Habits and Nature of the Muskrat.
The rodent quadruped muskrat, also known by the Indian name "Musquash" is a small amphibious animal of North America, being found as far north as Labrador and Alaska, and ranging south as far as the states of New Mexico and Arizona. There is only one species of the muskrat, but naturalists recognize several varieties or subdivisions, the differentia lying mainly in the color of the fur, firmness of the skin or pelt, and the physical dimensions of the animal. For example, the muskrats of the Atlantic coast states are comparatively large and of dark color; while those of the Northwest prairie region are smaller, thin and papery in pelt (except those living in clear or cold water streams) and of paler color. These variations are no doubt due to climatic and local conditions under which the animal lives.
Generally speaking, it may be said that the muskrat is a nocturnal animal, but where they are plentiful they are frequently observed prowling or swimming about during the day. It is found at home in rivers, lakes and ponds. When inhabiting the former it lives in burrows dug in the banks; the entrance to these are usually several feet under water. They are found to be most numerous in swamps which are heavily bordered with grasses and thickly strewn with scattering growths of aquatic vegetation. The roots of these plants compose the principal diet of the animal, while the tops furnish the material for the construction of their homes. The marsh 'rat differs in its mode of living from that of its brother the "river 'rat," by its habit of constructing dome-like houses. This change in abode is due to the natural environment in which it lives. In many large swamps scores of these queer little dwellings can be seen towering above the water. They average about three feet in height, and are composed of the roots and stems of grasses, reeds, wild rice and flags. The entrances are located under water. From four to eight 'rats are generally found in one house.
The muskrat is a herbivorous animal. Its food consists of the roots of flags, water lilies, etc. It is also very fond of sweet apples and vegetables, and will often raid a garden when located near its haunts. It is also partial to grain, especially corn.
Although the muskrat is herbaceous by nature, it is known to eat the flesh of clams. These it carries upon shore, deposits them in a pile in some secluded retreat and leaves them to die, whereupon they are easily opened and devoured with much avidity. The general assumption is that the animal eats these clams only when other food is scarce. This, however, is entirely in discord with the observations of the author, who has on several occasions discovered 'rats feeding on clams when their favorite food was plentiful. Therefore, it is only logical to presume, that it is not the lack of food that attracts the 'rat's attention to the lowly clam, but it is the abundance of the mussel in itself.
Muskrats are our most prolific fur bearers, producing from two to three litters in a season, the first making its appearance in the latter part of April or early May. The period of gestation requires about forty-five days. The young of the early spring litters will frequently rear one family during the same season. It is this progeny of these young females that accounts for the numerous kitts (immature muskrats) taken during the early part of the trapping season.
Considering the wonderful procreative powers of this little animal, it appears that they would become as numerous as the proverbial "hair on a dog's back," but they have many enemies, of which man with his traps and firearms is the most deadly, with perhaps the mink a close second. Many a time has the writer in his ramblings come onto a 'rat house, which had a small round boring at the water-line, just large enough to allow the long, slender body of a mink to pass through. To the casual observer this would appear to be merely a hole, but to the trained eye of the trapper it reveals a tale of woe. He knows that here, during the long, tranquil hours of the night, another family of muskrats was sacrificed to satisfy the flagrant craving of this bloodthirsty member of the weasel tribe. When a mink enters a house or burrow, in the aforesaid manner, the inhabitants flee by way of the diving hole. If everything remains quiet, they will return, one by one, to their home in a very few minutes. The crafty mink, knowing the nature of the muskrat, crouches near the diving hole, remaining very quiet, and bounces upon the poor, unsuspecting victims as they emerge.
Occasionally a trapper may come upon the remains of a muskrat and, following an investigation, cannot detect any clues as to the identity of the assailant. When there are no telltale tracks about, then it is safe to assume that the marauder was an owl or some other bird of prey.
The otter, fox and coyote can also be listed as enemies of the muskrat, as they too make an occasional capture.
