birdin the thornbill family Acanthizidae. It is monotypicwithin the genus "Acanthornis", and is endemic to Tasmaniaand King Island in Australia. Its natural habitatis the temperate rainforest, " Nothofagus" beech forest and eucalyptwoodland. It is a small species that resembles the " Sericornis" scrubwrens (with which is was once placed).
The Scrubtit is 11-12 cm long and weighs around 10 g. The

The Scrubtit forages individually, in pairs or in small family groups near the ground in dense cover. It feeds on small invertebrates, particularly insects and their eggs. The species will associate with
mixed-species feeding flocks. The species is territorial and monogamous, with the breeding season lasting from September to January. The nest is a weaved globe with a side entrance, lined with feathers and fur, camouflaged and usually found between 1-3 m off the ground. The clutch size is usually 3 eggs, although no information exists about incubation or nestling times. Both parents feed the chicks in the nest. The species is victim to brood parasitismby Fan-tailed Cuckoos and Shining Bronze Cuckoos, and quolls also take eggs and nestlings.
The species has a restricted range but is not considered
threatenedby the IUCN. The subspecies found on King Island is considered critically endangered however. The species is sky and unobtrusive and is seldom observed by people.
