The Rocky Mountain Wonderland Part 11

Big wild folk do not range afar nor at random, nor do they drift about like gypsies. Most animals range in a small locality,--spend their lives in a comparatively small territory. They are familiar with a small district and thus are able to use it at all times to the best advantage. They know where to find the earliest gra.s.s; where flies are least troublesome; the route over which to retreat in case of attack; and where is the best shelter from the storm.

[Ill.u.s.tration: A DEER IN DEEP SNOW, ROCKY MOUNTAIN NATIONAL PARK]

With the coming of a snow-storm big game commonly move to the most sheltered spot in their district. This may or may not be close to a food-supply. A usual place of refuge is in a cover or sheltered spot on a sunny southern slope,--a place, too, in which the snow will first melt. Immediately after a storm there may often be found a motley collection of local wild folk in a place of this kind. Bunched, the big game hope and wait. Unless the snow is extremely deep they become restless and begin to scatter after two or three days.

There are a number of places in each locality which may offer temporary, or even permanent, relief to snow-hampered game. These are open streams, flood-cleared flats, open spots around springs, wind-cleared places, and openings, large and small, made by snow-slides. During long-lying deep snows the big game generally use every local spot or opening of vantage.

In many regions a fall of snow is followed by days of fair weather.

During these days most of the snow melts; often the earth is almost free of one snow before another fall comes. In places of this kind the game have periods of ease. But in vast territories the snow comes, deepens, and lies deep over the earth for weeks. To endure long-lying deep snows requires special habits or methods. The yarding habit, more or less intensely developed, is common with sheep, elk, deer, and moose of all snowy lands.

The careful yarding habit of the moose is an excellent method of triumphing over deep snow. In early winter, or with the deepening snow, a moose family proceed to a locality where food is abundant; here they restrict themselves to a small stamping-ground,--one of a stone's throw or a few hundred feet radius. Constant tramping and feeding in this limited area compacts the snow in s.p.a.ces and in all the trails so that the animals walk on top of it. Each additional snow is in turn trampled to sustaining compactness.

At first the low-growing herbage is eaten; but when this is buried, and the animals are raised up by added snow, they feed upon shrubs; then on the willow or the birch tops, and sometimes on limbs well up in the trees, which the platform of deeply acc.u.mulated snow enables them to reach. Commonly moose stay all winter in one yard. Sometimes the giving-out of the food-supply may drive them forth. Then they try to reach another yard. But deep snow or wolves may overcome one or all on the way.

During one snowshoe trip through western Colorado I visited seven deer-yards. One of these had been attacked by wolves but probably without result. Apparently five of the others had not as yet been visited by deadly enemies. The seventh and most interesting yard was situated in a deep gorge amid rugged mountains. It was long and narrow, and in it the deer had fed upon withered gra.s.s, plant stalks, and willow twigs. All around the undrifted snow lay deep. The limbless bases of the spruces were set deep in snow, and their lower limbs were pulled down and tangled in it. These trees had the appearance of having been pushed part way up through the snow. In places the cliffs showed their bare brown sides. Entire spruce groves had been tilted to sharp angles by the slipping and dragging snow weight on steep places; among them were tall spruces that appeared like great feathered arrows that had been shot into snowy steeps. The leafless aspens attractively displayed their white and greenish-white skin on limbs that were held just above the snow.

With a curve, the yard shaped itself to the buried stream. It lay between forested and moderately steep mountains that rose high. In this primeval winter scene the deer had faced the slow-going snow in the primitive way. At the upper end of the yard all the snow was trampled to compactness, and over this animals could walk without sinking in. Firm, too, were the surfaces of the much looped and oft trodden trails. The trail nearest to the stream pa.s.sed beneath a number of beautiful snow-piled arches. These arches were formed of outreaching and interlacing arms of parallel growths of willow and birch cl.u.s.ters. The stream gurgled beneath its storm window of rough ice.

I rounded the yard and at the lower end I found the carca.s.ses of the entire herd of deer,--nine in all,--evidently recently killed by a mountain lion. He had eaten but little of their flesh. Wolves had not yet discovered this feast, but a number of Rocky Mountain jays were there. The dark spruces stood waiting! No air stirred. Bright sunlight and bluish pine shadows rested upon the glazed whiteness of the snow.

The flock of cheerful chickadees feeding through the trees knew no tragedy.

The winter food of big game consists of dead gra.s.s, shrubs, twigs, buds and bark of trees, moss, and dry plants. At times gra.s.s dries or cures before the frost comes. When thus cured it retains much nutrition,--is, in fact, unraked hay. If blighted by frost it loses its flavor and most of its food value.

During summer both elk and deer range high on the mountains. With the coming of winter they descend to the foothill region, where the elk collect in large herds, living in yards in case of prolonged deep snow. Deer roam in small herds. Occasionally a herd of the older elk will for weeks live in the comparatively deep snow on northern slopes,--slopes where the snow crusts least. Here they browse off alder and even aspen bark.

