Part 7

The big chipmunks are less graceful than their livelier, smaller cousins; they are unsuspicious and easily observed, and are very popular with park visitors because of their obvious lack of timidity. They are quick to adapt themselves to the proximity of humans, and sometimes become nuisances about campsites and dwellings because of their audacious thefts of various foodstuffs.

The capacious cheek pouches are used in collecting seeds, nuts, roots, berries, and the bulbs of various plants, which are stored in underground caches. Although these ground squirrels hibernate from early fall until late spring, forage is meager during the first few weeks after emergence from their long winter nap, and without provision for these lean times, the animals would surely starve. They often appear when the snow is still deep over their burrows, digging several feet upward through this white blanket to emerge on the surface.

The most dreaded enemy is the weasel, but the ground squirrels are preyed upon by coyotes, foxes, and hawks as well, since they are a staple item in the diet of most predators.

DOUGLAS PINE SQUIRREL, CHICKAREE Tamiasciurus douglasii douglasii (Bachman)

A dark grayish brown squirrel about twelve inches in length overall; with prominent ears; moderately slender in form; tail almost as long as the body, somewhat flattened, well clothed with hair but not bushy, more gray than the body. The underparts vary from a pale yellow brown to reddish brown. The sexes are colored alike; the pelage is fairly long, soft, but not silky. The characteristic appearance is one of extreme alertness.

The Douglas squirrel is classified as one of the red squirrels, or chickarees, which are distributed over most of forested North America.

In Mount Rainier National Park these squirrels are common, and are found throughout the area from the park boundaries to forest line, and occasionally even higher.

This vociferous, restless bundle of energy is seen and heard by almost every park visitor, bounding across the highway or trail, or scampering madly up a nearby tree, to peer around the trunk or perch upon limb just out of reach where it scolds and chatters vehemently at all intruders.

Unlike the flying squirrel, the chickaree is abroad throughout the daylight hours, busy, inquisitive, obviously and usually noisily, resentful of interference with what it considers its own affairs. Only in the spring is this squirrel somewhat subdued, probably because of the youngsters tucked away in a nearby nest in some tree hollow. The young do not venture into the world until more than half grown, when they take their places in the regular routine of family activities.

Because the Douglas squirrel does not hibernate, it gathers the cones of most of the coniferous trees, as well as the winged seeds of the vine maple and even mushrooms to furnish food over the lean winter months. The late summer and early fall is a busy time for this industrious fellow. The swish and thump of falling cones is a common sound through the woods when the harvest is in progress. A number of cones are neatly clipped from the tree tops, then the worker descends the tree to gather and store them in a hollow stump, beneath a log or the roots of a tree, or even in a hastily excavated hole in the forest floor. Interrupt this activity by secreting a few of the fallen cones, and the imprecations called down upon your head would scorch the printed page if they could be translated into human speech.

Although preyed upon by winged and four-footed predators alike, the chickaree holds its own very well, probably because this fellow is seldom caught napping, certainly not because of shy and retiring habits, since the “chatterer” is one of the most conspicuous and interesting of our woodland creatures.

CASCADE FLYING SQUIRREL Glaucomys sabrinus fuliginosus (Rhoads)

A medium-sized, arboreal squirrel; dark-brown above, light brown on the under parts, light gray or sometimes light brown on the sides of the face, the sexes colored alike, the young darker than the adults. The eyes are large and dark, the pelage is soft and silky. The flat, furry tail and the fold of loose skin between the fore and hind legs on either side distinguish this animal from any other.

Specimens in park collection: None.

Flying squirrels inhabit a large part of forested North America. The Cascade sub-species is found from southern British Columbia southward along the Cascade Range to the Siskiyou Mountains of Northern California.

Although seldom seen because of its nocturnal habits, the flying squirrel is locally abundant in some sections of the park, particularly at Ohanapecosh Hot Springs.

The most interesting characteristic of this little tree-dweller is its unique habit of gliding from tree to tree through the air. In launching its “flight” the squirrel leaps into space from its perch on a dead snag or tree, extends the fore and hind legs, spreading the loose fold of skin along its sides, and with the flat tail fluttering behind, sails obliquely downward, alighting on the ground or the lower trunk of another tree. This aerial maneuver cannot truly be called flight, but has resulted in the name “flying squirrel.”

Little is known of the life history of this beautiful little animal, because of the difficulty of observation. Old woodpecker holes or natural cavities in trees are favorite nesting places, and the flying squirrel is almost never found away from the nest except at night or when disturbed. It is a shy and retiring creature, preyed upon by owls, martens, weasels, and other small carnivorous animals on the rare occasions when it comes to the ground. Flying squirrels are omnivorous, nuts and other vegetable foods are apparently preferred, although meat is sometimes taken when available.

CASCADE PIKA, CONY Ochotona princeps brunnescens Howell

This small, rodent-like animal is robust, short-legged, with a tail so short that it is not noticeable in field observation. The sexes are colored alike; gray-brown above, whitish below, ears darker, feet light. The pelage is soft and quite dense. In general appearance the pikas closely resemble the rabbits, except for their small size, short legs, and short, rounded ears. The peculiar “bleating” call is unmistakable.

Specimens in park collection: RNP-12, RNP-13, and one mounted specimen; Headquarters Museum, Longmire.

The many sub-species of the pika are widely distributed at the higher elevations throughout the Rocky Mountains and the Coast Ranges. The typical habitat is the rock-slides and talus slopes near forest line.

In the park one may expect to find the pika on any rocky slope from 3,000 (rarely lower) to 8,000 feet. They are infrequently seen in winter, due to the depth of snow over most sites which they inhabit, but during clear, sunny days they occasionally venture out in exposed locations.

The common name “hay-maker” has often been applied to the pika, because it is one of those provident creatures which literally “makes hay” during the summer months, curing and drying a wide variety of grasses and other plants which are stored for winter food. The hay-barn of the pika is in a sheltered crevice or beneath an overhanging boulder in the masses of rock where it makes its home. These hay-piles are much in evidence where pikas are abundant.

The protective coloring of the animal makes it difficult to distinguish among the rocks, and it is commonly heard before it is seen. The sharp, short bleat, almost a chirp or squeak, often repeated at rapid intervals when the pika is alarmed, is distinctive. If the observer remains motionless, and carefully searches nearby with his eyes, he is almost certain to see a tiny “rock-rabbit” scamper quickly and with silent, sure feet across the rocks, to disappear in a crevice or to perch on an exposed boulder. Should the watcher remain quiet, the pika will resume its interrupted activities until again disturbed.

The well-chosen shelter of the pika, deep down beneath the rocks, affords adequate protection from most predators. Only the weasels, and their relatives, the martens, are capable of following these elusive creatures through the talus. Undoubtedly the hawks and eagles may strike suddenly from the air and be successful in capturing a pika less alert than his fellows, but such occasions must be rare.
