What does it look like?
Description
The Grey Shrike-thrush is a rather drab coloured bird, although the plumage varies throughout its extensive range. Birds are mostly grey in the east, with an olive-grey back, and pale grey-white cheeks and underparts. In the north, the plumage is predominantly brown, and western birds are grey with buff underparts. Adult males are browner on the mantle than the female and young birds have varying amounts of rufous on the cheeks and wings.
Where does it live?
Distribution
Grey Shrike-thrushes are found in all but the most arid regions of Australia and Tasmania, as well as on the larger offshore islands and in southern New Guinea.
Habitat
The Grey Shrike-thrush is found in forests and woodlands. It is a common and familiar bird, although some decrease in numbers has been noted around human habitation, particularly in the west of its range.
What does it do?
Feeding
The Grey Shrike-thrush searches for food on the ground, generally around fallen logs, and on the limbs and trunks of trees. It has a varied diet consisting of insects, spiders, small mammals, frogs and lizards, and birds' eggs and young, and some birds have been observed feeding on carrion. Fruits and seeds may also be eaten on occasion.
Breeding
Grey Shrike-thrush pairs generally remain together for life and inhabit the same areas throughout this time. Breeding territories of up to ten hectares are maintained. The nest is a cup-shaped structure of dried vegetation, and may be constructed in the same site year after year. Both birds share the nest-building and incubation duties, and both care for the young birds.
