Cactus Wrens are easier to recognize with their speckled undersides, large bold eyebrow stripe, and large size. They are recorded in 1% of both summer and winter checklists for the state. Pacific Wrens can be spotted in California all year and appear in 2% of summer checklists and 1% of winter checklists for the state. Marsh Wrens are brown with black and white streaks on their back.
Breeding and Feeding
It appears that this isolated population has disappeared. Small patches of cacti remain in this area, but recolonization seems unlikely, because Cactus Wrens require large, intact stands of cacti. Plumage color varies regionally from rusty in more humid regions to gray in desert regions. Birds from San Francisco Bay south to Monterey, California, have less rusty coloring than birds farther north. Canyon Wrens are at home in places without water because these birds don’t need to drink! Even when they are near a water source, they are not seen drinking.
Relative Size
They may build a completely new nest in the same spot each season, or they may simply move on to a new nesting spot. Some birds will reuse their existing nests year after year, while others build a new nest every season. Wren eggs are no different from other types of birds in this regard.
What wrens have you seen before in California?
A "brown-throated" subspecies of the House Wren occurs in mountains of extreme southeastern Arizona. It has a distinct buffy eyebrow and cinnamon-buff throat and chest. House Wrens occur all the way through the Americas to southern Argentina. Individuals in the Caribbean and South America tend to be warmer colored and have somewhat different voices. Dark barring on the wings and tail contrast with the more uniform brown plumage elsewhere. Forages fairly low in tree branches and shrubs, eating mainly insects and spiders.

Other weird spots for nests include boots, cans, or boxes. Even though they almost never visit bird feeders, they are often seen zipping through backyards while hunting insects. A great way to draw these wrens to your yard is to create brush piles, which offer cover for them and places for insects to gather. Bewick’s Wrens are the most frequently spotted wrens in California, and they do not migrate.

House Wrens aren’t too particular about where they build their nests. They prefer cavities in trees for ultimate protection from predators but love man-made nesting boxes even better than naturally occurring cavities. Let’s dive into what the Wren mating season looks like and how they raise their young as the season progresses.
After nesting season, most U.S. and Canadian House Wren populations migrate to the southern United States and Mexico for the winter. The female will lay one egg daily and often leaves the nest to find food before laying another egg the following morning. If you find a wren nest unoccupied with a few eggs, it doesn’t mean that it’s abandoned. It simply means that the female isn’t done laying her brood. At the start of the breeding season, the male House wren seeks out eligible nesting cavities and begins preparing them for nesting. First, he lines the nests with sticks, sometimes comprehensively with hundreds of sticks, other times with just a handful of sticks.

Where do House Wrens nest in the winter?
Measuring 5 inches long with a plump body and ashort tail. Even if no birdhouse is offered, these birds are likely to find somewhere or something to nest in around your home. House wrens rarely abandon their nests and will only risk doing so if the nest is under indefensible threat or otherwise fails, e.g., due to insect infestation or flooding. Parents make a combined 20 to 30 trips to and from the nest each hour. The female House Wren might make 200 to 300 trips back and forth from the nest in this time in a process that can take as long as 14 days.
After pairing, the female selects the nest site and starts filling the nest with more twigs. The upper parts are unstreaked and grayish brown, the underparts are grayish-white. Notice the faint or missing eye stripe that iscommon in other wrens. Unlike many other birds, House Wrens do not have brightly colored feathers or markings.
Although many birds fiercely defend their territories during the breeding season, the House Wren takes this behavior to an extreme. Males will also stuff cavities with twigs to keep other birds from nesting there. House Wrens raise two broods per season, but sometimes they have been spotted raising to three on occasion. The clutch size varies from 3 to 10 eggs, with an average of between 5-6 eggs. While House Wrens aren’t too picky on their nesting locations, there are a few key things to keep in mind.
Nesting boxes suitable for House wrens can have a base as small as 4 x 5in. Artificial nesting sites range from cavities in rotting or decaying structures to novel choices like coat pockets, tin cans, ornaments, abandoned vehicles, and machinery. In addition, nests have been found in boots, shoes, and a multitude of other small artificial cavities. Egg-laying begins soon after the female finishes lining the nest cup. Once the female starts laying eggs, she lays one egg every day in the early morning hours. The breeding grounds encompass roughly the upper two-thirds of North America, which is not far from the wintering grounds in Southern U.S. and Mexico.
Interestingly, House Wrens are one of the only birds that will use a nest box hanging freely and not permanently attached to a tree or post. House wrens usually lay anywhere from 5 to 8 eggs per brood, and sometimes more. By maintaining a clean nest box, you increase the chances of attracting wrens and other cavity-nesting birds to use the birdhouse for their next brood.
Potential female mates arrive in the breeding grounds a few days later than the males and inspect nesting sites and territories. If she approves of a nest site and territory, she stays with the male and begins to construct the rest of the nest over the base of sticks built by the male. Look for a rather large wren with a long tail and long bill, but short rounded wings. They are beautiful birds with their distinctive bright white eyebrow, brown spotted belly, and a brown and white streaked back. Even though Marsh Wrens are tiny, they are incredibly fierce, aggressive, and active.
Their underside is grayish brown, and they have the distinctive upright tail of the wren. Attract House Wrens to your backyard by leaving piles of brush or putting up a nest box. House Wrens eat insects and spiders, such as beetles, caterpillars, and flies.
After the male finds a mate, the female takes over building duties and finishes the nest. Nests typically feature hundreds of small sticks (around 300 to 500 or so in some studies). When House wrens breed further north, they begin selecting nesting sites as soon as they return from migration in late winter or early spring.
