Mammals of Mount Rainier National Park

Part 2

Chapter 23,878 wordsPublic domain

There are no mammals which may be considered as characteristic exclusively of the Canadian Zone, since those occupying this zone also range into the Hudsonian.

_Hudsonian Zone:_ At an elevation of from 4,500 to 5,000 feet the character of the forest cover begins to change. The trees are smaller, and the alpine fir and mountain hemlock become dominant tree species. Ascending to higher levels the forest becomes broken, with the number and extent of grassy parks and subalpine meadows increasing until finally all tree growth vanishes at an elevation of about 6,500 feet. This is the zone of beautiful summer wildflower gardens, a region of extensive panoramas and rugged mountain scenes. The avalanche lily, glacier lily, the heathers, paintbrushes, and the mountain phlox are common, as well as the white-barked pine.

Snow blankets these highlands throughout most of the year, and the larger mammals are usually at the lower elevations during the winter months. Many of the permanent wildlife inhabitants are those which hibernate or are active beneath the snow, as the Hollister chipmunk, marmot, pika, Rainier meadow mouse, and Rainier pocket gopher.

_Arctic-alpine Zone:_ Above the forest line all plant life diminishes rapidly in extent. This is a region of barren, rocky soils; perpetual snow fields; and glacial ice; a bleak and forbidding expanse of awe-inspiring grandeur where the storm king yields supremacy for only a few brief weeks in mid-summer.

Characteristic plants, found in the lower portions of this zone, include the Lyall’s lupine, Tolmie’s saxifrage, mountain buckwheat, and golden aster.

Only one mammal, the mountain goat, may be considered as characteristic of this zone.

THE MAMMALS

COLUMBIAN BLACK-TAILED DEER, BLACK-TAILED DEER _Odocoileus hemionus columbianus_ (Richardson)

The Columbian black-tailed deer is a typical member of the deer family, about the size of its eastern relative, the white-tailed deer. The antlers of the males are forked, rather than having the tines rise from a single main beam as do those of the white-tail. The upper surface of the tail is conspicuously dark brown or black over its entire length. The color of the pelage varies with the season, but is the same in both sexes. In summer the back and flanks are reddish to reddish yellow; in winter gray, intermixed with black, with a dark line along the back, black on the top of the head, and conspicuous white on the chin and upper throat. The underparts are sooty, with white on the inner sides of the legs. The young, at birth, are a dark, rich brown, profusely spotted with creamy yellow. The dark coloration very shortly fades to a lighter brown, or reddish, similar to the summer coat of the adult, and the spots disappear in the early fall when the change to winter pelage begins.

_Specimens in park collection:_ RNP-14 and RNP-113; Longmire Museum, Park Headquarters.

The range of the Columbian black-tailed deer is the Pacific Northwest from northern California to British Columbia and from the Sierra Nevada and Cascade Mountains to the Pacific Coast.

It is the most common large animal in the park, distributed in summer throughout the forested areas and occasionally wandering above tree line, the males generally ranging higher than the females and young, preferring the sub-alpine parks and meadows. Deer in general exhibit a preference for burned-over brush lands and other less densely forested areas.

In winter they are found at lower elevations, usually below snow line, generally outside park boundaries, although common along the Nisqually River from Longmire Meadows downstream, along lower Tahoma Creek, and in the vicinity of the Ohanapecosh Hot Springs and lower Carbon River.

Nearly all visitors to Mount Rainier National Park soon become familiar with this graceful animal so commonly seen along the trails and roadsides. Indeed, it is a rare occasion when one or more deer are not seen in a short drive or hike in any section of the park. It is only with the arrival of the snows that they are less frequently observed, and even during the winter months they are quite abundant at the lower elevations.

The seasonal migration is a noteworthy characteristic. With the coming of spring, deer move upward from the lowlands, closely following the retreating snow. The young are born in late May or June, usually after the does have reached their summer range, although they may move higher to find relief from flies. There is practically no banding together of the deer at this time. Each mother and her offspring, usually twins, sometimes one and rarely three, comprise a family group, and tend to keep to themselves. The fawns are hidden at birth, and remain in some secluded spot until they are several days old. The mother visits them at intervals during the day so that they may be fed, and stays near their place of concealment. Almost every season “abandoned” fawns are discovered and brought in to one or another of the park’s ranger stations by well-meaning but ill-informed park visitors. In exceptionally rare instances the mother may have been killed by some predator or a passing automobile, but under no known circumstances has a fawn ever been deliberately abandoned. _Fawns, if found, should be left unmolested._

At the time of the spring migration to the uplands, the older bucks habitually move to higher levels than do the young bucks and does. They prefer the subalpine parks and meadows, and often range in pairs or in groups of from three to five or six individuals.

