Formicarius analis
The Black-faced Antthrush, Formicarius analis, is a charismatic Neotropical passerine, distinguished by its dark plumage and a striking black face and throat that contrasts with its rufous-brown crown, nape, and back. Measuring around 18-19 cm (7-7.5 in) in length and weighing 40-50 grams (1.4-1.8 oz), it possesses a compact body, long, sturdy legs adapted for ground movement, and a conspicuously short tail. A prominent pale or white eye-ring often provides a key field mark, breaking up its o...
This species primarily inhabits the understory of humid tropical and subtropical evergreen forests, often favoring areas with dense vegetation, ravines, or near water sources, typically at elevations from sea level up to 1000-1200 meters.
Its diet consists almost entirely of insects, particularly arthropods flushed by army ant swarms, along with other small invertebrates found in the leaf litter.
Black-faced Antthrushes are highly terrestrial and diurnal, spending almost all their time on the forest floor, often detected by sound rather than sight. Their primary foraging strategy involves following army ant swarms (Eciton burchellii being a key species), capturing insects and other invert...
The Black-faced Antthrush has an extensive Neotropical distribution, ranging from southeastern Mexico (including Veracruz, Oaxaca, and Chiapas) through much of Central America, continuing into northern South America. Its range encompasses Belize, Guatemala, Honduras, Nicaragua, Costa Rica, and Pa...
