Endangered and Threatened Wildlife and Plants; Threatened Species Status for the Rufa Red Knot

We, the U.S. Fish and Wildlife Service (Service), determine threatened species status under the Endangered Species Act of 1973 (Act), as amended, for the rufa red knot (Calidris canutus rufa). The rufa red knot is a migratory shorebird that breeds in the Canadian Arctic, winters in parts of the United States, the Caribbean, and South America, and primarily uses well-known spring and fall stopover areas on the Atlantic coast of the United States, although some follow a midcontinental migratory route. The effect of this regulation will be to add this species to the list of Endangered and Threatened Wildlife.
