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. _Specimens in park collection:_ RNP-101, Longmire Museum, Park Headquarters. 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. THE MEADOW MICE Three species of meadow mice are known to inhabit the park, and of these, two are so similar that the positive field identification of each is difficult in most instances. Only the Cascade meadow mouse, or water vole, shows sufficiently distinctive characteristics to permit easy recognition. Of the two similar species, the Oregon meadow mouse is probably most likely to be encountered.
