The brown creeper (Certhia americana), also known as the American treecreeper, is a small songbird, the only North American member of the treecreeper family Certhiidae.
Adults are brown on the upper parts 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 stiff tail used for support as the bird creeps upwards. The male creeper has a slightly larger bill than the female. The brown creeper is 11.7–13.5 cm (4.6–5.3 in) long.
Its voice includes single very high pitched, short, often insistent, piercing calls; see, or swee. The song often has a cadence like; pee pee willow wee or see tidle swee, with notes similar to the calls.
Their breeding habitat is mature forests, especially conifers, in Canada, Alaska and the northeastern and western United States. They are permanent residents through much of their range; many northern birds migrate farther south to the United States. Brown creeper has occurred as a vagrant to Bermuda and Central America's mountains in Guatemala, Honduras and the northern cordillera of El Salvador. As a migratory species with a northern range, this species is a conceivable vagrant to western Europe. However, it is intermediate in its characteristics between common treecreeper and short-toed treecreeper, and has sometimes in the past been considered a subspecies of the former, although its closest relative seems to be the latter (Tietze et al., 2006). Since the two European treecreepers are themselves among the most difficult species on that continent to distinguish from each other, a brown creeper would probably not even be suspected, other than on a treeless western island, and would be difficult to verify even then.
