The species are also distinguishable by their calls and songs and some subtle differences in appearance. These species are very similar, but can usually be identified based on range ( see map identification uncertainty may exist where the ranges meet in eastern BC/western Alberta). The Pacific wren was recently classified as a distinct species from the winter wren ( Troglodytes troglodytes), as was the eastern winter wren (now Troglodytes hiemalis). The western subspecies of the house wren is more greyish than the Pacific wren, while Bewick's wren can be differentiated by its bolder white eyebrow stripe. Both are larger, have longer tails, and are paler underneath than the Pacific wren. The house wren ( Troglodytes aedon) and Bewick's wren ( Thryomanes bewickii) are found on BC's south coast. The Pacific wren can appear quite similar to the brown creeper ( Certhia americana), but the birds are quite different in behaviour, as well as appearance: brown creepers are nearly always seen spiralling upwards on the bark of large trees, while Pacific wrens are found low to the ground, foraging near trees and dead wood. Brown creepers have curved bills and white bellies. Click here for a draft range map of this newly identified species.įind more information at the British Columbia Breeding Bird Atlas here. The year-range of the Pacific wren hugs the west coast of North America from Alaska south to California, extending further inland along some parts of this stretch, and transitioning to breeding- or winter-only range in other parts. Despite this strong association with forests, some populations do inhabit more open areas, such as some largely treeless but shrubby islands, as well as riparian corridors, disturbed sites, and in alpine habitats above the treeline. This species is commonly associated with old-growth forests, where logs, snags, and large trees provide abundant quality nesting and foraging habitat. It is generally found in coniferous or mixed forests, only rarely occurring in forests dominated by deciduous trees. This species is a forest bird, generally found in wet, closed forest or forest edge. They are long, complex and cheerful songs, which brighten up the dark forests they frequent. Juvenile plumage is quite similar to adult. The Pacific wren's bill is small and pointed, varying from yellow to blackish. This small bird, which gets to 10 cm long, can also be identified by its disproportionately loud songs. It has a lighter stripe above each eye, as well as on its chin, throat, and above the bill. Its colouring is fairly drab: dark brown overall, with black barring on the wings, and light spots dotting the wing edges. Like other wrens, this small, round bird holds its short and stubby tail in a distinct upward angle, which gives it an easily-recognized silhouette.
