Some individuals (more females than males) have rufous and brown barring on the underparts. The bill, legs and feet are black, and the eyes brown. 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.
