The brown treecreeper is semi-terrestrial and can live in more open woodland habitats, [1] but is still sensitive to the loss of its habitat. [3] The Australasian treecreepers are essentially non-migratory, although there are distinct differences in the dispersal of young birds after fledging, especially between the two genera.
The basic colouration of the stocky body is dark-brown. The large protruding eyes are round and reddish-brown to red. The pronotum is hairy, arched up and pulled back in a long, wave-shaped extension above the wings, with two sharp, ear-shaped lateral protrusions (hence the Latin name cornutus, meaning "horned"). The legs are very short.
Treehoppers, due to their unusual appearance, have long interested naturalists. They are best known for their enlarged and ornate pronotum , expanded into often fantastic shapes that enhance their camouflage or mimicry , often resembling plant thorns (thus the commonly used name of "thorn bugs" for a number of treehopper species).
Coenraad Jacob Temminck and Meiffren Laugier de Chartrouse described the brown treecreeper in 1824, and it still bears its original name today. [3] It is one of six species of treecreeper found in Australia, and is most closely related to the rufous treecreeper (Climacteris rufus) of Western Australia and the black-tailed treecreeper (C. melanurus).
The Atlas of Australian Birds is a major ongoing database project initiated and managed by BirdLife Australia (formerly the Royal Australasian Ornithologists Union) to map the distribution of Australia's bird species. BirdLife Australia is a not-for-profit bird research and conservation organisation. There have been other bird atlases produced ...
There have been three comprehensive accounts: the first was John Gould's 1840s seven-volume series The Birds of Australia, the second Gregory Mathews, and the third was the Handbook of Australian, New Zealand and Antarctic Birds (1990-2006). The taxonomy originally followed is from Christidis and Boles, 2008. [1]

They feed singly or in pairs during the breeding season, but have been recorded as joining mixed-species feeding flocks in the winter months. [11] The majority of foraging occurs on Eucalyptus , with other trees being used much less frequently; among the eucalyptus, trees from the subgenus Symphyomyrtus are preferred.