The first heavy snow starts the deer on their annual trek to the lowlands, and the journey is ordinarily a consistent one, once begun it is completed over a period of from several hours to a day or two, depending upon the distance to be covered. Study has revealed that deer follow regularly established routes during migration, returning year after year to the same general winter and summer ranges. Well-worn game trails along prominent ridges and watercourses are testimony to this concentrated movement, the intersecting minor paths are but tributaries to the major current of travel.

It is prior to the fall migration that the deer herds assemble, the does, fawns, and yearling bucks banding together, the older bucks breaking away from their summer associations and joining the does for the mating season, which occurs in November and December.

Vicious battles are frequent at this season. Determined to assert supremacy, the bucks are merciless antagonists, and at times the struggle is fatal to the loser. In rare instances both may perish, with antlers so tightly locked that escape for either is impossible, exhaustion and starvation the inevitable result. At the conclusion of the mating season the two sexes go their separate ways again, the bucks often assuming again the easy companionship of the summer months.

The abundance or lack of forage is an important factor, perhaps the most important, in determining local abundance of deer. Densely forested sections are not capable of supporting large deer populations because of the lack of sufficient brush, shrubbery, and succulent plants which make up the bulk of the deer’s diet. Primarily a browser, only in spring does this animal show a preference for grass, and then only for a short period.

Deer have many natural enemies. It is fortunate that nature has provided for an abundant reproduction in this species. Snow is perhaps most serious of all, since a heavy snowfall may cover the food supply, and certainly hampers the movement of the animals when they must escape predatory coyotes or cougars. Late spring snows, in particular, come at a critical time. At best forage diminishes steadily during the winter months, and when this period is followed by even a short space when food is unavailable, starvation and death strikes the weaker and aged animals.

Of the predatory animals, the coyote and cougar are most effective. The fox, wildcat, and bear undoubtedly take an occasional fawn, but cannot be considered dangerous to an adult deer. In view of the powers of rapid reproduction shown by deer, it is well that they have numerous natural enemies; otherwise wholesale destruction of brush lands and forest reproduction would occur as the animals reached a peak of overpopulation, followed by mass starvation. This frequently happens in many parts of the West where the natural enemies of the deer have been exterminated. Predators follow, in most instances, the line of least resistance. As a consequence, it is the weaker, the diseased, or the otherwise unfit animals that tend to be struck down first, and so the fittest survive.

A reasonable balance seems to have been attained in the numbers of deer in the park. For the past several years there has been no apparent change, an estimated 600 range within park boundaries during the summer months.

ROCKY MOUNTAIN MULE DEER, MULE DEER _Odocoileus hemionus hemionus_ (Rafinesque)

The mule deer is similar to the preceding subspecies in general character. Perhaps the most noticeable field difference is the tail, which in the mule deer is narrow and black-tipped, above _and below_, rather than wider and dark brown or black over the entire upper surface and entirely white below as in the black-tailed. The large ears, from which this species derives its common name, are distinctive, the black-tailed deer is the smaller and darker of the two subspecies.

_Specimens in park collection:_ None.

The mule deer ranges over most of the Rocky Mountain region and the western United States, from the Dakotas, Nebraska, Kansas and Oklahoma westward to eastern British Columbia, Washington, Oregon and California.

The range of this species in the park is at present restricted to the extreme northeastern section, where it is observed on rare occasions during the summer months.

The mule deer is very similar to the black-tailed deer in habits as well as in appearance. Seasonal migrations, food preferences, natural enemies, and other characteristics are much alike in both species, although the mule deer habitually favors a more sparsely timbered, less rugged terrain.

The typical habitat is an open forest, with many parks, meadows, and brush-covered hillsides. As a general rule the mule deer prefers the Ponderosa pine and sagebrush region, and avoids densely wooded areas. The occasional records of this species in the park are of those rare stragglers which drift in from east of the Cascade crest.

Taylor and Shaw (_Mammals and Birds of Mount Rainier National Park_, 1927) state that mule deer “May occur in small numbers in the White River region, on the east side of the park.” Although their parties did not observe mule deer while in the field in 1919, they believed that observations made by others familiar with the region were reliable.

A report submitted by the chief ranger of the park in 1932 states: “While mule deer are rarely seen they do range along the east side.” It was not until 1941, however, that this species was included in the park’s annual wildlife census, when it was listed as, “Uncommon, only a few have been seen. Tipsoo Lake, Deadwood Lake, and Yakima Park.”

The 1948 wildlife census estimates 10 to 20 mule deer observed occasionally on the east side during the summer months in previous years. While no reports were recorded in 1948, it is believed that the status of the species is unchanged.

