The rufous-tailed antthrush or Brazilian antthrush is a species of bird in the family Formicariidae. It is found in Argentina and Brazil.
Region
Atlantic Forest of eastern South America
Typical Environment
Occurs in humid evergreen and semi-deciduous forests of southeastern Brazil and extends into northeastern Argentina (Misiones). It prefers mature forest with dense leaf litter and shaded understory, often along ravines and near streams. The species is mainly tied to intact or lightly disturbed forest but may persist in larger forest fragments. It is a terrestrial specialist that keeps close to cover and rarely ventures into open areas.

A shy, ground-dwelling antthrush of the Atlantic Forest, the rufous-tailed antthrush is most often detected by its rich, whistled song rather than seen. Its warm rufous tail is a key field mark as it slips through dim undergrowth. It forages by flipping leaf litter for arthropods and occasionally follows army-ant swarms. Although currently not at risk, it is sensitive to forest fragmentation and benefits from protected, continuous forest.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats, low to the ground
Social Behavior
Typically encountered alone or in pairs, defending territories within dense understory. It nests low or on the ground in well-concealed sites, using leaves and other plant material. Courtship and pair bonding are discreet, with partners remaining close in dense cover.
Migratory Pattern
Resident
Song Description
A series of clear, resonant whistles, often descending or delivered in deliberate phrases that carry far in the forest. Calls include sharp notes used for contact and alarm, but the song is the best clue to its presence.
