The Brown Treecreeper (Climacteris picumnus) is the largest species of Australasian treecreeper. It is endemic to forests and woodlands of the Great Dividing Range in eastern Australia. As the name implies, its colour is pale brown to grey-brown, with black streaking on the underparts and black bars on the undertail, with almost no sexual dimorphism. Although the International Union for Conservation of Nature considers the Brown Treecreeper a "Least Concern" species, one subspecies found in New South Wales is rated threatened by Australian authorities.Photo: Fir0002
