There are 7 species
of Australasian treecreeper
in the passerine
bird family Climacteridae
. They are medium-small, mostly brown birds with patterning on their underparts, and all are endemic to Australia-New Guinea
As their name implies, treecreepers forage for insects and other small creatures living on and under the bark of trees, mostly eucalypts
, though several species also hunt on the ground, through leaf-litter, and on fallen timber.
Australasian treecreepers nest
in holes in trees. The species in the family hold breeding territories
, although the extent to which they are defended and last varies. Some species, such as the Red-browed Treecreeper
and the Brown Treecreeper
are cooperative breeders, others, like the White-throated Treecreeper
are not. The cooperative breeders form groups or a single breeding pair as well as up to three helpers
, which are usually the young males of previous pairings. Helpers assist with the construction of the nest, feeding of the incubating female and feeding and defending the young.
