Bolivian tyrannulet

Attila bolivianus

The Bolivian tyrannulet (Attila bolivianus) is a small, insect-eating bird found in the Andean and Amazonian regions of Bolivia and adjacent areas of Peru and Brazil. It has a distinctive olive-green plumage with a yellow belly and a black mask around its eyes. This species is known for its melodious and repetitive song, often heard in the dense undergrowth of humid forests. Bolivian tyrannulets are typically found in the midstory and understory of montane and lowland forests, where they forage for insects and small invertebrates. Despite being relatively widespread, their population status is not well-documented, and they are currently classified as Least Concern by the IUCN.

Habitat: Montane and lowland forests
