Muskrats Enjoying Last Days Above Ice

12-22-14  MUSKRAT IMG_3496Muskrats and beavers are eking out the last few days that they will spend above the ice for perhaps several months. Fortunately for muskrats, they can hold their breath and remain under water for up to 20 minutes, time enough to get from one unfrozen patch of water to another. Once the ice freezes completely, muskrats will use ‘push-ups’ or ‘breathers’ as resting places and breathing holes — masses of vegetation collected from underwater and pushed up through cracks or holes in the ice.

Throughout the year muskrats eat the roots and stems of a number of aquatic plants as well as crayfish, frogs, turtles and other prey, when available. Unlike beavers, muskrats don’t store food for the winter, but forage for vegetation (see green plants on ice). Sometimes muskrats will feed from the winter food supply piles gathered by beavers. They have also been known to use the walls of their own lodge as food.
