Mammals

The numerous fresh water ponds and marshes of the Refuge produce a variety of emergent aquatic vegetation and are usually bordered by riparian areas.  These habitats attract all species of wildlife and are especially critical to the survival of many mammalian species.

  • Beavers

    A mammal with long incisors, webbed feet and long flat tail. Beavers construct dams for homes in lakes and streams by chewing down trees with their large teeth. Usually very shy and active at night, they can be difficult to see.

  • Coyote

    Coyotes have large pointed ears and a fluffy tail. About the size of a large domesticated dog, their tracks can be mistaken for those of domesticated dogs. Coyotes eat small rodents, hares, Canada geese and sometimes larger animals such as newborn fawns.

  • Deer

    Black-tailed deer usually stay within the area where they are born. Males grow branching antlers. Both males and females have dark brown or black flattened tails with white underneath. Like all deer, black-tailed deer browse exclusively on vegetation such as salal, huckleberry, blackberry, bitterbush and snowbrush.

  • River Otter

    Fur-bearing mammal with large canine teeth, long slender body, short legs, four webbed feet and a long tail covered with dense fur. Live in streams, large lakes, rivers and sea coasts. River otters eat a variety of fish, frogs, and occasionally small diving birds and small mammals. They can dive 60 feet below water surface and stay underwater for up to 4 minutes.

  • Mink

    Mammals up to the size of a small house cat, minks have a long slender body, short legs, slender tail and dark brown fur. They can be found around freshwater marshes, streams and lakes. Mink eat muskrats, voles, fish, shorebirds, young ducks and amphibians. Main predators of mink are humans (for their fur), hawks and owls.
