Wing-banded antbird
The wing-banded antbird is a species of passerine bird in subfamily Myrmornithinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Nicaragua, Panama, Peru, Suriname, and Venezuela.
Taxonomy and systematics
The wing-banded antbird was described by French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 in his Histoire Naturelle des Oiseaux from a specimen collected in Cayenne, French Guiana. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Formicarius torquatus in his catalogue of the Planches Enluminées. The wing-banded antbird is now the only species placed in the genus Myrmornis that was introduced by the French naturalist Johann Hermann in 1783. The generic name combines the Ancient Greek murmēx meaning "ant" and ornis meaning "bird". The specific name torquata or torquatus is the Latin for "collared".The further taxonomy of the wing-banded antbird is unsettled. The International Ornithological Committee, the Clements taxonomy, and the South American Classification Committee of the American Ornithological Society assign it two subspecies, the nominate M. t. torquata and M. t. stictoptera. BirdLife International's Handbook of the Birds of the World treats the two taxa as separate species: the northern wing-banded antbird and the southern wing-banded antbird.
The wing-banded antbird has also been called the wing-banded antpitta and wing-banded antthrush. The "northern" wing-banded antbird has also been called the buff-banded antbird.
This article follows the single species, two subspecies model.
Description
The wing-banded antbird is long and weighs. It is distinctively plumaged, and its short tail and legs and "dumpy" body are also unusual among antbirds. The sexes have different plumage. Adult males of the nominate subspecies have a mostly black and white speckled face and the sides of the neck. Bare blue skin surrounds their eye. Their crown and nape are reddish brown. Their back feathers are grayish brown with reddish brown edges and black spots. Their rump and uppertail coverts are gray with wide rufous tips on the feathers. Their tail is rufous brown with dark brown feather tips. Their wing coverts are blackish brown with pale cinnamon buff tips and their flight feathers blackish brown with a pale cinnamon band on the edges of the primaries. Their throat and upper breast are black with a black and white speckled band below the upper breast. Their lower breast and belly are gray and their undertail coverts cinnamon rufous. Adult females have paler upperparts than males and their upper breast is cinnamon rufous. In both sexes their iris is dark brown, their bill black, and their legs and feet dark gray to fuscous. Juveniles of both sexes have a dark chocolate crown and nape; they are mostly chocolate brown otherwise with a paler grayish brown rump and uppertail coverts. Subspecies M. t. stictoptera is darker and somewhat more richly colored overall than the nominate. Black and white speckles are restricted to their face. Their breast has less black and rufous than the nominate and the bands on their wings and wing coverts are wider and darker.Distribution and habitat
The wing-banded antbird has a disjunct distribution. Subspecies M. t. stictoptera is the more northerly of the two and has a much smaller range than the nominate. It is found separately in southeastern Honduras and northeastern Nicaragua, in southeastern Nicaragua, and from the region of the Panama Canal east into northwestern Colombia. The nominate subspecies has two populations. One extends from central and southeastern Colombia, through northeastern Ecuador where it is scarce and local, and into northern Peru. The other extends from southeastern Venezuela east through the Guianas, east in Brazil to the Atlantic Ocean, and south in Amazonian Brazil to eastern Rondônia and northern Mato Grosso.The wing-banded antbird inhabits humid lowland and foothill evergreen forest, where it is found almost exclusively on and near the ground. It favors terra firme, often among hills. In elevation it occurs from sea level to about in Central America but in South America is seldom found above and typically reaches only in Colombia and Ecuador.
