Black-and-white Becard

The black-and-white becard is 13.2 to 15.0 cm (5.2 to 5.9 in) long and weighs about 16 to 26 g (0.56 to 0.92 oz). Adult males of the nominate subspecies have a glossy bluish black crown. They have blackish lores, a wide white stripe from above the lores to above the eye, and a thin partial white eye-ring on an otherwise grayish face. Their nape and upperparts through their uppertail coverts are gray. Their wings are mostly black with wide white edges on the secondaries, tertials, and median and greater coverts; the last two show as wing bars. Voice: The male black-and-white becard's song is a "short soft phrase of typically three mellow notes w-tuw-tuweet?" and the species' call a "short rapid trill consisting of a few downslurred notes". Males sing mostly at dawn and in the early morning.
