House Wren

The House Wren is a small, energetic songbird with plain grayish-brown plumage overall, finely barred with darker brown on the wings, tail, and flanks. It lacks the bold facial markings of some other wrens, showing only a faint, indistinct pale eyebrow. Its short tail is often held cocked upward, a characteristic wren posture, and its bill is thin and slightly downcurved.

Despite its plain appearance, the House Wren is a familiar and beloved garden bird across much of the Americas, named for its willingness to nest in birdhouses and cavities close to human dwellings, and known for an exuberant, bubbling song delivered with surprising volume and energy.

Key Field Marks

• Plain grayish-brown overall with fine dark barring on wings, tail, and flanks
• Faint or indistinct pale eyebrow stripe (much less bold than in Carolina Wren)
• Thin, slightly downcurved bill
• Short tail frequently held cocked upward

Similar Species

• Carolina Wren: larger, warmer reddish-brown, with a bold, well-defined white eyebrow stripe, unlike the House Wren's plain face.
• Winter Wren: smaller and darker, with a shorter tail and more intricate barring, and a very different, long, warbling song; found more in dense coniferous forest.
• Bewick's Wren: has a longer tail edged with white spots and a clearer white eyebrow stripe, distinguishing it from the plainer House Wren.

Habitat

House Wrens use a wide variety of semi-open habitats with dense shrubby cover, including gardens, woodland edges, thickets, hedgerows, and parks.

Range

They breed across most of the United States and southern Canada, and winter in the southern U.S. and Mexico; closely related forms occur widely through Central and South America.

Migration

Most North American House Wrens are migratory, moving to the southern United States and Mexico for winter, arriving on breeding grounds in spring and departing in fall.

Behavior

House Wrens are active and inquisitive, often investigating cavities and crevices while foraging, and males are known for a somewhat aggressive streak, sometimes puncturing the eggs of other cavity-nesting birds competing for nest sites.

Voice

The song is a rapid, bubbling, cascading series of chattering notes, often described as an exuberant, energetic outburst; calls include a harsh, scolding chatter.

Feeding

They feed almost entirely on insects and spiders, gleaned from foliage, bark, and the ground, making them beneficial predators of garden pests.

Nesting & Breeding

Males build multiple stick-filled "dummy" nests in available cavities within their territory, and the female chooses one to complete with a lining of soft material. They typically lay 5-8 eggs and may raise two broods per season, readily using nest boxes.
