House Wren - Troglodytes aedonA common hyperactive midget found throughout the South Dakota, a common sound in the summer time is the song of a House Wren, often repeated in rapid succession for long periods of time.  A very aggressive courtship and nesting ritual involves the male building numerous "dummy" nests in any available cavity (nest boxes, trees, buildings, fences, etc).  The female selects one of these, and the male completes that nest.  House Wrens will also aggressively chase other species from potential nesting sites, even going so far to destroy their eggs and kill their young. They have adapted very well to a human presence on the landscape, with nesting and foraging sites often found in suburban yards, parks, and gardens.

Habitat:

Prefers semi-open habitats including residential areas, parks, forest clearings and edges, farmstead groves, and brushy thickets. They shy away from dense vegetation without openings.

Diet:

Mostly small crawling insects and spiders. They also are seen eating snail shells, probably for the calcium needed for egg laying.

Behavior:

Very active forager, moving quickly through primarily lower levels of trees and shrubs, but may also forage at upper levels.  Will also forage on the ground.

Nesting:

May through August in South Dakota. Historically House Wrens nested in tree cavities, or sometimes rock crevices or other natural cavities near open woodland. Nesting now also often occurs in man-made structures, including nest boxes as well as building crevices or even discarded rubbish (cans, boxes) with holes.  The male builds places a multitude of small twigs in several potential nesting cavities, with the female making the final selection for the nesting site. When selected, a cup-shaped depression is built atop the twigs, lined with softer material including fine grasses, hair, moss, or bits of string and debris. The female lays between 4 and 9 eggs and she alone incubates them. The young hatch after 12-15 days, and fledge from the nest about 16 days after hatching. Very aggressive with both other House Wrens and other birds while nesting, they will destroy eggs in nearby nests. Males will even destroy laid eggs of females that have nested with other male House Wrens, mating with the female and beginning their own "family".

Song:

The song of a House Wren is a series of rapid jumbled musical notes, often repeated in rapid succession.  They also have a number of other vocalizations with chattering and harsh scolding notes.

Migration:

Summers through much of the U.S. and southern Canada.  Winters in the southern US, along southern Pacific and Atlantic coastlines, and southward throughout much of Mexico.
