Grey-collared Becard
Pachyramphus major
The grey-collared becard is 14 to 16.3 cm (5.5 to 6.4 in) long and weighs about 21 to 28 g (0.74 to 0.99 oz). Adult males of the nominate subspecies P. m. major have a glossy black crown. They have a pale stripe above the lores and an otherwise light gray face. The gray of their face wraps around their neck as a collar. Their back is black, sometimes with gray mottling, and their rump and uppertail coverts are gray. Their wings are mostly black with a white stripe on the scapulars and white edges on the coverts, secondaries, and tertials. Voice: The grey-collared becard's song is "a rich and constantly repeated (usually 4–6 times, and ten in c. 10 seconds) hoo wee-deet or hu whi-ditt whistle". Its call is a "begging-like eeuup-eeuup-eeuup" and it occasionally makes "squabbles and nasal agitated notes".

Pachyramphus minor
The pink-throated becard is 16.5 to 17.5 cm (6.5 to 6.9 in) long and weighs 31 to 44 g (1.1 to 1.6 oz). The species is sexually dimorphic. Adult males are mostly black to dark sooty gray. Their face and underparts are slightly paler than their back. They have the eponymous pink patch on the lower throat and upper breast, though sometimes it is indistinct. They have some white at the bend of the wing that is usually visible only in flight. Adult females have somewhat individually variable plumage. In general they have a grayish brown crown and nape. Voice: The pink-throated becard is generally quiet. Its song is described as "a clear, melodic teeuuuweeet often followed by twittering notes", "a thin, wiry, high, rising-falling, whiny tewwweeewww or a rising tueeeet?", and " a clear, rising whistle, tuuueeeE". Its calls include "a rapid chatter of squeaky whistles and whines and a sharp ik".
