Brown Creeper Certhia americana
Order: PASSERIFORMES Family: Creeper (Certhiidae)
Description: The creeper has a long stiff, pointed tail to help it climb tree trunks, and a long down curved bill to probe insects from bark. Its brown back feathers with buff white streaks, white eyebrow feathers, and white belly feathers make them nearly indistinguishable from a piece of bark.
General: The cryptic Brown Creeper usually hangs out in old-growth forests and will nest behind loose bark of a dying tree. The base of the nest is attached to the bark with webbing from cocoons or spider egg cases, and then a cup is made of fine pieces of bark, fibers, leaves, mosses, and feathers.
Behavior: Brown Creepers are the only tree creepers in North America. Feeding mainly on invertebrates found on tree trunks, they start at the bottom of a tree, spiral upward, then float down to the base of the next tree and begin again. A group of creepers are collectively known as a "sleeze" and a "spiral" of creepers.
