Threat Summary:

There is evidence of a population decline although overall numbers are not known. Threatened by deforestation: is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined in its range by 4.6% over the past three generations. Therefore, it is tentatively suspected that this may have led to a 1-19% decline in the species’ population over the same period.

A.m. mercenarius: Mountains of N Bolivia, in La Paz, Cochabamba and W Santa Cruz, north to N Peru and W Ecuador.
A.m. canipalliata: Both slopes of Andes in W Ecuador to W Colombia, north to Cundinamarca and SW Antioquia; also probably Sierra Nevada de Santa Marta, Sierra de Perifa and mountains of NW Venezuela.

Habitat:

Found in hill and mountain forest in upper tropical, subtropical and temperate areas. Includes open woodland with large trees, open forest on ridges and to treeline in wooded valleys and ravines in paramo zone. 800-1600 m (2624-5248 ft).
