Animal Species:Bassian Thrush

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.

Distribution

The Bassian Thrush is found predominantly around the south-east of Australia, and also in the Atherton Tablelands, Queensland.

Habitat

Damp, densely forested areas and gullies are favoured by the Bassian Thrush, usually with a thick canopy overhead and leaf-litter below.

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.

Mating and reproduction

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.
