Red Knot (Calidris canutus) migration on the Pacific coast of the Americas

The Pacific Flyway population of Red Knots (Calidris cantus roselaari) uses key stopover sites in coastal Washington during spring migration. In contrast to C. c. rufa, which occurs on the Atlantic coast, almost nothing is known about the ecology and status of C. c. roselaari.  C. c. roselaari was proposed for listing, but the USFWS lacked sufficient information upon which to adequately inform a listing decision.  Beginning in 2006, we investigated aspects of Red Knot migration in coastal Washington, and provide a summary of that information here.
