Lives in damp, dense forests, humid tropical rainforests and eucalyptus woodlands with underbrush.

During non-breeding season, they may live in open drier areas, secondary forests and large gardens.

Found mainly around the South-east of Australia, also in the Atherton Tablelands, and in Queensland.

Nest is a large bowl-shaped structure, made with bark strips, twigs, stems, grasses and leaves. It is lined with moss, fine grass and rootlets, and may also be covered with moss.

The female lays 2 - 3 pale eggs, green or bluish-green, with fine markings. Incubation lasts about 14 days.
