Length: 5 in. (13 cm)
The distinctive behavior of creeping up the trunks of large trees in a spiral is unlike any other species of bird in North America. It uses the curved bill to probe for insects and spiders from loose bark and small cavities but occasionally eats seeds. The nest is made of spider silk, moss and twigs and slung in loose bark or a shallow cavity, usually on the trunk of a conifer. The four-digit banding code is BRCR.
