Physical description Click here for a physical description Brown 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 light- and mid-brown ear patches. The eyebrows are greyish-brown. Male Brown Treecreepers have some inconspicuous black and white chest marks while those of females are chestnut and white. The irises of both sexes are dark, the bill, legs and feet are all dark-grey. Race "melanotus" has by far the darkest upperparts. Juveniles have less colour contrast in their facial markings, with buff supercilia, and they lack the chest marks. Twitcher's tip Compared to White-browed Treecreepers, Brown Treecreepers have a darker (greyish brown) 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 Brown Treecreeper is available HERE . Brown Treecreepers are endemic to Australia. Together, the three races of Brown Treecreeper populate large parts of QLD, NSW, VIC and the south-eastern tip of SA. Race "melanotus" is found in northern QLD, in a region from near the tip to just southward of the base of Cape York peninsula. Further South, beyond a line connecting Charters Towers and Townsville, QLD, throughout the rest of the total range (roughly sub-tropical QLD, inland NSW and the SE corner of SA), nominate race "picumnus" is found, except: In the NSW and VIC hills of the Great Dividing Range there is race "victoriae". Brown Treecreepers can be found in open forests and open woodland. They tend to stick to the edges of open areas, such as e.g. along rivers or creeks, clearings or forest edges.

Sightings Click here for sighting information Race "picumnus" A Brown Treecreeper, race "picumnus", was first spotted by us in the Flinders Ranges, SA, in March 2008. M. Mearns spotted Brown Treecreepers, race "picumnus", at Currawinya NP, near Hungerford, QLD, in October 2012. Next, race "picumnus" was found in the Pilliga West SCA, 25 km South of Pilliga, NSW, in December 2015. They were also found by V. Collins and ourselves at Merriwindi SCA, near Kenebri, NSW, in January 2021. We found Brown Treecreepers, race "picumnus", at Culgoa Floodplain NP, QLD, in September 2017. M. Eaton reports finding Brown Treecreepers, race "picumnus", at Bowra Wildlife Sanctuary, near Cunnamulla, QLD, in September 2017. They were found again at the same location in June 2022. Race "victoriae" Brown Treecreepers, race "victoriae", came to the place where we lived until 2006, 20 km South of Narrabri, NSW, quite regularly. We also saw them in the adjacent bushland, in Jack's Creek State Forest. Brown Treecreepers, race "victoriae", are seen and heard by us regularly in the area of Deriah Aboriginal Area, 30 km East of Narrabri, in the years 2007 to date. Together with White-throated Treecreepers, they are the most common species of treecreeper in the area. They do not come to open farm country, only 10 km further West. Brown Treecreepers, race "victoriae", have been found by us in various other locations in inland NSW, such as e.g. in October 2005 near Bingara, NSW, then 30 km North of Coonabarabran in April 2006 and 50 km North-East of Narrabri in September 2008. They are also found regularly in the ara of Maules Creek and (still) Leard State Forest. R. Plumtree reports finding Brown Treecreepers, race "victoriae", nesting near Ensay South, East Gippsland, VIC, in October 2015. Race "melanotus" J. Boettcher, FNQ Nature Tours reports finding Brown Treecreepers, race "melanotus", at the Tropical Wetlands Forever Wild Shared Earth Reserve, Cape York peninsula, QLD, in December 2019.
