Species Description

The Brown Thornbill is a small, active songbird found throughout eastern and southeastern Australia, including Tasmania and King Island. It thrives in a wide range of habitats, from dense forests and woodlands to heathlands, shrublands, and even well-vegetated urban parks.

Fun Facts

Brown Thornbills are skilled mimics, able to imitate alarm calls of other birds to deter predators from their nests.

Brown Thornbills feed mainly on insects, spiders, and other small invertebrates, but may also take seeds, fruit, and nectar. They are usually seen in pairs or small family groups and form lifelong pair bonds, defending territories year-round. They breed from july-january and the domed nest, built by the female, is placed low in dense vegetation and constructed from grasses, bark, moss, and spider webs, with a hooded entrance. The typical clutch is three eggs, and both parents help incubate for about 19 days and care for the young, which fledge after around 16 days. They may raise two broods per year.

Brown Thornbills are found within about 3 km of the Australian east and southeast coasts, including the Blue Mountains, the Great Dividing Range, Tasmania, and King Island. They inhabit forests, rainforests, woodlands, heathlands, shrublands, and dense undergrowth along rivers and creeks. Look for them in the lower shrub layers and understorey, where they forage actively, often in small groups or mixed flocks.
