The brown treecreeper (Climacteris picumnus) is the largest Australasian treecreeper.

Found in a diverse range of habitats varying from coastal forests to mallee shrub-lands, the brown treecreeper often occupies eucalypt-dominated woodland habitats up to 1,000 metres (3,300 ft), avoiding areas with a dense shrubby understorey.
Coenraad Jacob Temminck and Meiffren Laugier de Chartrouse described the brown treecreeper in 1824, and it still bears its original name today. It is one of six species of treecreeper found in Australia, and is most closely related to the rufous treecreeper (Climacteris rufus) of Western and Southern Australia, and the black-tailed treecreeper (C. melanurus). All three occupy similar savannah and open woodland habitat, and have a sexually dimorphic marking on the upper breast or throat (black... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Brown Treecreeper is recorded against all the birds logged in Hattah-Kulkyne National Park (140 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
