The tiny Brown Creeper is named for its distinctive feeding behavior. Starting at the bottom of a tree, it creeps up; when it reaches the top of the tree, it flutters down to the base of the next and begins circling up again. It never descends trees head-first like a nuthatch—this bird is always moving upward!
Like the endangered Northern Spotted Owl and Marbled Murrelet, the Brown Creeper favors mature forests with large trees. Habitat loss and fragmentation have caused the species to decline in many parts of its range. It is also a frequent victim of window collisions.
