White-winged Becard

The white-winged becard is 14 to 15.5 cm (5.5 to 6.1 in) long and weighs 19.5 to 21 g (0.69 to 0.74 oz). Adult males of the nominate subspecies P. p. polychopterus have a glossy black to almost bluish crown and nape. Their face is slate-gray below the crown and the color wraps around the back of their neck. Their back is mostly glossy black to almost bluish with slate-gray uppertail coverts. Their wings are mostly black with wide white edges on the coverts that show as two wing bars. The wing's secondaries and tertials also have wide white edges. Voice: The white-winged becard's song in Costa Rica is described as "a fast series of sweet chew notes, the first followed by a slight pause". In eastern Ecuador it sings "a pretty and melodic series of mellow notes, e.g. teu, teu, tu-tu-tu-tu-tu-tu" and in the west a slower "teu, teu, teu, teu, ti-teu, teu". In Venezuela it sings "a soft, warbled teeur, tur-tur-tur-turtur? a weak tew te tu tu tu".
