I visited the National Arboretum again this morning in the hopes of finding more birds than I did yesterday. Well, I saw some different ones, but overall I saw even fewer than yesterday. The only warbler I spotted was a chestnut-sided warbler, apparently my first at the Arboretum this year. Some other patches of activity turned out to be all common species - Carolina wrens, chickadees, titmice, and the like. Before I left I saw an immature Cooper's Hawk soaring high above the tree line. The full species list follows.
