Although muskrats are primarily nocturnal, you occasionally see them in the daytime, especially in the spring and fall. They often reside in ponds or marshes, where they live in the pond bank or build their own house out of mud, cattails and other available plant material. Muskrats are herbivores, favoring cattail roots, arrowhead, bur reed, pickerelweed and other aquatic vegetation. The pictured muskrat is not feeding, however — more often than not muskrats eat their food where they find it, especially during the warmer months. It is doing its share of parental care — this is the time of year when the first of several litters of muskrats are born. While the mother nurses her four or so young, the father spends time gathering bedding material for his offspring. The muskrat in this photograph spent a morning cutting and gathering several mouthfuls of grasses growing by the side of the pond. When he couldn’t fit one more blade of grass in his mouth he would scurry down the bank and disappear into a burrow which most likely led to a chamber where his young are being raised. Like their beaver cousins, muskrats tend to keep a tidy house and forage for fresh bedding for their young with some regularity.
