Conservation status Declined as a breeding bird in much of eastern United States with cutting of forests; nests mainly in mature forest, not young second growth. Still common locally in north and west.
Family Creepers
Habitat Woodlands, groves, shade trees. Breeds in mature forest, either coniferous or deciduous, with many large trees, ranging from mountain pine woods to lowland swamp forest. In migration, may be found in any habitat with at least a few good-sized trees, even suburbs or city parks.
Looking like a piece of bark come to life, the Brown Creeper crawls up trunks of trees, ferreting out insect eggs and other morsels missed by more active birds. It is easily overlooked until its thin, reedy call gives it away. Reaching the top of one tree, it flutters down to the base of another to begin spiraling up again. Creepers even place their nests against tree trunks, tucked under loose slabs of bark, where they are very difficult to find.

Feeding Behavior

Does almost all foraging on trunk and limbs of trees, climbing slowly with tail braced against surface, examining bark visually and probing in crevices. Occasionally forages on ground or snow.


5-6, sometimes 4-8. Whitish, dotted with reddish brown. Incubation is by female, about 14-17 days. Male may feed female during incubation. Young: Both parents bring food for nestlings. Young leave nest about 13-16 days after hatching.


Both parents bring food for nestlings. Young leave nest about 13-16 days after hatching.


Mostly insects. Feeds on a wide variety of insects, especially insect eggs and pupae hidden in bark; also weevils and other beetles, true bugs, leafhoppers, scale insects, aphids, caterpillars, ants, and many others. Also feeds on spiders and pseudoscorpions. Eats some seeds, and will feed on suet or peanut-butter mixtures.


Male defends nesting territory by singing. In courtship, male may perform rapid twisting flight among trees; may pursue female in the air and around tree trunks. Nest: Usual nest site is behind a large strip of bark still attached to a tree; occasionally in cavity in tree. May be at any height from very low to 50' or more above ground. In typical sites, nest is a shallow half-cup, closely fitting the available space behind the bark slab. Nest (built by female, with male bringing some material) is made of twigs, bark strips, moss, leaves, lined with finer materials.
