Muskrat
(Ondatra zibethicus)
The muskrat is a common resident of wetlands. This rodent likes to feed on cattails, a plant that is abundant in marshes. Muskrats use cattails to build their lodges. A muskrat lodge looks like a small beaver lodge. Canada geese sometimes build their nests on top of muskrat lodges because this height provides the geese with a lookout for predators.
