The brown creeper is a small, long-tailed songbird with a down-curved, pointed bill. Its brown mottled upperparts blend in easily with tree bark, while its underparts are white. Both sexes look virtually identical. Its call is loud and piercing, whichhelps make its otherwise inconspicuous appearance known. Though it is not completely certain, males and females most likely form monogamous pairs. When approaching a potential mate, males fly in a spiral; they also compete for territory by engaging in singing competitions. Their breeding season extends from April to July, where they typically nest on dead or dying trees where loose bark is abundant. Their nests are usually nestled between the loose, dead bark and the tree trunk. Females lay around 5-6speckled white eggs, which she incubates for between 13-17 days. Both parents feed the fledglings.
