The winter wren is a very small North American bird and a member of the mainly New World wren family Troglodytidae. The species contained the congeneric Pacific wren of western North America and Eurasian wren (Troglodytes troglodytes) of Eurasia until they were split in 2010.
Region
Eastern North America
Typical Environment
Breeds across boreal and mixed coniferous-deciduous forests of Canada and the northeastern United States, extending along the Appalachian Mountains. In winter it moves south into the eastern and southeastern U.S., occupying dense thickets, ravines, and forested wetlands. It favors shaded, humid microhabitats with abundant fallen logs, root wads, and moss. Occasional individuals winter in sheltered coastal or urban green spaces where dense understory persists.

One of the smallest North American songbirds, the winter wren delivers an exceptionally loud, cascading song for its size. It creeps through tangled roots, logs, and mossy stream banks with its tiny tail usually cocked upright. In 2010 it was split from the Pacific wren (Troglodytes pacificus) and the Eurasian wren (Troglodytes troglodytes). It often nests in natural cavities or root tangles, with males building multiple ‘dummy’ nests.

Temperament
shy and secretive
Flight Pattern
short rapid wingbeats with low, darting flights
Social Behavior
Generally solitary and strongly territorial during the breeding season. Males often construct multiple nests; females select one and complete the lining. Nests are placed in cavities, root tangles, or crevices near the ground, often close to streams. Outside breeding, it may forage loosely near other small passerines but remains unobtrusive.
Migratory Pattern
Seasonal migrant
Song Description
A long, explosive cascade of rapid trills, tinkling runs, and buzzy notes delivered with remarkable volume. Calls include dry ticks and thin, high see notes used in contact and alarm.
Plumage
Dark, warm brown overall with dense, fine barring on wings, tail, and flanks; subtly mottled, with a slightly paler throat and belly.
Diet
Primarily small invertebrates such as beetles, ants, caterpillars, flies, and spiders. It also takes larvae and other arthropods gleaned from bark, moss, and leaf litter. In winter, it may supplement with small berries or seeds when insects are scarce.
Preferred Environment
Feeds close to the ground in dense undergrowth, among fallen logs, root masses, and stream-edge debris. Often probes into crevices, flips leaves, and searches mossy substrates in shaded, humid spots. Will use brush piles and stone walls in human-altered landscapes if cover is dense.