The present congestion of elk in Jackson Hole represents an abnormal condition brought about by man. The winter feed on which they formerly lived is devoured by sheep or cattle during the summer; a part of their former winter range is mowed for hay; they are hampered by fences. As a result of these conditions many suffer and not a few starve.

Wolves are now afflicting both wild and tame herds in Jackson Hole.

Apparently the wolves, which formerly were unknown here in winter, have been drawn thither by the food-supply which weak or dead elk afford.

The regular winter home of wild sheep is among the peaks above the limits of tree growth. Unlike elk and deer, the mountain sheep is found in the heights the year round. He may, both in winter and summer, make excursions into the lowlands, but during snowy times he clings to the heights. Here he usually finds a tableland or a ridge that has been freed of snow by the winds. In these snow-free places he can feed and loiter and sometimes look down on unfortunate snow-bound deer and elk.

The bunching habit of big game during periods of extreme cold or deep snow probably confers many benefits. It discourages the attacks of carnivorous enemies, and usually renders such attacks ineffective.

Crowding also gives the greatest warmth with the least burning of fat fuel. The conservation of energy by storm-bound animals is of the utmost importance. Cold and snow make complicated endurance tests; the animals must with such handicaps withstand enemies and sometimes live for days with but little or nothing to eat.

Big game, on occasions, suffer bitterly through a combination of misfortunes. Something may prevent a herd reaching its best shelter, and it must then endure the storm in poor quarters; pursuit may scatter and leave each one stranded alone in a bad place; in such case each will suffer from lonesomeness, even though it endure the cold and defy enemies. Most animals, even those that are normally solitary, appear to want society during emergencies.

A deep snow is sometimes followed by a brief thaw, then by days of extreme cold. The snow crusts, making it almost impossible for big game to move, but encouragingly easy for wolves to travel and to attack. Of course, long periods separate these extremely deadly combinations. Probably the ordinary loss of big game from wolves and mountain lions is less than is imagined.

Some years ago an old Ute Indian told me that during a winter of his boyhood the snow for weeks lay "four ponies deep" over the Rocky Mountains, and that "most elk die, many ponies die, wolves die, and Indian nearly die too." A "Great Snow" of this kind is terrible for wild folk.

Snow and cold sometimes combine to do their worst. The snow covers everything deeply; then follows an unbroken period of extreme cold; the Ice King is again enthroned; the snow fiendishly refuses to melt, and lies for weeks; the endurance of most wild folk becomes exhausted, and birds, herds, and wolves perish. Similar calamities used occasionally to afflict our primitive ancestors.

Over the vast Northwest a feature of the climate is the winter-annihilating Chinook wind. This occasionally saves the people of the wilds when other relief is impossible. The snowy earth is quickly transformed by this warm, dry wind. In a few hours conditions become summer-like. Fortunately, the Chinook often follows a blizzard.

Many a time at the eleventh hour it has dramatically saved the waiting, suffering birds and rescued the snow-buried and starving folk of the wilds.

The beaver and the bear are often benefited by the deep snows which afflict their wild neighbors. During the prolonged hibernating sleep, the bear does not eat, but he commonly needs a thick snowy blanket to keep him comfortable. The beaver has his winter stores on the bottom of the pond beneath the ice. These he reaches from his house by swimming beneath the ice from the house to the food-pile. If the ice is not covered by snow, it may, during a cold winter, freeze thickly, even to the bottom, and thus cause a starving time in the beaver colony.

Deep snow appears not to trouble the "stupidest animal in the woods,"

the porcupine. A deeper snow is for him a higher platform from which the bark on the tree may be devoured. Rabbits, too, appear to fare well during deep snow. This uplift allows them a long feast among the crowded, bud-fruited bush-tops at which they have so often looked in vain.

The chipmunk is not concerned with groundhog day. Last summer he filled his underground granaries with nuts and seeds, and subways connect his underground winter quarters with these stores. But heavy snows, with their excess of water, flood him out of winter quarters in spring earlier than he planned.

One March at the close of a wet snow-fall I went out into a near-by pine grove to see the squirrels. One descended from a high hole to the snow and without trouble located and bored down through the snow to his cone-deposit. With difficulty he climbed up through the heavy snow with a cone. He did not enjoy floundering through the clinging snow to the tree-trunk. But at last up he started with a snow-laden cone, in search of a dry seat on which to eat. After climbing a few feet he tumbled back into the unpleasant snow. In some manner the wet snow on the tree-trunk had caused his downfall. With temper peppery he gathered himself up, and for a moment glared at me as though about to blame me for his troubles. Then, muttering, he climbed up the tree.

Sometimes the chipmunk, and the squirrel also, indulge in hibernating periods of sleep despite their ample stores of convenient food.

The ptarmigan is preeminently the bird of the snows; it is the Eskimo of the bird world. It resides in the land realm of the Farthest North and also throughout the West upon high mountain-tops. In the heights it lives above the limits of tree growth, close to snow-drifts that never melt, and in places above the alt.i.tude of twelve thousand feet.

