Family Ground-antbirds (Formicariidae)

Least Concern

Black-faced Antthrush (Formicarius analis)


French: Tétéma coq-de-bois German: Graubrust-Ameisendrossel Spanish: Formicario enmascarado
Other common names: Central American Antthrush (hoffmanni group)

Myothera analis

d’Orbigny and Lafresnaye

, 1837,

Yuracares and Chiquitos, Bolivia


Formerly treated as conspecific with F. moniliger, but the two differ in both plumage and song (e.g. song of present species dropping in pitch, that of F. moniliger rising). Races of present species may constitute two separate species, as Amazonian birds and those of Central America have different songs (Amazonian birds sounding closer to F. moniliger); but geographical variation (in voice and plumage) across entire range poorly documented and, in race saturatus, birds from Magdalena Valley (Colombia) give same song as those of Central America, whereas birds from Lara (NW Venezuela) give the Amazonian song; further study needed. Form olivaceus, described from N Peru, synonymized with zamorae. Eleven subspecies recognized.
