The Tasmanian Thornbill (Acanthiza ewingii) is a small bushland member of the Acanthizidae (Australian warbler) family, endemic to Tasmania and the Bass Strait Islands.

There are five principal, physical, differences to distinguish between the two species: The Tasmanian thornbill is endemic to Tasmania and the Bass Strait Islands and is a common resident of rainforests, wet forests, and scrublands.

It shares much of its range with the brown thornbill, but tends to occupy the wetter areas of the habitat, often choosing to live in dense scrub around wet gullies rather than the drier, more open slopes.

It is typically arboreal, and will forage at all levels of the forest including the ground, leaves, and the bark of trunks, branches, and twigs.

[5] Tasmanian Thornbills typically breed from September to January, and will build a small, neatly rounded, domed nest in low, dense vegetation.
