Southern African birds are intra-African migrants, arriving in their breeding grounds in September and October.
There are two subspecies:
Forest, woodland, thickets, and plantations.
Generally solitary. Seldom seen, even when calling; usually perched high in a tree.
Forages, mainly for caterpillars, in the canopy; sometimes takes prey aerially or on the ground. Also eats other insects, birds eggs and nestlings.
The song is distinctive: The male has a loud, monotonous whistle "hoop-hoo whoooo"; also a wild, whirling "whirly, whirly, whirly,.....". In southern Africa call from September to December.
