Plump, smooth-plumaged bird with a sleek crest and white and yellow markings on wings. Mostly clean gray with brighter rusty wash on the face. Look for rich rufous undertail. Breeds in open coniferous forests at high latitudes across the Northern Hemisphere. Winter range depends on fruit crops; sometimes descends much further south in large numbers. Often found in flocks feasting on fruiting trees like crabapple and mountain ash. Listen for their ringing trills, often given while flying overhead. Compare with Cedar Waxwing in North America; Bohemian is larger and grayer, with rufous undertail and different wing pattern.
