Guide to North American Birds
Conservation status In the west, widespread and common, expanding range northward in some areas. East of the Great Plains it is uncommon, localized, and declining. Formerly a common nesting bird east to the Appalachians, it has completely disappeared from most areas east of the Mississippi River during the last few decades. The reasons for this vanishing act are poorly understood.
Family Wrens
Habitat Thickets, underbrush, gardens. In the west, found in many brushy or wooded habitats at lower elevations, including undergrowth in woods of oak and pine, streamside groves, chaparral, desert washes, suburban areas. In the east (where now scarce), mostly in brushy areas around the edges of woods.
In dry thickets and open woods of the west, this is often a very common bird. Pairs of Bewick's Wrens (pronounced like 'Buick') clamber about actively in the brush, exploring tangles and bark crevices, waving their long tails about, giving harsh scolding notes at any provocation. In the east, this species is far less common, and it has vanished from most of its former range east of the Mississippi River.

Feeding Behavior

Forages very actively by climbing and hopping about on trunks, branches, and twigs of trees, probing into bark crevices or gleaning insects from the surface. Also feeds on the ground, flipping over leaves and probing among leaf litter.


Eggs

5-7, sometimes 4-11. White, with brown and gray blotches often concentrated at larger end. Incubation is probably by female only, about 14 days. Young: Both parents feed nestlings. Young leave the nest about 2 weeks after hatching.


Young

Both parents feed nestlings. Young leave the nest about 2 weeks after hatching.

Diet

Mostly insects. Feeds on a wide variety of insects, including beetles, ants, wasps, true bugs, caterpillars, grasshoppers, and many others. Also eats many spiders, and occasionally some berries or seeds.


Nesting

Male defends nesting territory by singing; songs of eastern birds quite different from those of the west. Adults sometimes puncture eggs of other birds nesting nearby. Nest site is in any kind of cavity, including natural hollows in trees, old woodpecker holes; also in manmade sites, including nest boxes, holes in buildings, mailboxes, tin cans, and many others. Site is usually less than 20' above the ground. Male may build incomplete "dummy" nests; female probably chooses site and completes one nest for raising young. Nest has a foundation of twigs, leaves, bark strips, and trash, topped with a softer cup of moss, leaves, animal hair, feathers. Sometimes adds bits of snakeskin to nest.

Migration

Some are present all year in most parts of breeding range, but many depart from northern areas and higher elevations in winter; may be more migratory in east than in west.

Songs and Calls

Loud, melodious song with the usual bubbly wren-like warble, also reminiscent of a Song Sparrow.

How Climate Change Will Reshape the Range of the Bewick's Wren

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
