The Rock Wren is widespread in arid, rocky habitats in western Canada but is poorly monitored in this country. Results from the Breeding Bird Survey suggest a moderate decrease in the Canadian population since the early 1970s. As a peripheral species, data specific to Canada are scarce and this assessment is therefore considered to be of low reliability. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

General nesting period in Canada

Nesting period starts between mid-May and early June and ends between early August and mid-August, depending on the region. Before or after this period, the probability of an active nest is lower.
 

Conservation and management

Naturally occurring at low densities in areas difficult to reach, containing cliffs and talus slopes, the Rock Wren is not frequently observed (Siddle 2015a). There are few threats to the arid, rocky habitats favoured by the species and few current management concerns (Lowther et al. 2000).

 

Bird conservation region strategies

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:

  • conservation concerns (i.e., species vulnerable due to population size, distribution, population trend, abundance, or threats)
  • stewardship responsibilities (i.e., species that typify the regional avifauna or have a large proportion of their range or population in the sub-region)
  • management concerns (i.e., species that require ongoing management because of their socio-economic importance as game species, or because of their impacts on other species or habitats)
  • other concerns (i.e., species deemed a priority by regional experts for other reasons than those listed above or because they are listed as species at risk or concern at the provincial level)

Select any of the sub-regions below to view the BCR strategy for additional details.
