What the Brown Creeper sounds like

The Brown Creeper is a diminutive woodland bird with remarkable camouflage that makes it appear like 'a fragment of detached bark that is defying the law of gravitation by moving upward.' Its streaked brown and buff upperparts blend seamlessly with tree trunks, while its white underparts are usually hidden against the bark. The brownish head features a broad, buffy stripe over the eye (supercilium). Its most distinctive features are its slender, downcurved bill and its stiff, spine-tipped tail that it uses as a prop when climbing.

His song is a jumble of high, thin notes that lasts up to 1.5 seconds, sometimes likened to singing the phrase 'trees, beautiful trees.' Males may join single songs together two or three times in a row. Often written as “trees, beautiful trees”.
Don't confuse with:The White-breasted Nuthatch — similar size but chunkier with straight bill, moves headfirst down trees.

Where you'll hear it

This species has a strong affinity for mature forests with large trees, which provide both foraging opportunities and nesting sites. It requires large live trees with deeply furrowed bark for foraging (which harbor the highest densities of insects) and large dead or dying trees with loose bark for nesting. While it breeds primarily in coniferous or mixed forests, during winter it becomes more adaptable, appearing in deciduous woodlands, parks, suburbs, and even city areas with sufficient large trees.

Breeds in spring and summer, with males establishing territories through song. In fall and winter, becomes more social, often joining mixed-species flocks. Unlike many birds, Brown Creepers are active throughout the day in all seasons, continuously foraging to meet their energy needs.
