Ground-antbirds (Formicariidae)

Black-faced Antthrush (Formicarius analis) - HBW 8, p. 703

French: Tétéma coq-de-bois German: Graubrust-Ameisendrossel Spanish: Formicario Enmascarado
Other common names: Rufous-necked Antthrush; Hoffmann’s Antthrush (hoffmanni)

Taxonomy: Myothera analis d’Orbigny and Lafresnaye, 1837, Yuracares and Chiquitos, Bolivia.
Should probably be split into two or more species, as birds in Amazonian region have different song from those in C America; geographical variation (in voice and plumage) across entire range, however, not well documented. In addition, race saturatus may contain more than one taxon, as birds from Magdalena Valley (Colombia) give same song as those in C America, whereas birds from Lara (NW Venezuela) give the Amazonian song; situation difficult to assess, as songs of virescens and griseoventris undescribed; further study needed. Form olivaceus, described from N Peru,.. View all taxonomy...
