The Pacific Wren was previously considered part of the Winter Wren species but was formally recognised as a separate species in 2010 (Toews and Irwin 2008, Chesser et al. 2010). The species inhabits moist, coniferous forest, west of the eastern Rocky Mountain foothill, breeding throughout coastal and interior British Columbia, southwestern Alberta and rarely in southern Yukon. The Pacific Wren is monitored in Canada by the Breeding Bird Survey, which shows that the population has decreased since 1970, especially since the early 2000s. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Pacific Wrens are common in old-growth forests and rare in young forests, since the former have abundant large trees, snags and logs that provide foraging habitat as well as nest and roost sites (Hejl et al. 2002). There are concerns over the combined effects of forest fragmentation, forest structure simplification and loss of mature old-growth forests (Toews and Irwin 2012).
Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
