I did end up with 50 species of birds (adding a Great Black-backed Gull from my window when I got home). That total included eight new species for my April/May list (in italics in the list below). I also heard a singing Baltimore Oriole from my window after getting home. My overall April/May list for the park is now 92 species with 37 from my apartment. Also seen from my window today was the first Canada Goose goslings I have seen this year.
Before getting to the bird list, a couple of non-bird photos. A very nice Tiger Swallowtail cooperatively posed in the Overlook Meadow when we were trying to track down a singing Yellow-throated Vireo.
Growing on a dead tree stump on the eastern edge of the Overlook Meadow was this very large Dryad's Saddle fungus (Cerioporus [Polyporus] squamosus). It was larger than a large dinner plate.
Today's bird list:
Great Black-backed Gull
Turkey Vulture - over the Palisades
Northern Rough-winged Swallow
Wood Thrush - singing in the Clove and on the ridge
