The black-faced antthrush (Formicarius analis) is a species of passerine bird in the family Formicariidae. It is found in Central America from Honduras through Panama, on Trinidad, and in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.
The black-faced antthrush was formally described in 1837 by the French naturalists Alcide d'Orbigny and Frédéric de Lafresnaye from a specimen collected in Bolivia. They coined the binomial name Myothera analis. The specific epithet is from the Modern Latin analis meaning "relating to the undertail-coverts of the vent". In 1858 it was moved to genus Formicarius that had been introduced by the Dutch naturalist Pieter Boddaert in 1783.

GBIF citizen-science records
It is estimated from how often the Black-faced Antthrush is recorded against all the birds logged in Carara National Park (1,023 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
