The Minds and Manners of Wild Animals: A Book of Personal Observations

KEEN BIRDS AND DULL MEN

If all men could know how greatly the human species varies from highest to lowest, and how the minds and emotions of the lowest men parallel and dove-tail with those of the highest quadrupeds and birds, we might be less obsessed with our own human ego, and more appreciative of the intelligence of animals.

A thousand times in my life my blood has been brought to the boiling point by seeing or reading of the cruel practices of ignorant and vicious men toward animals whom they despised because of their alleged standing "below man." By his vicious and cruel nature, many a man is totally unfitted to own, or even to associate with, dogs, horses and monkeys. Many persons are born into the belief that every man is necessarily a "lord of creation," and that all animals per se are man's lawful prey. In the vicious mind that impression increases with age. Minds of the better classes can readily learn by precept or by reasoning from cause to effect the duty of man to observe and defend the God- given rights of animals.

It was very recently that I saw on the street a group that represented man's attitude toward wild animals. It consisted of an unclean and vicious-looking man in tramp's clothing, grinding an offensive hand-organ and domineering over a poor little terrorized "ringtail" monkey. The wretched mite from the jungle was encased in a heavy woolen straight-jacket, and there was a strap around its loins to which a stout cord was attached, running to the Root of All Evil. The pavement was hot, but there with its bare and tender feet on the hot concrete, the sad-eyed little waif painfully moved about, peering far up into the faces of passers-by for sympathy, but all the time furtively and shrinkingly watching its tormentor. Every now and then the hairy old tramp would jerk the monkey's cord, each time giving the frail creature a violent bodily wrench from head to foot. I think that string was jerked about forty times every hour.

And that exhibition of monkey torture in a monkey hell continues in summer throughout many states of our country,—because "it pleases the children!" The use of monkeys with hand-organs is a cruel outrage upon the monkey tribe, and no civilized state or municipality should tolerate it. I call upon all humane persons to put an end to it.

As an antidote to our vaulting human egotism, we should think often upon the closeness of mental contact between the highest animals and the lowest men. In drawing a parallel between those two groups, there are no single factors more valuable than the home, and the family food supply. These hark back to the most primitive instincts of the vertebrates. They are the bedrock foundations upon which every species rests. As they are stable or unstable, good or bad, so lives or dies the individual, and the species also.

In employing the term "highest animals" I wish to be understood as referring to the warm-blooded vertebrates, and not merely the apes and monkeys that both structurally and mentally are nearest to man.

Throughout my lifetime I have been by turns amazed, entertained and instructed by the marvelous intelligence and mechanical skill of small mammals in constructing burrows, and of certain birds in the construction of their nests. Today the hanging nest of the Baltimore oriole is to me an even greater wonder than it was when I first saw one over sixty years ago. Even today the mechanical skill involved in its construction is beyond my comprehension. My dull brain can not figure out the processes by which the bird begins to weave its hanging purse at the tip end of the most unstable of all earthly building sites,—a down-hanging elm-tree branch that is swayed to and fro by every passing breeze. The situation is so "impossible" that thus far no moving picture artist has ever caught and recorded the process.

Take in your hand a standard oriole nest, and examine it thoroughly. First you will note that it is very strong, and thoroughly durable. It can stand the lashings of the fiercest gales that visit our storm-beaten shore.

How long would it take a man to unravel that nest, wisp by wisp, and resolve it into a loose pile of materials? Certainly not less than an entire day. Do you think that even your skilful fingers,— unassisted by needles,—could in two days, or in three, weave of those same materials a nest like that, that would function as did the original? I doubt it. The materials consist of long strips of the thin inner bark of trees, short strings, and tiny grass stems that are long, pliable and tough. Who taught the oriole how to find and to weave those rare and hard-to-find materials? And how did it manage all that weaving with its beak only? Let the wise ones answer, if they can; for I confess that I can not!

Down in Venezuela, in the delta of the Orinoco River, and elsewhere, lives a black and yellow bird called the giant cacique (pronounced cay-seek'), which as a nest-builder far surpasses our oriole. Often the cacique's hanging nest is from four to six feet long. The oriole builds to escape the red squirrels, but the cacique has to reckon with the prehensile-tailed monkeys.

