The Bassian Thrush (Zoothera lunulata), commonly known as the Olive-tailed Thrush, is a medium-sized mostly insectivorous thrush found predominantly in southeastern Australia and Tasmania. The thrushes range from 27 to 29 cm, averaging about 28 cm and 100 grams.
It is estimated that the rangewide population is large, though no official count has ever been established.
The Bassian Thrush lives in shrubland, forests, and rainforests. It is non-migratory. Though affected by human destruction of their natural habitats, its range is so large that the impact is negligible.
The thrush ranges in color from brown to an olive color, with a white ring arounds its eyes and black bars on its back, rear, and head. Its underbody is paler, with dark scalloping, and its wings have a dark bar running the length of the underside
