Chapter Eleven. Squirrels - Book of zoology for boys by Mayne Reid
These pretty little animals are widely distributed over the earth; though to this remark Australia seems to form an exception, since no species has yet been discovered there. However, there is much of that great island continent yet to be explored; and perhaps it may turn out that Australia has its squirrels, as well as other parts of the world—no doubt squirrels with pouches.
In number of species—and also of individuals, it may be added—America excels all other countries, and the great forests of North America may be regarded as the head-quarters of the squirrel tribe; but, if we give precedence to size, the squirrels of the East Indian countries are entitled to the first place.
Animals known as Squirrels are of three very distinct kinds—viz., Squirrels, properly so called; Ground Squirrels: and Flying Squirrels. These three kinds are very naturally separated into three different genera; but the closet naturalists, not content with this simple division, have again subdivided them into other sub-genera, using very difficult names to distinguish them. In our little sketch we shall simply call them by the three names above-mentioned.
The Squirrels, properly so called, are not only tree-climbers, but, as every one knows, dwell habitually upon trees, and there make their nests and their home. And perfectly at home they are among the highest branches; for under no circumstances do they ever miss their footing, or are they in the slightest danger of falling. In fact, they can not only run with the greatest agility along the branches, but equally well with their backs downward; and can spring from branch to branch, and also from tree to tree, over wide intervals of many yards. They can also leap down from the tops of the tallest trees to the earth—a feat often witnessed by squirrel-hunters—and do so without the appearance of having received the slightest injury; for, without pausing a moment on the ground, they continue their flight towards some other tree, where they expect to find better shelter from the short gun or rifle of their human enemy.
The squirrel builds a nest in the tree, similar to that of some birds; but they have also in the same tree a more secure retreat in case of being pursued. This is a hole in the trunk or one of the larger limbs—some natural excavation caused by the decaying of a branch—in short, what is termed a “knot hole,” which is common in many kinds of timber. In this hole the squirrel usually lays up its store of winter food, consisting of nuts, beech-mast, etcetera; and here it takes refuge when hunted, finding the tree-cave a safe asylum. Unless decoyed out again, or, which often happens, frightened out again, by rubbing the trunk with a piece of stick, the squirrel must escape scot-free nine times out of ten, since no hunter would think of felling a huge tree to procure so insignificant a reward as the carcass of a squirrel; and without felling the tree, and splitting it up, too, the creature could not be reached. Various devices, however, are practised to decoy it forth; and these, unfortunately for the little refugee, too often succeed.
The squirrels are the life of the American woods—indeed, a journey through these great forests would often be very monotonous were it not enlivened by the presence and gambols of these beautiful creatures; and in the depth of winter, when the squirrels keep within their dark tree-caves, the solitude of the forest seems redoubled. But even during frost and snow, when the weather is fine and the sun shining brightly, a few will be seen venturing forth, as if to take an airing.
A great many species exist in the forests of North America; sometimes only one, and sometimes several, occupy the same district. They are of different colours and sizes—some as small as the common squirrel of England, while several species are three or four times as large. Some are grey, others brown grey, several species of a fox red, and those esteemed the most beautiful are of a uniform jet black. Several new species have lately been found in the forests of Oregon and California.
Their habits are all nearly alike; but to one species of Grey Squirrel belongs a habit as distinct as it is singular. This is their habit of collecting together in immense flocks of many thousands, and migrating over vast tracts of country, crossing broad rapid rivers, and staying at no obstacle. The object of this migration is not known, only that it appears to be the result of some impulse—such as excites to a similar movement the springboks of South Africa, the buffaloes of North America, and the passenger pigeons.
In Europe the squirrel is represented by the Common Squirrel of our own woods, and which is found throughout the whole of Northern Europe and Asia, wherever there are trees. Although of a reddish colour in England, as well as in France, it assumes different hues, according to the different countries it inhabits; and in the more northern latitudes it is quite grey. Another European species, distinct from the English squirrel, is a denizen of the Pyrenees and the Alps of Dauphiné.
The Palm Squirrel is a beautiful species belonging to the tropical parts of Africa and India, and dwelling principally upon the palm trees—as its name imports.
Another, known as the Barbary Squirrel, belongs to North Africa, and is also a dweller upon palm trees.
The largest, and perhaps the most richly-coated of the tribe, is the Malabar Squirrel of India, which is as large as a domestic cat. It also haunts among palm trees, and is fond of the milk of the cocoa-nut, either in a liquid or solid state.
There are squirrels also in Eastern Africa. India has several species, and the great islands of Madagascar, Ceylon, Java, Borneo, Sumatra, etcetera, have each one or more species of large and beautiful squirrels.
The Ground Squirrels differ from the true squirrels in several respects, though the chief difference lies in the fact that the former make their nest or lair upon the ground, while the latter universally lodge themselves aloft among the branches. The Ground Squirrels can climb, and appear to ascend trees almost as nimbly as their congeners; but they rarely do so unless when pursued, and then but seldom go beyond the lower forks or branches. Their nest is usually in some hole or cavity among the roots, though several species have been lately discovered in rocky regions, dwelling in the crevices of rocks. They approach in habits to the marmot tribe, and seem to link the tree squirrels with these last. Usually, these ground squirrels are striped longitudinally with black, red, and white stripes, giving them a fine appearance; and the species are of different dimensions, from that of the ordinary squirrel to the size of a mouse. In America, for a long time, but one kind was supposed to exist; but latterly a great number of species have been observed and described: denizens of the far West—of the prairies, and remote valleys of the Rocky Mountains.
The African species of ground squirrel, already mentioned as the Palm Squirrel, has its dwelling among the palm trees, on the fruit and roots of which—especially that of the date-palm—it subsists. It is also an inhabitant of India, where there is at least one other species of palm ground squirrel.
In Europe, and throughout the whole of Northern Asia, the ground squirrels are represented by the burunduk—a very interesting little species, quite similar in habits to those of North America.
The Flying Squirrels are the last of the group. These are the most singular of all, and resemble great bats more than squirrels. They possess the power, not exactly of flight, but of making very long leaps from a higher to a lower level, so long that they might almost be regarded as flights. They can pass from one tree to another standing more than a hundred yards apart, and this without descending more than a few feet below the level from which they started. This feat they are enabled to perform by means of a broad membrane that extends from the skin of their fore-legs to that of their thighs, and which, when stretched out, endows them with the properties of a parachute. Their bodies, too, have a flattened shape like the bats; and this also helps to sustain them in the air.
They are true squirrels, however, living upon trees, as the common squirrels do, and looking very like the latter, notwithstanding their winged legs. In one point, however, they differ essentially from the common squirrels; and that is, they are nocturnal in their habits. In the daytime they are never seen, except by accident; but in the twilight, and during a clear night, they may be observed making their long leaps from tree to tree, through the glades or along the edges of the forest. There are several species inhabiting the forests of America, and of late California has yielded several new ones. In the tropical forests of America there are several large species, and the Old World has its flying squirrel in the Polatouka, which inhabits the pine forests of Northern Europe and Asia.
The largest species of these singular quadrupeds appears to belong to the Oriental Islands—to Java, Sumatra, the Philippines, and Moluccas, or Spice Islands, as also to Japan. The great Teguan, or flying squirrel of the Moluccas, is in reality as large as a cat!
The singular Ay-ay of Madagascar is sometimes classed among the squirrels and sometimes among the lemurs. It certainly bears a great resemblance to the squirrel family; but the habits of all animals belonging to Madagascar are so little known that it is difficult to assign them to that exact genus in which Nature intended they should be placed.
