Buckley's forest falcon (Micrastur buckleyi), also called lesser collared forest-falcon and Traylor's forest-falcon,[3] is a species of bird of prey in subfamily Herpetotherinae of family Falconidae, the falcons and caracaras.

Their iris is dark brown, their cere, lores, and bare skin around the eye are dull greenish, and their legs and feet are yellowish.

[7] Sightings of Buckley's forest falcon fledglings suggest that its breeding season includes April to early August.

Nothing else is known about its breeding biology though it is assumed to nest in tree cavities like other Micrastur forest falcons.

[8] The IUCN has assessed Buckley's forest falcon as being of Least Concern, though it has a limited range and an unknown population size that is believed to be decreasing.

"Evidence suggest that species is not immediately threatened; however, at least in part of range, habitat is in process of being cleared.
