This is a monotypic species1.

Habitat

Their preferred habitats are rain and open forests and forest edges, tall woodlands; adjacent open countryside and timbered watercourses.

Behaviour

Diet

Their diet consists mostly of birds and small mammals such as rabbits, possums, and bats. They also take snakes, lizards, frogs and insects.

Breeding

The grey and white morphs interbreed freely. They are monogomous and stay with their partner for life. Breeding takes place from July to December.

They build their nest in tall trees on a platform of sticks and twigs with a central depression lined with green leaves. The clutch consists of 2-3 eggs, which are incubated by the female for about 35 days. Chicks fledge 35-40 days after hatching. The male provides the food for the female to feed to the young.
