Dense tangles and thickets in coniferous and mixed forests.
Breeds from Aleutian Islands and Alaska south along the Pacific coast of North America to central California, inland to Alberta, Utah, Idaho and Arizona. Many populations are year-round residents throughout much of the breeding range. Migratory birds winter in inland Oregon and Washington, and on the southern California coast. Care is needed in Alberta and throughout the Rocky Mountain region due to ranges close to those of the very similar Pacific Wren. Vagrants of either species are possible in the Rockies.
This wren moves like a mouse, creeping through the low, dense tangle of branches covering the forest floor. Its nest is among the hardest to find; even when an observer has narrowed the search to a few square feet, he must sometimes give up, so cleverly is the nest concealed. The Pacific Wren's song, when recorded and played back at half- or quarter-speed, reveals a remarkable blend of halftones and overtones all sung at the same time. The Pacific Wren is a newly recognized species, arising from the split of the Winter Wren into three species, two of which (Winter Wren and Pacific Wren) occur in our range. The third species (Eurasian Wren) is a common bird with a wide range in Europe and Asia, but would be an extremely rare vagrant anywhere in North America.
