WASHINGTON (AP) — The Obama administration is moving to protect the red knot, a robin-sized shorebird known for its 10,000-mile migration from South America to the Arctic.

The Fish and Wildlife Service said Friday it is proposing the bird be listed as threatened under the Endangered Species Act. Officials say rising sea levels and disappearing habitat along the East Coast are taking a toll on the rosy-breasted bird, which makes refueling stops in Cape Cod and Delaware Bay.