AMERICAN ELK, WAPITI _Cervus canadensis nelsoni_ Bailey

The elk is the largest animal found in the park, and the largest member of the deer family found in North America, except the moose. The adult males have tremendous, wide-branching antlers, which are shed annually. The sexes are slightly different in coloration, with females lighter than the males. The head and neck are dark brown, flanks and back a tawny to brownish gray, large yellowish rump patch, legs dark brown. The young are light brown, spotted with white. An adult male in good condition will weigh from 800 to 1,000 pounds; females are somewhat smaller.

_Specimens in park collection:_ None.

Elk are found in western North America, mostly in the Rocky Mountain area and the far west. They formerly ranged over most of the United States and southern Canada.

During summer elk occur in the park along the eastern boundary, north and west to the Deadwood Lakes and Goat Island Mountain, up the Cowlitz River and Stevens drainages to The Bench on the north side of the Tatoosh Range. They are reported very rarely from the northern and western slopes of the Mountain. In winter a few elk range along the Ohanapecosh drainage in the southeastern part of the park.

The early settlers of this country gave the name “elk” to this magnificent member of the deer family. This is an unfortunate designation, since the animal in no way resembles the Old World elk, which is actually a moose. However, elk it has been since early American history, and elk it is likely to remain, although the Indian name “wapiti” seems preferable and more appropriate.

The history of the elk in Mount Rainier National Park is an interesting study. There can be little doubt that the Roosevelt or Olympic elk, _Cervus canadensis roosevelti_, formerly ranged over much of the Cascade Range in the State of Washington, and so must be considered the native species of Mount Rainier, although no longer found in this region.

An attempt was made to reestablish the Roosevelt elk in the park in June, 1934, when two young animals, obtained from the Washington State Department of Game, were liberated at Longmire Springs. Two more were released in October, 1934; all had been captured on the Olympic Peninsula, and the four were to form a nucleus for the park herd.

However, to the keen disappointment of park officials, the transplanted elk were unfavorably affected by their proximity to civilization, as is often the case with wild creatures. So unafraid did they become that soon they were regarded as a nuisance, a dangerous nuisance because of their size, pugnacity, and their total lack of timidity, and recapture and deportation to a nearby zoo was the final step in this attempted repatriation.

The elk now ranging into the park have been introduced on lands outside park boundaries by the Washington State Department of Game and the Pierce County Game Commission. These animals belong to the species called American elk, _Cervus canadensis nelsoni_, and were imported from the Yellowstone region. They do not differ greatly from the native species, though somewhat smaller and lighter in general coloration.

The seasonal migration of elk is well defined. Early in spring, with the retreat of the snow from the uplands, they move to higher pastures, where they remain until driven down by the approach of winter. During recent years a gradual increase in numbers and an extension of range within the park has been observed. The wildlife census for 1948 estimated the summer herd to number some 40 to 50 individuals, with several animals wintering along the Ohanapecosh drainage in the southeastern section of the park.

Bull elk are the most polygamous of all deer. During the mating season, which occurs late in the fall, a single bull will gather together a “harem” of from three or four to as many as two dozen cows with the current year’s calves, and defiantly assert his mastery over the group, driving away younger bulls of lesser strength. Should another bull challenge his dominance, the ensuing battle is rarely fatal, although it may result in a new master. It is not unusual to see the loser, reduced to the status of a “bachelor bull,” ranging alone.

The “bugling” of the bulls, a shrill, high-pitched invitation to combat, is a thrilling call, an unusual record of the music of nature.

The young are born in late May or June, usually one to a mother, sometimes two, and rarely three. Like all deer, they are spotted, somewhat lighter in color than the fawns of the black-tailed deer. The spots are retained until replaced by the winter coat.

CASCADE MOUNTAIN GOAT, WHITE GOAT, MOUNTAIN GOAT _Oreamnos americanus americanus_ (Blainville)

The goat is completely unlike any other park animal, and is easily identified by its resemblance to a large white or yellowish-white domestic goat. Both sexes have short, black, sharp-pointed horns, and are otherwise alike, except that the males are generally somewhat larger, and have a distinct beard.

_Specimens in park collection:_ None.

The Cascade mountain goat is found in the Cascade Mountains of Washington. Records indicate that it probably ranged into the Oregon Cascades some decades ago, but there are no recent authentic reports from that area. Sub-species similar to the Cascades goat are found in the northern Rocky Mountains, northward through Canada and into Alaska, as well as on the Olympic Peninsula.

In the park in summer this denizen of the rocky crags is rather frequently seen in the high country on all slopes of the Mountain. The principal bands may be found in the region of Van Trump Park, Cowlitz Rocks, Cowlitz Chimneys, Steamboat Prow, Burroughs Mountain, the Colonnade, the Puyallup Cleaver, and Emerald Ridge, where they normally range at elevations of from 6,000 to 10,000 feet.

