WASHINGTON (AP) — The Obama administration is moving to protect the red knot, a robin-sized shorebird known for its 10,000-mile (16,092-kilometer) 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 U.S. East Coast are taking a toll on the rosy-breasted bird, which makes refueling stops in Cape Cod and Delaware Bay.
Red knot populations have dropped by about 75 percent in Delaware Bay since the 1980s, a result of shrinking habitat and a drastic decline in the region’s horseshoe crab population. Crab eggs are part of the birds’ diet.
The red knot is already listed as endangered by New Jersey and would join the piping plover as East Coast shorebirds protected under the Endangered Species Act.
Shorebird experts have identified 15 other Atlantic Flyway shorebirds that warrant immediate attention, including the American oyster catcher, lesser yellowlegs, ruddy turnstone and whimbrel.
The once-common coastal species are declining due to threats from climate change, coastal development and hunting, as well as other threats such as oil spills and diminishing food resources, the agency said.
Fish and Wildlife Service Director Dan Ashe called the red knot “an extraordinary bird that each year migrates thousands of miles from the Arctic to the tip of South America and back.” Like many shorebirds, the red knot “is vulnerable to climate and other environmental changes,” Ashe said, noting that steep population declines have occurred in recent years, with much of the decline taking place in the past decade.
More than 100,000 red knots were once common in Delaware Bay, which separates New Jersey from Delaware, but populations have dwindled to about 25,000.
The red knot was one of many species harmed last year by Superstorm Sandy, although officials said the storm played little or no role in the decision to list the bird as threatened.
“I wouldn’t say the listing is particularly tied to Sandy, but (the storm) does underscore or illustrate some of the habitat loss that can be exacerbated by major storms,” said Wendy Walsh, a senior biologist in the New Jersey of the Fish and Wildlife Service.
Altered storm patterns due to climate change “may contribute to the threat” faced by the red knot and other shorebirds, Walsh said.
Under the Endangered Species Act, plants and animals declared “threatened” are considered likely to become endangered in the foreseeable future. “Endangered” means they are in danger of extinction. The law prohibits a person without a permit from killing, shooting, hunting, pursuing, harassing, capturing or engaging in other activities deemed harmful to the endangered or threatened species.
The proposal to list the red knot as threatened likely will be finalized next year.
