The Brown Creeper is a small songbird. 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. Breeding season typically begins in April. The female will make a partial cup nest either under a piece of bark partially detached from the tree, or in a tree cavity. It will lay 3-7 eggs, and incubation lasts approximately two weeks. Both of the parents help feed the chicks.