It is a permanent resident of the heights, and apparently only starvation will drive it to the lowlands. Its winter food consists of seeds of alpine plants and the buds of dwarf arctic willow. This willow is matted, dwarfed, and low-growing. When drifted over, the ptarmigan burrow into the snow and find shelter beneath its flattened growth. Here they are in reach of willow buds.

Buds are freely eaten by many kinds of birds; they are the staff of life of the ptarmigan and often of the grouse. They are sought by rabbits and go in with the browse eaten by big game. Buds of trees and shrubs are a kind of fruit, a concentrated food, much of the nature of nuts or tubers.

The cheerful water-ouzel, even during the winter, obtains much of its food from the bottom of brooks and lakes. The ouzel spends many winter nights in nooks and niches in the bank between the ice and the water.

This is a strange place, though one comparatively safe and sheltered.

In getting into the water beneath the ice, the ouzel commonly finds opportunity at the outlet or the inlet of the lake; sometimes through an opening maintained by spring water. There are usually many entrances into the waters of a frozen brook,--openings by cascades and the holes that commonly remain in the ice over swift waters. Excessive snow or extreme cold may close all entrances and thus exclude the ouzel from both food and water. Down the mountain or southward the ouzel then goes.

Woodp.e.c.k.e.rs and chickadees fare well despite any combination of extreme cold or deep snow. For the most part their food is the larvae or the eggs that are deposited here and there in the tree by hundreds of kinds of insects and parasites which afflict trees. Nothing except a heavy sleet appears to make these food-deposits inaccessible.

Most birds spend the winter months in the South. But bad conditions may cause resident birds and animals to migrate, even in midwinter.

Extremely unfavorable winters in British Columbia will cause many birds that regularly winter in that country to travel one or two thousand miles southward into the mountains of Colorado. Among the species which thus modify their habits are the red crossbill, the redpoll, the Lapland longspur, and the snowy owl.

After all, there are points in common between the animal life of the wild and the human life of civilization. Man and the wild animals alike find their chief occupation in getting food or in keeping out of danger. Change plays a large part in the life of each, and abnormal conditions affect them both. Let a great snow come in early winter, and both will have trouble, and both for a time may find the struggle for existence severe.

The primitive man slaughtered storm-bound animals, but civilized man rescues them. A deep snow offers a good opportunity for more intimate acquaintance with our wild neighbors. And snowy times, too, are good picture-taking periods. In snowy times, if our wild neighbors already respect us, tempting food and encouraging hunger will place big, shy, and awkward country fellows and nervous birds close to the camera and close to our hearts.

My Chipmunk Callers

My Chipmunk Callers

About a score of chipmunks have their homes in my yard. They are delightfully tame and will climb upon my head or shoulder, eat nuts from my hand, or go into my pockets after them. At times three or four make it lively for me. One day I stooped to give one some peanuts.

While he was standing erect and taking them from my fingers, a strange dog appeared. At once all the chipmunks in the yard gave a chattering, scolding alarm-cry and retreated to their holes. The one I was feeding dashed up into my coat pocket. Standing up with fore paws on the edge of the pocket, and with head thrust out, he gave the dog a tempestuous scolding. This same chipmunk often played upon the back of Scotch, my collie. Occasionally he stood erect on Scotch to sputter out an alarm-cry and to look around when something aroused his suspicions.

Chipmunks are easily tamed and on short acquaintance will come to eat from one's hand. Often they come into my cabin for food or for paper to use for bedding. Occasionally one will sit erect upon my knee or shoulder, sometimes looking off intently into the yard; at other times apparently seeing nothing, but wrapped in meditation. More often, however, they are storing peanuts in their pouches or deliberately eating a kernel. Rarely is the presence of one agreeable to another, and when four or five happen to call at the same time, they sometimes forget their etiquette and I am the centre of a chipmunk scrimmage.

Once five callers came, each stringing in behind another. Just as the fifth came in the door, there was a dispute among the others and one started to retreat. Evidently he did not want to go, for he retreated away from the open door. As number two started in pursuit of him, number three gave chase to number two. After them started number four, and the fifth one after all the others. The first one, being closely pressed and not wanting to leave the room, ran round the centre table, and in an instant all five were racing single file round the table.

After the first round they became excited and each one went his best.

The circle they were following was not large, and the floor was smooth. Presently the rear legs of one skidded comically, then the fore feet of another; and now and then one lost his footing and rolled entirely over, then arose, looking surprised and foolish, but with a leap entered the circle and was again at full speed.

[Ill.u.s.tration: ENTERTAINING A CHIPMUNK CALLER]

I enjoy having them about, and spend many a happy hour watching them or playing with them. They often make a picnic-ground of my porch, and now and then one lies down to rest upon one of the log seats, where, outstretched, with head up and one fore paw extended leisurely upon the log, he looks like a young lion.

Often they climb up and scamper over the roof of my cabin; but most of their time on the roof is spent in dressing their fur or enjoying long, warm sun baths. Frequently they mount the roof early in the morning, even before sunrise. I am sometimes awakened at early dawn by a chipmunk mob that is having a lively time upon the roof.
