Description
Males are larger than females in wing length, weight, and bill-size. Males have black throats, while females have olive green throats, and both sexes have bold black and white markings on the face.
Behaviour
It feeds mainly on insects, spiders and, sometimes, particularly during the breeding season, young birds. Thistle seeds are also taken. It has a parrot-like bill, used for distinctive bark-stripping behaviour, which gains it access to invertebrates. The bird is unobtrusive, and the sound of the bark strips being torn off trees provides an indication of its presence. It nests high in a eucalyptus tree, in a fork of a branch, both sexes sharing the incubation and the rearing of the young. There may be two broods.
