A sooty brown raptor, appearing black in the field, with variable amounts of white on the throat and belly. At close quarters, white legs, eyelids and nape patches are distinctive.
Juveniles are dappled brown with more white plumage than shows on adults.
Tropical forest and woodlands with adjacent open areas, sometimes occurs close to towns.
Crepuscular and nocturnal, roosting in thick foliage during the day.
The diet includes mainly bats, also small birds and insects. The large gape allows them to swallow small bats whole.
The nest is built from sticks and the eggs are incubated by the female for about 28 days. Both parents feed the young which fledge 30-45 days later.
