Black-faced Antbird
Myrmoborus myotherinus
Short-tailed antbird of forest understory. Both sexes have black face. Males are gray with white wingbars; females are brown above, buffy below, with cream wingbars and a white or buffy throat. Forages singly or in pairs low in the undergrowth of mature forest. Usually inhabits more mature forest than similar White-browed Antbird, but there is some overlap. Note differences in facial pattern; males lack the white eyebrow and females lack the orange eyebrow seen on White-browed Antbirds. Female Black-faced Antbirds also have browner underparts than White-browed. Listen for an even-paced series of 5–7 whistles that is slightly higher in the middle. In the southern part of its range, these whistles are pure-toned; in the north, they are harsher.
Identification
The black-faced antbird is 12–13 cm (4.7–5.1 in) in length and weighs around 16–22 g (0.56–0.78 oz). The male of the nominate race is blueish grey above, with the wings and tail slightly darker, a black face, throat and wing tips. The female is duller, mostly olive-brown with black tipped wings and light buff underparts. The different races vary in the darkness of the male and colours and pattern of the female.
Taxonomy
The black-faced antbird was described and illustrated by the German naturalist Johann Baptist von Spix in 1825 and given the binomial name Thamnophilus myotherinus. The specific epithet is from the Ancient Greek muiothēras meaning "flyhunter".<p>There are seven subspecies currently recognised, although some of these may represent separate species and others only clinal variation, and more research is needed into the species' taxonomy.
