The Cuzco brushfinch is a skulking Andean understory bird, often detected by its sharp chips and mellow whistles rather than by sight. It is endemic to humid montane forests of southeastern Peru, especially around Cusco. Taxonomically it has been treated either as a distinct species or as a subspecies of the slaty brushfinch. It readily uses forest edges and bamboo tangles, which can help it persist in moderately disturbed habitats.

secretive and wary
Flight Pattern
short rapid wingbeats, low darting flights through cover
Social Behavior
Usually found in pairs or small family groups, keeping close to dense vegetation. Territorial during the breeding season, with both members of a pair staying in contact by calls. Nests are cup-shaped and placed low in thick shrubs or bamboo; both adults feed the young.

Resident
Song Description
Song is a series of mellow, clear whistles interspersed with thin trills, delivered from concealed perches. Calls include sharp chip or tseet notes used for contact and alarm.
