If a Bassian Thrush is disturbed it often runs a short distance and then freezes, relying for defence on the camouflage of its mottled plumage against the leaf-litter of the forest floor.
Identification
The Bassian Thrush is a secretive bird. Its plumage is mottled brown to olive-brown, heavily scalloped with black crescent-shaped bars on the back, rump and head. The paler underparts all have brown-black scalloping. It has a white eye-ring. In flight the Bassian Thrush shows a broad dark diagonal bar across the white underside of its wing.
Habitat
Damp, densely forested areas and gullies are favoured by the Bassian Thrush, usually with a thick canopy overhead and leaf-litter below.
Distribution
The Bassian Thrush is found predominantly around the south-east of Australia, and also in the Atherton Tablelands, Queensland.
Seasonality
Resident, probably sedentary.
Feeding and diet
The Bassian Thrush feeds on the ground, scratching under the leaf-litter for small invertebrates.
Communication
The Bassian Thrush can be heard mainly at dawn or in dull weather, its song being three notes: the first steady, the second rising briefly, and the third steady.
Breeding behaviours
The Bassian Thrush builds a large, deep, cup-shaped nest in a major tree fork or in a depression on top of a stump. The nest may be quite low or up to about 15 m above the ground. Both parents care for the young.
- Breeding season: June to February, also recorded in April
- Clutch size: Two to three.
- Incubation: 14 days
- Time in nest: 14 days
Conservation status
The Bassian Thrush is adversely affected by clearing of densely vegetated habitats.
