Red Knot roselaari type
(Calidris canutus roselaari type)

The roselaari subspecies of Red Knot breeds in northern Alaska and Wrangel Island, and winters along the Pacific coast of Mexico and California, passing through the Pacific coast of Canada on migration. Systematic surveys are lacking, but studies of wintering birds suggest a decrease in the population that is likely reflected in the small number of birds that pass through Canada. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

Conservation and management

Red Knots occurring on the Pacific coast are considered to be C. c. roselaari. Habitat changes at migration sites in Washington, United States, have led to decreased numbers there (Buchanan 2003, Buchanan 2008). Current research on population size and migratory connectivity should lead to improved conservation planning. For information on the legal status of this species under the Species at Risk Act (SARA) and to view available recovery documents, see the SARA Registry.

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.
