Genus Certhia
California creeper - Adults are brown on the upperparts with light spotting, resembling a piece of tree bark, with white underparts. They have a long thin bill with a slight downward curve and a long tail. The male creeper has a slightly larger bill than the female. The Brown creeper is 11.7-13.5 cm long .
Short-toed Treecreeper - Short-toed Treecreeper is one of a group of four very similar Holarctic treecreepers, including the closely related North American Brown Creepers, and has five subspecies differing in appearance and song. Like other treecreepers, Short-toed is inconspicuously plumaged brown above and whitish below, and has a curved bill and stiff tail feathers. It is a resident in woodlands throughout its range, and nests in tree crevices or behind bark flakes, laying about six eggs. This common, unwary, but inconspicuous species feeds mainly on insects which are picked from the tree trunk as the treecreeper ascends with short hops.
Brown-throated Treecreeper - It is found in Bhutan, China, India, Laos, Burma, Nepal, Thailand, and Vietnam.
Eurasian Treecreeper - The Eurasian Treecreeper or Common Treecreeper, Certhia familiaris, is a small passerine bird also known in the British Isles, where it is the only living member of its genus, simply as Treecreeper. It is similar to other treecreepers, and has a curved bill, patterned brown upperparts, whitish underparts, and long stiff tail feathers which help it creep up tree trunks. It can be most easily distinguished from the similar Short-toed Treecreeper, which shares much of its European range, by its different song.
Bar-tailed Treecreeper - The Bar-tailed TreeCreeper has a flecked or striped feather pattern, usually in black, brown, white and red hues. This coloration allows the Tree-Creeper to blend in with its forest surroundings quite well.
Certhia hodgsoni - Hodgson's Treecreeper, Certhia hodgsoni, is a small passerine bird from the southern rim of the Himalayas. Its specific distinctness from the Common Treecreeper was recently validated.
Certhia tianquanensis - The Sichuan Treecreeper is a rare species of bird in the treecreeper family, Certhiidae.
