The BYG was pretty quiet at first, but when I came back an hour later, there was a sudden flurry of activity. One each of white-breasted nuthatch (top L), downy woodpecker (top R), 5 or 6 chickadees (bottom L), and 5 juncos (bottom R), a mourning dove, three cardinals, and 4 common redpolls. Elsewhere, there was a flock of about 50 bohemian waxwings flying through the Arboretum, along with a flock of common redpolls (about 15), and half a dozen crows.
