The Black-tailed Treecreeper hops up tree trunks while searching bark for invertebrates. It occurs in northern Australia, and the throat and chest pattern differs between the sexes.
The overall plumage is dark grey-brown. Males have a black-and-white streaked throat and upper chest; females have a white throat and chestnut breast streaks.
It hops rather than walks up trunks and searches bark for invertebrates. Observations also record nests in tree hollows lined with grass or similar material.
