Princeton, May 1st

Despite heavy overcast and some drizzle, I stopped off at Rogers Refuge/Institute Woods before work. There was certainly some migration, although not starting numbers. The best birds were a male Blackburnian Warbler and several Rose-breasted Grosbeaks (one male was singing), and Warbling Vireo was new for the year although a predictable find.
