The Carolina Wren is a very uncommon species in Canada, with only a peripheral population occurring in southern Ontario and recently Quebec. However, this species is widely distributed and common throughout the eastern United States. In Canada, results from the Breeding Bird Survey suggest a significant increase in the population since 1970. The Carolina Wren is well-adapted to human activities; there are few known threats to its conservation.
A warming climate appears to be responsible for the northward expansion of this species' range (Haggerty and Morton 2014). The Carolina Wren benefits from bird feeding activities and from land uses that create dense edge habitat and thickets (e.g., forest fragmentation and logging; Haggerty and Morton 2014). Severe winters can have devastating effects on local populations, but they often recover within a few years (Haggerty and Morton 2014).
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:
