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.

[2] 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.

[3] The specific epithet is from the Modern Latin analis meaning "relating to the undertail-coverts of the vent".

[9] The black-faced antthrush feeds primarily on a variety of arthropods and also includes small vertebrates such as frogs and lizards in its diet.

It walks slowly and deliberately with its tail cocked like a little rail, sweeping or flicking aside leaf litter with its bill, and often moves in circles.

[9][15][17][18][19][20][21][excessive citations] The black-faced antthrush's breeding season has not been fully defined, but is known to span March to October in Costa Rica and to include November in Amazonian Brazil.

It does not build a conventional nest but makes a platform of dead leaves and flowers at the bottom of a tree or stump cavity.

The three subspecies of the black-faced antthrush's hoffmanni group sing "an emphatic flat-pitched introductory whistle at ca.
