Summary

The barred becard (Pachyramphus versicolor) is a small passerine bird
in the family Tityridae, the tityras, becards, and allies. It is found in Costa Rica, Panama, and in South America from Venezuela to Bolivia.

Taxonomy and systematics

The barred becard was originally described in 1843 as Vireo versicolor. It was later reassigned to genus Pachyramphus that George Robert Gray had erected in 1840. The genus has variously been assigned to the tyrant flycatcher family Tyrannidae and the cotinga family Cotingidae. Several early twenty-first century studies confirmed the placement of Pachyramphus in Tityridae and taxonomic systems made the reassignment. In 1998 the American Ornithological Society was unsure where to place the genus and listed its members as incertae sedis but in 2011 moved them to Tityridae.

The barred becard has three subspecies, the nominate P. v. versicolor (Hartlaub, 1843), P. v. costaricensis (Bangs, 1908), and P. v. meridionalis (Carriker, 1934).

The barred becard is 12 to 13 cm (4.7 to 5.1 in) long and weighs 14 to 17 g (0.49 to 0.60 oz). It is the smallest member of genus Pachyramphus. Adult males of the nominate subspecies have a glossy black crown and nape and greenish yellow lores and eye-ring. Their face is also greenish yellow. Their upperparts are mostly glossy black with a slate gray rump and uppertail coverts. Their wings are black with white edges on the greater coverts and remiges. Their scapulars and lesser and median coverts are white with black edges. Their tail is slate gray with white edges on the feathers. Their throat is greenish yellow that becomes white on the rest of the underparts; these colors are overlain with thin blackish bars. Adult females have a slate gray crown and nape and a yellow eye-ring; their face is a slightly more olive yellow than the male's. Their upperparts are olive green. Their wing coverts are rufous; their flight feathers are a darker rufous with buff edges on the tertials. Their tail is...
