Lisa went walking along the bike trail from Bethesda toward Connecticut Avenue today and saw a close Ruby-crowned Kinglet, and heard a bunch of warblers (Parula, Black-throated Green, BT Blue, Blackpoll), and Scarlet Tanager and Baltimore Oriole.
This afternoon/evening at home there have been two Swainson's Thrushes singing: one out back, the other across the street.
