Black-capped Becard

The black-capped becard is 13 to 14 cm (5.1 to 5.5 in) long and weighs about 18 g (0.63 oz). Adult males of the nominate subspecies have a glossy black crown that has a blue sheen and a scaly appearance. They have a pale spot above the lores and a thin whitish eye-ring on an otherwise light gray face. The gray of their face wraps around their nape as a collar. Their back is variable from gray to black and their rump is gray. Their wings are mostly black with white scapulars and widish white edges on the coverts and flight feathers; the white shows as two wing bars. Voice: The black-capped becard's dawn song is "a soft, delicate...tew, tew’tweet that rises sharply". Its principle day song is a variable "short melancholy series of clear musical notes" written as "teeu, whee-do-weét, twee-twee-tee-eet, dear-dear or tewtewtewteé, dew-dew". It also makes "a quickly repeated fleur-de-lis phrase" and even-pitched trills "teeu, tee-tee-tee-te-ti or tre-tre’tre-e-e-e-e-it".
