As one would expect, breeding birds were very active defending territories and feeding their young. One surprise was a male Blue-winged Warbler, which was actively foraging but not singing in the first field. I had not heard about them breeding there, but the habitat seems appropriate. Other birds in the field included an Indigo Bunting, House Wrens, and a Ruby-throated Hummingbird. Oddly enough, it was my first hummingbird of the year.
Wood thrushes were singing all along the wooded trails. They were joined by a few singing Scarlet Tanagers and Ovenbirds. A few American Robins were present but unusually silent. A Veery called neared the river. While looping back to the nature center, I saw some Tufted Titmice feeding their chicks.
