An arboreal bird of northern Australia, with a striking black-and-white head and a deep hooked bill.
The northern form has black-and-white head markings and a black crest, a green back, and yellow underparts. Males have a black throat, while females have an olive-green throat; the bill is deep and strongly hooked.
In northern Australia it has been recorded in woodlands mainly dominated by eucalypts. The northern form is thought to search among the foliage, branches, trunks, and bark of eucalypts and other trees for invertebrates.
