The large-billed antwren is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia and Brazil.
Region
South America
Typical Environment
Occurs primarily in the Cerrado and dry forest mosaics of central Brazil, extending into eastern Bolivia. It favors gallery forests, dry to semi-deciduous woodlands, and scrubby edges near watercourses. Birds typically forage from the lower midstory to the subcanopy, especially along forest edges and in secondary growth. It is a year-round resident throughout its range and adapts reasonably well to lightly disturbed habitats, provided some woody cover remains.

The large-billed antwren is a small, canopy-leaning antbird of the Brazilian Cerrado and adjacent regions of eastern Bolivia. It often forages in pairs and may join mixed-species flocks, keeping in near-constant motion as it gleans insects. Its name refers to its proportionately long, sturdy bill used to probe leaves and bark. Duet singing between mates is common and helps maintain territories year-round.
Temperament

short rapid wingbeats
Social Behavior
Typically found in pairs or small family groups, maintaining territories year-round. Frequently joins mixed-species flocks while foraging through the midstory. Nests are small, suspended cups placed low to mid-height in dense foliage, and both parents participate in care.

Song Description
Song is a fast, high-pitched series of thin trills and whistles, often delivered as coordinated duets between mates. Calls include sharp chips and sibilant notes used to keep contact while moving through foliage.
