The original female disappeared in 1996 but, by then, there was a small hybrid population of about a dozen birds. These birds and their descendants continue to exist on the island.

There is some molecular support for suggesting that their closest relatives are the large lyrebirds. As their name implies, treecreepers forage for insects and other small creatures living on and under the bark of trees, mostly
