I birded the Spit today and can't remember ever having seen such large numbers of passerines there. From the Baselands out to Peninsula D, which was as far as I got, there was flock after flock of warblers and sparrow, with dozens of birds in every flock. Most of the warblers were Yellow-rumped and Palm, but I also encountered Wilson's, Bay-breasted, Nashville, Orange-crowned, Black-throated Green, Black-throated Blue, Northern Parula, and Common Yellowthroat. The bulk of the sparrows were Song and White-throated, but there were also flocks of Swamp Sparrows, good numbers of White-crowned, and three Lincoln's. Mixed in with these flocks were Hermit Thrushes, Ruby- and Golden-crowned Kinglets, Brown Creepers, Red-eyed and Blue-headed Vireos, Yellow-bellied Sapsuckers, Flickers, Downy and Hairy Woodpeckers, Red-breasted Nuthatch, Eastern Phoebes, and Wood Peewees.
In the cattails along the shoreline of Cell 1, I found a very cooperative Marsh Wren (the first I've seen on the Spit) and flushed a Wilson's Snipe. In the pond itself were a flock of 24 Northern Shovelers, and a Great Blue Heron. Bay D had Hooded Mergansers and a single female Ring-necked Duck. The only raptor I got a good look at was an immature Bald Eagle circling overhead.
