The White-throated Treecreeper - Cormobates leucophaeus - has a mid to dark grey upper back, grey rump. White throat and breast. Flanks and belly are striped, undertail is barred. In flight a pale buff wing bar shows across both upper wing and underwing; the edge of this bar is visible on the folded wing. Bill is slender, tapering to a fine point and slightly down turned. Grows to 14 to 16.5 centimetres long.
Females have an orange-red spot on the side of the neck at the edge of the white throat.
While foraging moves rapidly up tree trunks to the lower branches probing at the bark as it goes, then flies directly to the base of a nearby tree and repeats the procedure on that tree. Rarely hunts on the ground. Usually solitary; in pairs or family parties in the breeding season. The name 'treecreeper' seems inappropriate for a bird which moves so rapidly and directly.
Lives in rainforest, open forest and woodland as well the forested river margins of drier regions. Also lower scrub of banksia woodland, mallee and brigalow. Common and sedentary in habit.
