Black-tailed deer usually stay within the area where they are born. Males grow branching antlers.

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.