In winter it is not uncommon to observe small bands on Cougar Rock, the southern slopes of Tum-Tum Peak, Mount Wow, lower Emerald Ridge, Mother Mountain, and the western slope of Chenuis Mountain.

Here we have another example of an animal that has been misnamed. Although it is called a mountain goat it is not a true goat, but is more of a rock antelope. Its nearest living relatives are the Alpine chamois of south central Europe and the Himalayan serow of Asia. At one time near relatives of our present goats were spread over much of the western part of North America and fossils have been found in caves in lower Grand Canyon and as far south as Nuevo Leon, Mexico. While it is not known what happened to cause their extinction over much of their original range, it appears likely that early man had an important part in it. It is known that the Indians of the Mount Rainier country hunted the goats extensively at one time, and undoubtedly this awkward appearing dweller of the remote and inaccessible sections is an animal most park visitors hope to encounter.

Chief feeding grounds during the summer are on the heavily vegetated slopes near forest line. In the early morning hours the goats move out of their nighttime resting places and begin feeding as they climb to higher elevations. They travel in a very leisurely fashion, seldom running, and they select their course with considerable care. An old billy usually takes the lead, the other following along behind in single file. Young goats are “sandwiched” between the adults. In moving across any slope area where the footing is treacherous or where rocks might roll, it is customary for only one goat to cross at a time, the others staying back until it is safe to cross.

Without doubt the characteristic of the mountain goats that excites the most interest and admiration is their ability to travel across steep cliffs and narrow ledges with no apparent difficulty or hesitation. Nor does this trail lead only over perilous rock ridges. The goats may venture out upon the ice fields of some of the glaciers. Even glare ice does not present an impasse, it only serves to slow the progress of these indomitable mountaineers.

The female usually has one or two kids born in late spring. By September they are about half grown, and quite capable of keeping up with their parents in even the most difficult going. They remain with their mother through the first winter. Like most young animals, kids are quite playful.

Apparently the goat population of this area is fairly stable, perhaps increasing slightly under the complete sanctuary afforded by the park. As long ago as 1894, John Muir reckoned that there were over 200 goats on Mount Rainier. Ernest Thompson Seton, in his _Lives of Game Animals_ states that “There are certainly 300 now (1929).” The wildlife census for the park lists from 250-300 goats in 1931, and census reports in recent years indicate from 350-400.

OLYMPIC BLACK BEAR _Ursus americanus altifrontalis_ Elliot

There are two color forms of the black bear in the park—the black and the brown. The all black or mostly black is the phase most commonly observed, but brown individuals may often be seen. The black phase sometimes has a brown patch covering the muzzle and a white spot on the chest. The color ratio is usually about five black to one brown.

_Specimens in park collection:_ None.

The black bear was formerly found over most of wooded North America, but has now become extinct over much of the original range. The Olympic black bear occurs in western Washington, western Oregon, and northwestern California.

In the park it is likely to be encountered anywhere in the timbered regions, with an occasional record coming from above forest line. One record of an unusual nature was obtained several years ago by Mr. Harry Meyers of the Mountaineers Club and Major E. S. Ingraham of Seattle. They reported that while blizzard bound in the crater on the summit of Mount Rainier they saw a black bear walk up to the rocks on the rim of the crater and then disappear in the storm. They suggested that the bear possibly was lost in the storm while on a glacier and instinctively climbed higher and higher until it reached the top of the peak. In October, 1948, a record was obtained of a bear well up on the Paradise Glacier, 6,500 feet. This animal was climbing steadily higher, and disappeared over the crest west of Cowlitz Rocks.

There can be no doubt that the bear is one of the feature attractions of the park. The appearance of one of these animals is a signal for visitors of all ages to come running to get a look. Unfortunately the attention paid to the bear doesn’t always stop at this point, and someone is almost sure to pull out a piece of candy or some other tidbit to see if bruin will eat it. Thus a bear problem is soon in the making. Loving sweets, bacon and grease as he does, the bear cannot be blamed too much if he eats quantities of these items offered him and then makes a shambles of tents and food stores looking for more.

Contrary to popular belief the black bear is not a vicious animal, and in the normal wild state is timid and takes to his heels whenever anything of an unusual nature happens. Sudden loud noises will send him off in a wild stampede. This can certainly be attested to by one visitor whose car was invaded by a bear. Unwittingly the bear sat heavily upon the car’s horn—and simply took out glass, door and all in his mad scramble to get out!

The bear is an expert climber and handles himself with great skill. When frightened the cub will almost always shinny up the nearest tree before looking to see what caused the alarm. The mother bear will often send her youngsters up a tree when she is afraid they may be in danger or when she wants them to “stay put” for a time. Bear cubs in a tree are a fair warning to stay away because the mother is bound to be somewhere close by.
