House wren

Description:

Unlike many others, these birds do not have brightly colored feathers.

Measuring 5 inches long with a plump body and a short tail.

The upperparts are unstreaked and grayish brown while the underparts are grayish white.

This bird has no prominent field marks.

If you spend any time at all watching these birds, you'll easily know the extent of its territory.

The male usually has three prominent perches from which he defends his territory of 1/2 - 3/4 acres.

Mating:

In spring, the male wren arrives and begins to establish his territory. You'll know he has arrived when you begin hearing him sing from his perches.

As you watch, you'll notice he begins placing sticks into prospective nest holes. He may build as many as twelve different nesting sites.

He may put more than 400 sticks into one cavity.

After pairing with a mate, the male takes the female to each of the nesting sites he has begun building.

The female selects the one she likes and begins to rebuild by adding soft materials to the nest before laying eggs.

House wrens are cavity nesters and as such, are an ideal candidate for attracting to birdhouses. In fact, these birds seem to prefer man-made nest boxes to natural cavities.

Male House Wrens returning to the North to breed in their first year are more likely to settle close to an established male than farther from it.

Experienced males tend to settle farther apart. Young males may take clues from more experienced males about what areas are good nesting sites.

The House Wren has one of the largest ranges of any songbird in the New World. It breeds from Canada, through the West Indies, through Central America, southward to the southernmost point of South America.

Some of the subspecies living south of the United States have been considered as separate species.

Nesting:

The nesting site can be located anywhere from 4-30 ft. above ground. After choosing and rebuilding the nest, the female will lay 5-6 eggs that are white with brown marks.

Incubation time last 12-15 days and the young will leave the nest in 16-17 days.

For their size, these birds can be very aggressive, often piercing other cavity nesting birds eggs. The male will bring food to the female while she incubates the eggs.

Rarely bothered by general human presence, if you get to close to the nest, you stand a good chance at being scolded.

Some say the scolding sounds a bit like a snake hissing.

Diet:

The House wren diet consists almost entirely of insects, especially when feeding hungry youngsters.
