Range & population Accipiter collaris is known from a few localities on the west and east slopes of the Andes from south-west Venezuela (Mérida, Táchira), through Colombia and Ecuador, with a recent range extension of 1,500 km to south Peru⁵. Although occasionally relatively abundant^1,5, it is usually rare and highly sensitive to human disturbance⁴.

Ecology: It occurs in forest and forest edge, mostly subtropical and moist or wet, at 1,700-1,950 m in Peru² and at 600-1,800 m in Colombia^3,5.

Threats Forest in many parts of its range has suffered major losses, primarily due to agricultural expansion.

Conservation measures underway None is known.

Conservation measures proposed Study its ability to persist in degraded and fragmented habitats. Survey and attempt to estimate global population. Extend protected areas network to include further core areas of remaining habitat.
