Consider putting up a nest box to attract a breeding pair. Attach a guard to keep predators from raiding eggs and young. Find out more about nest boxes on All About Birdhouses, where you'll find plans for building a nest box of the appropriate size for House Wren. House wrens in North America typically attempt two broods every breeding season. The clutch size for the first brood early in the nesting season ranges between 4 to 7 eggs. Breeding house wrens typically reuse the same nest when they attempt a second brood.
Do male or female House Wrens build the nest?
Many wrens usually raise two broods, which takes them all the way through to July and August. Wrens have a long breeding season compared to many birds. Nests are chosen in a huge variety of small cavities, but House wrens prefer pre-formed cavities in trees. Bewick’s Wren populations have declined through the years, and one of the main reasons is increased numbers of House Wrens. Unfortunately, when competition arises, it’s the House Wren that typically wins, as they are known to destroy nests and eggs. Canyon Wrens are stocky brown birds with white throats and lighter barred tails.

All About House Wrens (Troglodytes aedon) (HOWR)
They have a short tail, thin bill, and dark barring on their wings and tail. There are numerous species and subspecies of wren, and they build their nests in different ways and places. The house wren, for example, builds its nest in hollows of houses, barns, and other buildings, including nesting boxes you may set up in your yard. This species is the most common wren in North America, present throughout most of the continent during summer.
House wrens are cavity nesters and will nest in virtually any small cavity ranging from a coat pocket to an old woodpecker nest. The cavity only needs to be around 10cm x 10cm x 10cm in size - these are exceptionally small birds. House wrens can also use crevices at buildings and are creative in finding structures for a nesting site.
Feeding Behavior
There are 11 species of wrens spotted in North America, and of these, nine have been found in California. Eight of those in California are classed as regularly occurring, and one is accidental. They are year-round residents in South America, the southern half of Central America, and in some parts of northern Central America.
Most wren eggs come in various shades of brown with darker dots or splotches. Some are white or beige with splotches, some are a light sky blue with splotches, while still others are pure white with only a scattered number of brown dots. Wrens typically have two broods per season, with the nesting season usually occurring between March and July depending on region.
Wrens: Mating Habits, Nesting & Eggs
Some of you may wish to purchase a house instead of building one yourself. Here is our current recommended style of Wren birdhouse. The plan below is a very common example of a wren house, but if you'll notice, the plan calls for a 1 by 6 by 4 inches when they mean a 1 by 6 by 4 feet, not 4 inches. The baby wrens do not return to the nest once they leave. When it gets close for the young to leave the nest, you will notice the adults are around less frequently. Fewer feedings will encourage the young to leave the nest.
Studies in Wyoming, New York, and Ohio indicate first eggs are laid in mid-May, whereas in southern California, some eggs appear in April in warm lowland areas. First eggs are laid as early April in warmer parts of the US and Mexico or as late as May at northern latitudes. House wren nests are small, measuring as little as 10 x 10 x 10cm, with an internal volume of 1000cm2. Larger nests double that size have been reported, but some are smaller, measuring just 800cm2 or so.
They are recorded in 18% of summer checklists and 16% of winter checklists submitted by bird watchers for the state. Wrens build their nests in a number of spots and at a number of heights–anywhere from 5 ft to 30 feet off the ground. They tend to build their nests near good food and water sources, with lots of insects to eat, as well as berry plants and grasses. Why House Wrens go after the eggs and young of other species (especially those who don’t nest in cavities) is difficult to explain. It might reduce competition for food, suggest some researchers. But perhaps there’s simply no downside to destroying any and all unrelated eggs—for the wrens, anyway.
Plus, learn the differences between a house wren and a Carolina wren, and between wrens and sparrows. House Wren’s song is a vibrant and energetic chattering made up of many churrs and chatters. Both sexes sing, although females sing to answer their mates and include high-pitched squeals. Mated males sing a whispering song that is only sung during copulation. House Wrens call with different rattles, churrs, chatters, and scolds.
The pale eyebrow that is characteristic of so many wren species is much fainter in House Wrens. If you are watching a family of wrens that moved into one of your nesting boxes, you can expect to start hearing babies chirping in about 12 to 15 days. Wren eggs can be various colors depending on the type of wren that laid them. The house wren, as noted above, may be white with reddish brown splotches or more brownish with darker brown splotches. Nests in tree cavities and birdhouses, where it is a strong competitor for nest sites and may evict larger birds to claim the spot for its own. They love spiders, crickets, mealworms, and even catch flying insects.
