Central Park May 1st and 2nd

Although April 30th was probably the most numerous day (I was at work), May 1st and 2nd in the park were good migration days and signalled a rapid switch from early to mid spring migrants. The species mix was different on the two days, with many Black-throated Greens on Sat and none on Sun. Best birds on Saturday were multiple Hooded Warblers, Worm-eating Warbler and Yellow-throated Vireo amongst a lot of new-for-year birds. On Sunday an early Bay-breasted Warbler (last year I had one on Apr 26th), Blackburnian Warbler, a few Blackpolls, and a Prairie Warbler. There were multiple termite hatch-outs at before 10am in the Ramble on Sunday under very humid conditions. 19 warbler species aggregated over two days with others (Cape May and Cerulean) at least reported.