Sometimes a dozen caciques will hang their nests in close proximity to a wasps' nest, as if for additional protection. A cacique's nest hangs like a grass rope, with a commodious purse at its lower end, entered by a narrow perpendicular slit a foot or so above the terminal facilities. It is impossible to achieve one of these nests without either shooting off the limb to which it hangs, or felling the tree. If it hangs low enough a charge of coarse shot usually will cut the limb, but if high, cutting it down with a rifle bullet is a more serious matter.

To our Zoological Park visitors the African weaver birds are a wonder and a delight. Orioles and caciques do not build nests in captivity, but the weavers blithely transfer their activities to their spacious cage in our tropical-bird house. The bird-men keep them supplied with raffia grass, and they do the rest. Fortunately for us, they weave nests for fun, and work at it all the year round! Millions of visitors have watched them doing it. To facilitate their work the upper half of their cage is judiciously supplied with tree-branches of the proper size and architectural slant. The weaving covers many horizontal branches. Sometimes a group of nests will be tied together in a structure four feet long; and it branches up, or down, or across, seemingly without rhyme or reason.

Some of the weavers, which inhabit Africa, Malayana and Australia, are "communal" nest-builders. They build colonies of nests, close together. Imagine twenty-five or more Baltimore orioles massing their nests together on one side of a single tree, in a genuine village. That is the habit of some of the weaver birds;—and this brings us to what is called the most wonderful of all manifestations of house-building intelligence among birds. It is the community house of the little sociable weaver-bird of South Africa (Philetoerus socius). Having missed seeing the work of this species save in museums, I will quote from the Royal Natural History, written by the late Dr. Richard Lydekker, an excellent description: —This species congregates in large flocks, many pairs incubating their eggs under the same roof, which is composed of cartloads of grass piled on a branch of some camel- thorn tree in one enormous mass of an irregular umbrella shape, looking like a miniature haystack and almost solid, but with the under surface (which is nearly flat) honeycombed all over with little cavities, which serve not only as places for incubation, but also as a refuge against rain and wind.

"They are constantly being repaired by their active little inhabitants. It is curious that even the initiated eye is constantly being deceived by these dome-topped structures, since at a distance they closely resemble native huts. The nesting- chambers themselves are warmly lined with feathers."

Here must we abruptly end our exhibits of the intelligence of a few humble little birds as fairly representative of the wonderful mental ability and mechanical skill so common in the ranks of the birds of the world. It would be quite easy to write a volume on The Architectural Skill of Birds!

Now, let us look for a moment into the house-building intelligence and skill of some of the lower tribes of men. Out of the multitude of exhibits available I will limit myself to three, widely separated. In the first place, the habitations of the savage and barbaric tribes are usually the direct result of their own mental and moral deficiencies. The Eskimo is an exception, because his home and its location are dictated by the hard and fierce circumstances which dictate to him what he must do. Often he is compelled to move as his food supply moves. The Cliff-Dweller Indian of the arid regions of the Southwest was forced to cliff- dwell, in order to stave off extermination by his enemies. Under that spur he became a wonderful architect and engineer.

For present purposes we are concerned with three savage tribes which might have been rich and prosperous agriculturists or herdsmen had they developed sufficient intelligence to see the wisdom of regular industry.

Consider first the lowest of three primitive tribes that inhabit the extreme southern point of Patagonia, whose real estate holdings front on the Strait of Magellan. That region is treeless, rocky, windswept, cold and inhospitable. I can not imagine a place better fitted for an anarchist penal colony. North of it lie plains less rigorous, and by degrees less sterile, and finally there are lands quite habitable by cattle-and-crop-growing men.

But those three tribes elect to stick to the worst spot in South America. The most primitive is the tribe of "canoe Indians" of Tierra del Fuego, which probably represents the lowest rung of the human ladder. Beside them the cave men of 30,000 years ago were kings and princes. Their only rivals seem to be the Poonans of Central Borneo, who, living in a hot country, make no houses or shelters of any kind, and have no clothing but a long strip of bark cloth around the loins.

