Male and female build the nest together on a platform of twigs. The nest cup is made of grass, weeds, moss, and rootlets, lined with hair and feathers. The male may build several dummy nests that remain unlined.
The female incubates 5 to 6 eggs for 12 to 16 days. Both parents feed the young, which leave the nest at about 19 days. On the coast and in the milder Washington lowlands, the Pacific Wren is a permanent resident.
In colder parts of the state, they leave late in the fall for wintering grounds throughout the western United States. They return early in the spring. The Pacific Wren is a common, permanent resident in all forested habitats of western Washington, including large, forested city parks. They are especially common in the dense undergrowth of coastal forests.
In mountainous regions, Pacific Wrens are summer residents, breeding as high as 6, feet on Mount Rainier. In eastern Washington, they are less common but can still be found year round in moist coniferous forests, usually above the Ponderosa pine zone and confined to north-facing slopes with dense trees and water nearby.

Most Bewick's Wrens in Washington are permanent residents. Some birds from west of the Cascades move east into southeastern Washington, eastern Oregon, and western Idaho in the fall, perhaps in a post-breeding dispersal. Bewick's Wren populations are at risk in many parts of the United States, and populations in the eastern part of their range are considered scarce and declining.
Much of the population east of the Mississippi is endangered. Most of this decline is blamed on the expansion of House Wrens, who out-compete Bewick's Wrens for nesting sites. Throughout the western part of their range, including western Washington, Bewick's Wrens are widespread and common. Their population has probably increased since the arrival of European settlers due to the resulting forest fragmentation and increased edge habitat. In eastern Washington, they have been expanding their range eastward and northward since Bewick's Wrens are common year round at lower elevations throughout western Washington.
In southeastern Washington, they are found along major rivers. They can also be found around Spokane. Their population is increasing in eastern Washington, but is still fairly scattered.

The nest's foundation is a large pile of twigs, and the nest itself is a cup built of soft plant fibers, hair, and feathers. The female incubates 6 to 7 eggs for 12 to 15 days. Both parents feed the chicks, which leave the nest after 12 to 18 days.
Some of Washington's birds move up-slope in late summer after the breeding season, and most have left Washington by late September. There are a few accepted records of House Wrens in southeastern Washington in the winter, but they were living in heated stock sheds.
In the spring, males tend to arrive before females. House Wrens currently occupy the broadest latitudinal range of any native songbird in the New World. House Wrens have benefited from the fragmentation of forests across the United States, including Washington. This fragmentation increases the shrubby edge habitat that they prefer. They are fairly tolerant of human activity, which makes them well adapted to our increasingly developed landscape. They also seem to benefit from logging, using slash piles and small snags.
In some areas in the 19th Century, there was a decline of House Wrens, which is blamed on the introduction of the House Sparrow because they compete for nesting cavities. In Washington and North America as a whole, the House Wren population has been on the rise since , increasing an average of 8. This increase may be of concern since House Wrens destroy nests of other species, and compete with other, less common cavity-nesters.
House Wrens are common and widespread from mid-May to the end of August at lower elevations in eastern Washington, outside of the hottest parts of the Columbia Basin.
