Dark-eyed junco (Junco hyemalis)—Steve and Dave Maslowski
Any of several species of finchlike birds (genus Junco, family Emberizidae), about 6 in. (15 cm) long, of Canada and the U.S. Juncos are usually a shade of gray; they have white outer tail feathers that are flashed in flight to the accompaniment of snapping or twittering calls. They are common winter birds. Their favoured habitat is mixed or coniferous forest, though they are often found in fields, thickets, and city parks.
