Common Names: Brown creeper, American treecreeper
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 tail. The male creeper has a slightly larger bill than the female.
They forage on tree trunks and branches, typically spiraling upwards from the bottom of a tree trunk, and then flying down to the bottom of another tree. They creep slowly with their body flattened against the bark, probing with their beak for insects. They will rarely feed on the ground. They mainly eat small arthropods found in the bark, but sometimes they will eat seeds in winter.
