Common Name: Brown or American Treecreeper
Scientific Name: Certhia americana

Size: 5-6 inches (12-14cm)

Habitat: Throughout the United States and Pacific Northwest. Found in conifer and mixed conifer forests.

Status: Least Concern. Global Population: 5,400,000 Mature individuals. Widespread and abundant, but habitat loss and degradation is considered a threat to the species in Kentucky, Illinois, Indiana, Ohio, New Jersey, New York, Idaho, and Montana.

Diet: Insects, spiders, occasionally seed. Forages on tree trunks, creeping, methodically spiraling upward.

Breeding: The nest is cup of spider silk and cocoon cases anchored behind a piece of loose tree bark. It is lined with mosses, feathers and leaves. Five to six eggs are laid. While the sexes look the same, male are slightly larger and have slightly longer beaks than females. Brown Creeper nests in Arizona often have two openings, one that serves as an entrance and the other as an exit. Entrances face downward and exits face upward.

Cool Facts: The Brown Creeper is a camouflage expert. By laying flat on the bark of a tree in patterning helps it to blend in with trees, thus hiding from predators.

While the Brown Creeper bears an extremely close physical resemblance to the Old world cousins, Eurasian Treecreeper or Short-toed Treecreeper, it is a separate species. At one time, the Brown Creeper considered the same species as the Eurasian Treecreeper. In studies, including experiments having the Eurasian and Brown sing to each other, it was found that they do not respond to each other's songs, thus supporting the theory of them being separate species.
