Troglodytes hiemalis

The winter wren (Troglodytes hiemalis ) is a very small North American bird and a member of the mainly New World wren family Troglodytidae. It was once lumped with the Pacific wren (Troglodytes pacificus ) of western North America and the Eurasian wren (Troglodytes troglodytes) of Eurasia under the name winter wren.

It breeds in coniferous forests from British Columbia to the Atlantic Ocean. It migrates through and winters across southeastern Canada, the eastern half the United States and (rarely) north-eastern Mexico. Small numbers may be casual in the western United States and Canada.

The scientific name is taken from the Greek word troglodytes (from "trogle" a hole, and "dyein" to creep), meaning "cave-dweller", and refers to its habit of disappearing into cavities or crevices while hunting arthropods or to roost.

Appearance

Small tail is often cocked above its back, and short neck gives the appearance of a small brown ball. Rufous brown above, grayer below, barred with darker brown and gray, even on wings and tail. The bill is dark brown, the legs pale brown. Young birds are less distinctly barred. Most are identifiable by the pale "eyebrows" over their eyes.

Distribution

Geography

Continents
Biogeographical realms

The winter wren nests mostly in coniferous forests, especially those of spruce and fir, where it is often identified by its long and exuberant song. Although it is an insectivore, it can remain in moderately cold and even snowy climates by foraging for insects on substrates such as bark and fallen logs.

Its movements as it creeps or climbs are incessant rather than rapid; its short flights swift and direct but not sustained, its tiny round wings whirring as it flies from bush to bush.

At night, usually in winter, it often roosts, true to its scientific name, in dark retreats, snug holes and even old nests. In hard weather it may do so in parties, either consisting of the family or of many individuals gathered together for warmth.

Diet and Nutrition

For the most part insects and spiders are its food, but in winter large pupae and some seeds are taken.

Mating Habits

The male builds a small number of nests. These are called "cock nests" but are never lined until the female chooses one to use. The normal round nest of grass, moss, lichens or leaves is tucked into a hole in a wall, tree trunk, crack in a rock or corner of a building, but it is often built in bushes, overhanging boughs or the litter which accumulates in branches washed by floods. Five to eight white or slightly speckled eggs are laid in April, and second broods are reared.
