The black-capped becard (Pachyramphus marginatus) is a species of bird in the family Tityridae, the tityras, becards, and allies. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. 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. Their tail is black with white tips on the feathers. Their throat is pale gray or pale whitish gray and their underparts are a uniform light gray that sometimes becomes whitish gray on the lower belly and vent. Adult females have a rufous-chestnut crown. They have a grayish spot above the lores and a broken white eye-ring on an otherwise dusky olive face. The color of their face wraps around their nape. Their upperparts are olive. Their wings are mostly dusky with rufescent or cinnamon-olive scapulars and wide rufous edges on the coverts and inner flight feathers. Their tail is dusky with buff-cinnamon tips on the feathers. Their throat and underparts are pale yellow with a dusky tinge on the breast. Subspecies P. m. nanus is smaller than the nominate but otherwise the same. Both subspecies have a dark iris, a dusky or blackish bill, and dusky grayish legs and feet.
