The Alta Floresta antpitta is a species of bird in the family Grallariidae. It is endemic to Brazil.
Region
Southern Amazon Basin (Brazil)
Typical Environment
Occurs in lowland terra firme rainforest south of the Amazon River, especially in forests around northern Mato Grosso and adjacent southern Amazonia. Prefers dense understory with deep leaf litter, vine tangles, and fallen logs. Often near lightly undulating terrain and occasionally along stream edges but generally away from open or flooded habitats. The species is sensitive to heavy fragmentation and is less common in heavily disturbed forest.
Altitude Range
50–400 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
The Alta Floresta antpitta is a recently described species split from the Spotted Antpitta complex, distinguished chiefly by its voice and subtle plumage differences. It skulks on the forest floor of the southern Brazilian Amazon and is more often heard than seen. Its range lies within Brazil’s ‘arc of deforestation,’ so habitat loss is a concern despite its current broad local distribution.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats; mostly hops on the forest floor
Social Behavior
Typically solitary or in pairs, maintaining small territories within dense understory. Nests are placed low, often a cup or platform near the ground, with both sexes likely sharing incubation and chick care. Breeding details remain poorly documented but are thought to resemble close congeners.
Migratory Pattern
Resident
Song Description
Gives a clear, mournful series of whistled notes, evenly spaced and carrying well through dense forest. Phrases may accelerate slightly or descend in pitch, repeated at dawn and dusk. Calls include soft, single whistles and gentle contact notes.
Plumage
Olive-brown upperparts with a slightly rufescent crown; buff underparts heavily marked with bold black spots and streaks. Throat pale with fine dark mottling; face shows a narrow, pale supercilium and dusky auriculars. Short tail, rounded body, and relatively long legs typical of antpittas.
Diet
Feeds primarily on arthropods gleaned from leaf litter, including beetles, ants, termites, spiders, and orthopterans. Will probe among roots and overturn leaves with quick bill jabs. Occasionally takes small vertebrates such as tiny frogs or lizards. May sporadically attend army-ant swarms but is not an obligate follower.
Preferred Environment
Forages on the shaded forest floor of mature terra firme with dense understory. Most active along quiet trails, root tangles, and fallen logs where leaf litter accumulates. Avoids open areas and heavily flooded forest.
