Yukon Delta National Wildlife Refuge

in the Yukon Delta National Wildlife Refuge The refuge's coastal region bordering the Bering Sea is a rich, productive wildlife habitat supporting one of the largest concentrations of water fowl in the world. More than one million ducks and half a million geese use the area for breeding purposes each year, including eider, harlequin duck and emperor goose. There are also very large seasonal concentrations of northern pintail, loon, grebe, tundra swan and cranes. This national wildlife refuge is home to mammalian species such as muskrat, snowshoe hare, brown bear, muskoxen, Dall sheep, moose, black bear, coyote, Canadian lynx, porcupine, beaver, red and Arctic fox, river otter, marten, wolverine, mink, polar bear, and wolf packs. Often trailed by the wolves, some of the 150,000+ Mulchatna caribou herd migrate onto the eastern tundra areas during the fall and winter. Walrus, seals, sea otter and porpoise can be found in the waters as well as Orca, beluga, gray, humpback, bowhead and minke whale. ==See also==
