[9] These ancient fossils all exhibit morphological features associated with scansorial (tree-trunk climbing), the primary mode of locomotion used during foraging by all extant species.

[9] The genus name ‘Climacteris’ is derived from the Greek term meaning ‘the rung of a ladder’, and refers to the groups tree-trunk climbing habits.

Adult male plumage is mostly dark grey above (crown, neck, rump and uppertail) excluding the mantle and scapulars of which are brown and black sub-terminal tail-band.

Juveniles differ from adults with pale grey bill and both facial patterning and ear-covert streaking duller and less distinct.

Flight pattern over longer distances is undulated, involving brief bursts of flapping within long glides, during which a buff wingbar is visible.

[2] White-browed Treecreepers inhabit a range of woodland and shrubland communities, dominated by either Acacia, Casuarina or Callitris species, with both dense and open understory's.

[10] White-browed treecreepers are sedentary, pairs or groups actively defending relatively large territories (averaging 8.4 hectares in some regions) throughout the year.

[2] The white-browed treecreeper is a scansorial (tree-trunk climbing) bark-foraging specialist, feeding upon a range of invertebrates (predominantly ants) gathered from on and beneath the bark of tree trunks and branches.

[2] White-browed treecreepers exhibit a number of morphological traits, primarily of the legs, feet and toes, thought to represent scansorial bark-foraging adaptations.

[2] Although up to two broods may be raised per season white-browed treecreepers have low productivity, with an average of only 1.58 young fledged per breeding unit annually.

Such threats have resulted in population declines and range contractions within some regions including Victoria, Australia, within which the species is now listed as Threatened under state legislation.