The Fuegians have long been known to mariners and travellers. They inhabit a region that half the year is bleak, cold and raw, but they make nothing save the rudest of the rude in canoes—of rough slabs tied together and caulked with moss,—and rough bone- pointed spears, bows, arrows and paddles. Their only clothing consists of skins of the guanacos loosely hung from the neck, and flapping over the naked and repulsive body. They make no houses, and on shore their only shelters from the wind and snow and chilling rains are rabbit-like forms of brush, broken off by hand.

These people are lower in the scale of intelligence than any wild animal species known to me; for they are mentally too dull and low to maintain themselves on a continuing basis. Their hundred years of contact with man has taught them little; and numerically they are decreasing so rapidly that the world will soon see the absolute finish of the tribe.

In the best of the three tribes, the Tchuelclus, the birth rate is so low that within recent times the tribe has diminished from about 5,000 to a remnant of about 500.

Now, have those primitive creatures "immortal souls?" Are they entitled to call chimpanzees, elephants, bears and dogs "lower animals?" Do they "think," or "reason," any more than the animals I have named?

It is a far cry from the highest to the lowest of the human race; and we hold that the highest animals intellectually are higher than the lowest men.

Now go with me for a moment to the lofty and dense tropical forest in the heart of the Territory of Selangor, in the Malay Peninsula. That forest is the home of the wild elephant, rhinoceros and sladang. And there dwells a jungle tribe called the Jackoons, some members of which I met at their family home, and observed literally in their own ancestral tree. Their house was not wholly bad, but it might have been 100 per cent better. It was merely a platform of small poles, placed like a glorified bird's nest in the spreading forks of a many-branched tree, about twenty feet from the ground. The main supports were bark-lashed to the large branches of the family tree. Over this there was a rude roof of long grass, which had a fairly intelligent slope. As a shelter from rain, the Jackoon house left much to be desired. The scanty loin cloths of the habitants knew no such thing as wash-day or line. With all its drawbacks, however, this habitation was far more adequate to the needs of its builders than the cold brush rabbit-forms of the Patagonian canoe Indians.

We now come to a tribe which has reduced the problem of housing and home life to its lowest common denominator. The Poonans of Central Borneo, discovered and described by Carl Bock, build no houses of any kind, not even huts of green branches; and their only overture toward the promotion of personal comfort in the home is a five-foot grass mat spread upon the sodden earth, to lie upon when at rest. And this, in a country where in the so-called "dry season" it rains half the time, and in the "wet season" all the time.

The Poonans have rudely-made spears for taking the wild pig, deer and smaller game, their clothes consist of bark cloth, around the loins only. They know no such thing as agriculture, and they live off the jungle.

It was said some years ago that a similarly primitive jungle tribe of Ceylon, known as the Veddahs, could count no more than five, that they could not comprehend "day after to-morrow," and that their vocabulary was limited to about 200 words.

It is very probable that the language of the Poonans and the Jackoons is equally limited. And what are we to conclude from all the foregoing? Briefly, I should say that the architectural skill of the orioles, the caciques and the weaver birds is greater than that of the South Patagonia native, the Jackoon and the Poonan. I should say that those bird homes yield to their makers more comfort and protection, and a better birth-rate, than are yielded by the homes of those ignorant, unambitious and retrogressive tribes of men now living and thinking, and supposed to be possessed of reasoning powers. If the whole truth could be known, I believe it would be found that the stock of ideas possessed and used by the groups of highly-endowed birds would fully equal the ideas of such tribes of simple-minded men as those mentioned. If caught young, those savages could be trained by civilized men, and taught to perform many tricks, but so can chimpanzees and elephants.

Curiously enough, it is a common thing for even the higher types of civilized men to make in home-building just as serious mistakes as are made by wild animals and savages. For example, among the men of our time it is a common mistake to build in the wrong place, to build entirely too large or too ugly, and to build a Colossal Burden instead of a real Home. From many a palace there stands forth the perpetual question: "Why did he do it?"

Any reader who at any time inclines toward an opinion that the author is unduly severe on the mentality of the human race, even as it exists today in the United States, is urged to read in the Scientific Monthly for January, 1922, an article by Professor L. M. Tennan entitled "Adventures in Stupidity.—A Partial Analysis of the Intellectual Inferiority of a College Student." He should particularly note the percentages on page 34 in the second paragraph under the subtitle "The Psychology of Stupidity."
