Recovery strategy and management plan for the Red Knot (Calidris canutus) in Canada .: En3-4/260-2017E-PDF
"Red Knot (Calidris canutus) is a medium-sized shorebird with a typical sandpiper profile: long bill and smallish head, long tapered wings giving the body an elongated streamlined profile, and longish legs. In breeding plumage, knots are highly distinctive, with the face, neck, breast and much of the underparts coloured a rufous chestnut red. Three subspecies of Red Knot are known to occur in Canada: Calidris canutus rufa (hereafter rufa) breeds solely in Canada, Calidris canutus islandica (hereafter islandica) breeds in Canada and Greenland, and Calidris canutus roselaari (hereafter roselaari) breeds in Alaska and Russia and occurs in Canada in small numbers during migration. Because of long-term declines; rufa is listed as Endangered, roselaari as Threatened, and islandica as a species of Special Concern on Schedule 1 of SARA. New information has arisen for roselaari since its assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2007 that suggests the subspecies does not breed in Canada (roselaari thought to be breeding in Canada were shown to be rufa) and only a few minor stopover sites have been identified in Canada. The entire global population of rufa, estimated to be 42,000 individuals, is known to breed in Canada. Less than 1% of the current global population of roselaari, estimated to be 17,000 individuals, is estimated to frequent Canada during migration, and approximately 18% of the global population of islandica, estimated to be 450,000 individuals, is known to breed in Canada"--Executive Summary, p. iv.
