many adults), Canada (2), Magnolia (25), Nashville (2), Ovenbird (2), Golden-winged (1, F), Parula (1), Pine (1), Redstart (8), Tennessee (3), Wilsons (1, M), Common Yellowthroat (8). (19 spp.toto) Flycatchers: Empidonax are coming through, while Pewee numbers are way down: Least (2), "Traill's" (1), Acadian (2), Yellow-bellied (1), Empid sp. (2), Pewee (2). Vireo: Red-eyed (30+), Warbling (1) Others: Rose-breasted Grosbeak (2), Swainson's Thrush (3), Scarlet Tanager (1), House Wren (6), R-T Hummingbird (2). Still lots of Robins, Catbirds, and Cedar Waxwings around. Gail Mackiernan Barry Cooper gail@umdd.umd.edu
