Winter Wren

The Winter Wren (Troglodytes hiemalis), a diminutive bird, is a marvel of the North American avifauna. This tiny, energetic bird, with its rufous brown plumage barred with darker shades, resembles a small brown orb. Its tail, characteristically cocked above its back, and its short neck contribute to its distinctive profile. The pale "eyebrows" over its eyes are a subtle but notable feature.

Identification Tips

When observing the Winter Wren, note its size, which ranges from 3.1 to 4.7 inches in length, with a wingspan of 4.7 to 6.3 inches. The bird's weight is a mere 0.3 to 0.4 ounces. Its upperparts are rufous brown, while the underparts are grayer, both barred with a mix of brown and gray. The bill is dark brown, and the legs are pale brown. Juveniles may exhibit less distinct barring.

Habitat

The Winter Wren is most at home in the coniferous forests, particularly those dominated by spruce and fir trees. It thrives in these environments, where it can be heard delivering its exuberant song.

Distribution

This species breeds from British Columbia to the Atlantic Ocean and migrates through and winters across southeastern Canada and the eastern half of the United States, with occasional sightings in northeastern Mexico.

Behaviour

The Winter Wren is a bird of constant motion, creeping and climbing through its habitat with more persistence than speed. Its flight is swift and direct, though not sustained, as it moves from one perch to another. In the winter months, it may roost in dark retreats, such as cavities or old nests, sometimes in communal groups for warmth.

Song & Calls

The Winter Wren's song is a long and melodious cascade, a delightful symphony in the forest, often belying the bird's small size.

Breeding

Males construct several unlined "cock nests," but only one is chosen and lined by the female for breeding. The chosen nest, often hidden in a crevice or bush, is filled with grass, moss, lichens, or leaves. The female lays five to eight white or speckled eggs, and the species may raise a second brood in a season.

Diet and Feeding

Primarily insectivorous, the Winter Wren feeds on insects and spiders, foraging on bark and fallen logs. In winter, it may also consume large pupae and some seeds to sustain itself through the colder months.

Conservation status

The Winter Wren is currently listed as Least Concern by the IUCN, indicating a stable population across its range.
