American Beaver
Castor canadensis
ID Notes 4
The North American Beaver, Castor canadensis, is regularly seen on cameras near ponds, lakes, or streams. The beaver is most often confused with the muskrat or the woodchuck. It is larger than either of these species, and can easily be distinguished if the tail is visible. Beavers have a flat, wide hairless tail that looks like a paddle. Muskrats have a long rat-like tail which is relatively hairless. Woodchucks have furry tails about 6 inches long. If the back feet are visible, this can also aid in identification. Beavers have fully webbed hind feet. Muskrat hind feet are only partially webbed, and woodchuck feet are not webbed at all.
