Part 10

The food preferences and habitats of the snowshoe rabbits are similar. Both species prefer the dense cover of swamps and thickets, which provide excellent protection from hawks and owls above as well as avenues of escape from coyotes, foxes, and other predators on the ground. Every large predator is the enemy of the snowshoe.

Green plants, grasses, and clover make up the bulk of the food in summer. The winter diet consists chiefly of the bark, buds and twigs of various trees and shrubs. Coniferous foliage is often eaten.

WESTERN BUSHY-TAILED WOOD RAT Neotoma cinerea occidentalis Baird

This large, gray-brown rat (head and body nine inches, tail eight inches), can not be mistaken for any other park animal. It closely resembles a several times magnified white-footed mouse, except that the tail is so well-haired as to be almost like that of a squirrel. The ears are conspicuous, the eyes large and lustrous, the feet, underparts, and underside of the tail are dull white.

The wood rats are found over the western United States, northward into western Canada, and in some of the southeastern and mid-western states.

The Mount Rainier species inhabits southern British Columbia, all of Washington and Oregon, northern California and Nevada, and most of Idaho. In the park it is found from park boundaries to forest line, rarely higher, and is not common, although Taylor and Shaw (1919) found it “unusually abundant in the timber along Tahoma Creek,” and recorded one individual at Camp Muir (10,000 feet).

Every woodsman has a fund of “pack rat” stories, nearly all of them emphasizing the thieving propensities of the animal, and every story has a basis, at least, in fact, because the wood rat will usually pick up and carry away anything about the camp that strikes his fancy, if such articles are not beyond his physical powers. At times these treasures may be found cached away in a bulky pile of dead twigs, leaves and other debris in some rock crevice, but the wood rats seem to place little dependence upon these “nests” as a place of refuge, preferring to retreat into a more adequately protected spot in the rock mass itself.

These animals are ordinarily nocturnal in habit, but may occasionally be seen by day. They are not excessively shy, and oftentimes create quite a disturbance with their nightly prowlings when they are found about campsites or dwellings. Their presence is frequently made known by a soft “thump-thump-thump” made at regular intervals of about one second by tapping a hind foot on the ground, rock, or some object.

The wood rat has a distinct musky odor, and a cave, crevice, or cabin in which they have established residence can be recognized at once, even by man’s inferior sense of smell, by the atmosphere.

It is readily apparent from the preceding discussion that the reputation the wood rat has made among woodsmen and campers as a nuisance is not ill-founded. They are interesting and active creatures, however, not nearly so unsavory as the name “rat” implies, and in many instances the entertainment they provide outweighs their less engaging habits.

WASHINGTON WHITE-FOOTED MOUSE, DEER MOUSE Peromyscus maniculatus oreas Bangs

The white-footed mouse is about the size of a house mouse, with the head and body about three and one-half inches in length, the tail about four and one-half inches. The ears and eyes are large; the tail is comparatively long, blackish-brown above, white below. The general coloration over the head and back is a rather dark tawny-brown, intermixed with black hairs, with a preponderance of black toward the base of the tail. The underparts are white, with the lead-gray hair bases showing through; the feet are white. In examining this mouse, the impression is one of an immaculately clean little animal, definitely at variance with the usual conception of mice.

The white-footed mice are distributed over nearly all of North America south of the Arctic Circle.

The Washington species is found in the western part of the state and northward into southern British Columbia. On Mount Rainier it occurs throughout the park to elevations well above forest line, and has been recorded on the summit of the Mountain.

The inquisitive, active, and abundant white-footed mice are attractive and familiar inhabitants of the woods about the Mountain. They are readily adaptable to a variety of conditions, and are quick to invade camps and dwellings in search of shelter and food. They are particularly fond of cereal grains, and will often damage clothing left within their reach, since these materials are evidently highly prized for the nest. Campers will do well to protect food-stuffs and garments from their foraging instincts.

These animals are nocturnal in habit, it is rare to see them abroad by day. They feed upon a wide variety of plant seeds and vegetable material, and are preyed upon by all of the four-footed carnivores, as well as the owls.

RAINIER POCKET GOPHER Thomomys talpoides shawi Taylor

The sturdily built pocket gopher, with its long, sharp, fore claws, tiny eyes and ears, external cheek pouches, robust body, and short legs, can hardly be confused with any of the other rodents. The head and body are about six inches in length, the thinly haired, whitish tail about two and one-half inches. The color is light brown above, with the lead-colored hair bases showing through in places; paler brown on the sides; gray-white below, with white on the throat and a small, irregular white patch on the nose.

The pocket gophers are widely distributed over western North America, and are abundant in many regions.

In Mount Rainier National Park the local species is found on the east side of the park in the Hudsonian Zone above 4,500 feet, usually on the grassy hillsides and in the open meadows.

These animals are burrowers in the true sense of the word, rarely venturing above ground, but constructing elaborate systems of connecting tunnels a few inches beneath the surface. Because of this subterranean habit they are seldom seen, although the evidences of their presence may be conspicuous. Mounds of freshly turned earth scattered about over a meadow indicate that active excavations by pocket gophers are in progress.

The fore claws are well adapted for the purpose of digging, and as the burrow progresses, the earth is disposed of by thrusting it out through a surface opening. Careful observation may be rewarded by a glimpse of the head, shoulders and forelegs as the gopher accomplishes this disposal, thus forming the mound of earth, which eventually closes the emergence-hole. When not in use, these openings are closed by earthen plugs.

Pocket gophers feed almost exclusively upon the roots and bulbs exposed by their burrowing activities, although at rare intervals they may move a short distance from the burrow to gather surface food.

Earth excavated during the winter months is firmly packed in tunnels which the gopher makes on the surface of the ground beneath the snow. These winding ridges of earth are revealed by the melting snow as further evidences of pocket gopher activity.
