Physical description Click here for a physical description White-browed Treecreepers have a grey cap and neck, dark greyish-brown back, dark-brown upperwings with a rufous wing patch, a white throat, grey chest and heavily streaked belly. The vent is white with dark-brown barring. They have streaked black and white ear patches. The eyebrows are white. Females have some inconspicuous rufous chest marks and rufous stripes above the white eyebrows, which are narrower than those of males. The irises of both sexes are dark, the bill, legs and feet are all dark-grey. Twitcher's tip Compared to Brown Treecreepers, White-browed Treecreeper have a lighter (white) eyebrow. All other Australian species of treecreepers are noticeably darker.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the White-browed Treecreeper is available HERE . NB: Reports on ebird of birds submitted by birdwatchers from the Australian Outback tend to be clustered along roads and public areas such as camp grounds; in such cases their distribution is not a good representation of the overall distribution of the species. There are two races of White-browed Treecreepers, both of which are endemic to Australia. Both races inhabit the interior of the Australian continent. Race "affinis" is found in the Paroo-Darling catchment in southern inland QLD and North-West NSW and into SA, up to about Lake Eyre. To the West of Lake Eyre, into the North-West corner of SA, into the southern part of the NT (up to about Alice Springs) and into parts of inland WA, North of the Nullarbor and towards Lake Austin, WA, race "superciliosa" is found. White-browed Treecreepers live in semi-arid to arid environments, with a preference for acacia woodland (such as e.g. Acacia cambagei), casuarinas and Cypress pines.

Sightings Click here for sighting information Race "affinis" B. Hensen reports spotting a White-browed Treecreeper, race "affinis", at Bowra Wildlife Sanctuary, QLD, in October 2012. F. Japp reports spotting a White-browed Treecreeper, race "affinis", at Murray Sunset NP, VIC, in May 2014. M. Eaton found White-browed Treecreepers, race "affinis", at Eulo, QLD, in June 2020.

ADULT

PAIR

Many bird species exhibit sexual dimorphism, i.e., male and female have differing appearances which can be quite subtle.
Female White-browed Treecreepers, right, have chestnut markings on the chest and a prominent chestnut bar above the white supercilia ("eyebrows"); both of these are absent in males.
