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.

Possible
About 30% of wildlife watchers report a Black-faced Antthrush sighting in Corcovado National Park on a given day, based on 985 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 332 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February–April and June–July
In those months about 40% of wildlife watchers report a Black-faced Antthrush in Corcovado National Park on a given day, against about 10% in October, the lowest month.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-faced Antthrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 26 parks where we can rate Black-faced Antthrush sightings, Corcovado National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Tambopata National Reserve (Peru, about 30%).

GBIF citizen-science records
It is estimated from how often the Black-faced Antthrush is recorded against all the birds logged in Corcovado National Park (985 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.
