This is a monotypic species[1].
Formerly placed in the genus Leucopternis.

Habitat

Canopy and edges of humid mountain forests. Rarely seen on Colombian coastal plains.

Behaviour

They sit on exposed perches at forest edges; usually alone though sometimes in pairs or small groups.

They soar high above the forest, calling frequently and performing aerial displays.

Diet

Their diet consists of snakes, frogs, large insects and crabs; occasionally mammals and birds. In forest interiors they ambush their prey when it comes close to their perch (a practise known as still-hunting).
