As might have been expected, there was an excellent movement of migrants last night and when we got to the ridge (picnic areas 17/18) at Rock Creek at 6:15 am, the woods were ringing with song. Bird activity continued until noon, we left at about 12:30, having tallied 17 species of warbler and other migrants. Here's hoping tomorrow is as exciting! Partial list: 1 Golden-winged, 3-4 Blue-winged, 1 Cerulean, 3 Chestnut-sided, 20+ Black-throated Green, 1 Black-throated Blue, 8-10 Ovenbirds, 1 Hooded, 1 Redstart, 2 Yellowthroats, 1 Yellow, 6 Palm (all yellow race), 250+ Myrtle (Yellow-rumps), 2 Wormeating, 25+ Black-and-White, 3 Nashville, 1 Louisiana Waterthrush, 4 Red-eyed Vireos, 20+ Blue-headed Vireos (all-time high here for us), 1 Yellow-throated Vireo, 3 Scarlet Tanagers, 3 Veerys, 5 Hermit Thrush, 1 Swainson's Thrush, 4 Wood Thrush, 3 Catbirds, 6 House Wrens, 30+ Blue-gray Gnatcatchers, 10 Ruby-crowned Kinglets, 1 Great Crested Flycatcher, 35 White- throated Sparrows, 4 Field Sparrows, 20 Towhees, 1 Broadwing, 1 Cooper's Hawk, and 2 Barred Owls. Lots of Flickers (not counted) were also about, but a definite decrease in Goldfinches from yesterday. Gail Mackiernan and Barry Cooper Silver Spring, MD
