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.
Spotted on an alder tree at the Billy Frank Jr. Nisqually National Wildlife Refuge.
