As usual. Along with seabirds, owing to decisions made by the US government.
The US Government has auctioned leases to drill for oil and gas in the Chukchi Sea off Alaska, putting at risk internationally important concentrations of seabirds, and a number of threatened bird species, including the Critically Endangered Kittlitz’s Murrelet Brachyramphus brevirostri.
Audubon (BirdLife in the USA) says the Chukchi Sea is also home to one-tenth of the world’s remaining Polar Bears Ursus maritimus, and the only population of Bowhead Whales Balaena mysticetus not yet considered by the IUCN to be threatened.
At least 15 species of birds on Audubon Alaska’s WatchList use marine and coastal habitats in the Chukchi Sea. The WatchList identifies declining and vulnerable species and populations of birds.
Bird species at risk include the Vulnerable Steller’s Eider Polysticta stelleri and Near Threatened Ivory Gull Pagophila eburnea. There are two major seabird colonies on the East (Alaskan) coast of the Chukchi Sea, supporting an estimated 850,000 breeding birds between them, mostly Thick-billed Uria lomvia and Common Guillemot (or Murre) U. aalge, and Black-legged Kittiwake Rissa tridactyla. Kittlitz’s Murrelet breeds at both sites.
