Ways of Wood Folk Part 5

If on a lake sh.o.r.e, where the rise of water is never great, the beaver's house is four or five feet high. On streams subject to freshets they may be two or three times that height. As in the case of the musquash (or muskrat), a strange instinct guides the beaver as to the height of his dwelling. He builds high or low, according to his expectations of high or low water; and he is rarely drowned out of his dry nest.

Sometimes two or three families unite to build a single large house, but always in such cases each family has its separate apartment. When a house is dug open it is evident from the different impressions that each member of the family has his own bed, which he always occupies.

Beavers are exemplary in their neatness; the house after five months'

use is as neat as when first made.

All their building is primarily a matter of instinct, for a tame beaver builds miniature dams and houses on the floor of his cage.

Still it is not an uncontrollable instinct like that of most birds; nor blind, like that of rats and squirrels at times. I have found beaver houses on lake sh.o.r.es where no dam was built, simply because the water was deep enough, and none was needed. In vacation time the young beavers build for fun, just as boys build a dam wherever they can find running water. I am persuaded also (and this may explain some of the dams that seem stupidly placed) that at times the old beavers set the young to work in summer, in order that they may know how to build when it becomes necessary. This is a hard theory to prove, for the beavers work by night, preferably on dark, rainy nights, when they are safest on land to gather materials. But while building is instinctive, skilful building is the result of practice and experience. And some of the beaver dams show wonderful skill.

[Ill.u.s.tration]

There is one beaver that never builds, that never troubles himself about house, or dam, or winter's store. I am not sure whether we ought to call him the genius or the lazy man of the family. The bank beaver is a solitary old bachelor living in a den, like a mink, in the bank of a stream. He does not build a house, because a den under a cedar's roots is as safe and warm. He never builds a dam, because there are deep places in the river where the current is too swift to freeze. He finds tender twigs much juicier, even in winter, than stale bark stored under water. As for his telltale tracks in the snow, his wits must guard him against enemies; and there is the open stretch of river to flee to.

There are two theories among Indians and trappers to account for the bank beaver's eccentricities. The first is that he has failed to find a mate and leaves the colony, or is driven out, to lead a lonely bachelor life. His conduct during the mating season certainly favors this theory, for never was anybody more diligent in his search for a wife than he. Up and down the streams and alder brooks of a whole wild countryside he wanders without rest, stopping here and there on a gra.s.sy point to gather a little handful of mud, like a child's mud pie, all patted smooth, in the midst of which is a little strong smelling musk. When you find that sign, in a circle of carefully trimmed gra.s.s under the alders, you know that there is a young beaver on that stream looking for a wife. And when the young beaver finds his pie opened and closed again, he knows that there is a mate there somewhere waiting for him. But the poor bank beaver never finds his mate, and the next winter must go back to his solitary den. He is much more easily caught than other beavers, and the trappers say it is because he is lonely and tired of life.

The second theory is that generally held by Indians. They say the bank beaver is lazy and refuses to work with the others; so they drive him out. When beavers are busy they are very busy, and tolerate no loafing. Perhaps he even tries to persuade them that all their work is unnecessary, and so shares the fate of reformers in general.

While examining the den of a bank beaver last summer another theory suggested itself. Is not this one of the rare animals in which all the instincts of his kind are lacking? He does not build because he has no impulse to build; he does not know how. So he represents what the beaver was, thousands of years ago, before he learned how to construct his dam and house, reappearing now by some strange freak of heredity, and finding himself wofully out of place and time. The other beavers drive him away because all gregarious animals and birds have a strong fear and dislike of any irregularity in their kind. Even when the peculiarity is slight--a wound, or a deformity--they drive the poor victim from their midst remorselessly. It is a cruel instinct, but part of one of the oldest in creation, the instinct which preserves the species. This explains why the bank beaver never finds a mate; none of the beavers will have anything to do with him.

This occasional lack of instinct is not peculiar to the beavers. Now and then a bird is hatched here in the North that has no impulse to migrate. He cries after his departing comrades, but never follows. So he remains and is lost in the storms of winter.

There are few creatures in the wilderness more difficult to observe than the beavers, both on account of their extreme shyness and because they work only by night. The best way to get a glimpse of them at work is to make a break in their dam and pull the top from one of their houses some autumn afternoon, at the time of full moon. Just before twilight you must steal back and hide some distance from the dam. Even then the chances are against you, for the beavers are suspicious, keen of ear and nose, and generally refuse to show themselves till after the moon sets or you have gone away. You may have to break their dam half a dozen times, and freeze as often, before you see it repaired.

It is a most interesting sight when it comes at last, and well repays the watching. The water is pouring through a five-foot break in the dam; the roof of a house is in ruins. You have rubbed yourself all over with fir boughs, to destroy some of the scent in your clothes, and hidden yourself in the top of a fallen tree. The twilight goes; the moon wheels over the eastern spruces, flooding the river with silver light. Still no sign of life. You are beginning to think of another disappointment; to think your toes cannot stand the cold another minute without stamping, which would spoil everything, when a ripple shoots swiftly across the pool, and a big beaver comes out on the bank. He sits up a moment, looking, listening; then goes to the broken house and sits up again, looking it all over, estimating damages, making plans. There is a commotion in the water; three others join him--you are warm now.

Meanwhile three or four more are swimming about the dam, surveying the damage there. One dives to the bottom, but comes up in a moment to report all safe below. Another is tugging at a thick pole just below you. Slowly he tows it out in front, balances a moment and lets it go--_good!_--squarely across the break. Two others are cutting alders above; and here come the bushes floating down. Over at the damaged house two beavers are up on the walls, raising the rafters into place; a third appears to be laying on the outer covering and plastering it with mud. Now and then one sits up straight like a rabbit, listens, stretches his back to get the kinks out, then drops to his work again.

It is brighter now; moon and stars are glimmering in the pool. At the dam the sound of falling water grows faint as the break is rapidly closed. The houses loom larger. Over the dome of the one broken, the dark outline of a beaver pa.s.ses triumphantly. Quick work that. You grow more interested; you stretch your neck to see--_splash_! A beaver gliding past has seen you. As he dives he gives the water a sharp blow with his broad tail, the danger signal of the beavers, and a startling one in the dead stillness. There is a sound as of a stick being plunged end first into the water; a few eddies go running about the pool, breaking up the moon's reflection; then silence again, and the lap of ripples on the sh.o.r.e.

You can go home now; you will see nothing more to-night. There's a beaver over under the other bank, in the shadow where you cannot see him, just his eyes and ears above water, watching you. He will not stir; nor will another beaver come out till you go away. As you find your canoe and paddle back to camp, a ripple made by a beaver's nose follows silently in the shadow of the alders. At the bend of the river where you disappear, the ripple halts a while, like a projecting stub in the current, then turns and goes swiftly back. There is another splash; the builders come out again; a dozen ripples are scattering star reflections all over the pool; while the little wood folk pause a moment to look at the new works curiously, then go their ways, shy, silent, industrious, through the wilderness night.

VII. CROW-WAYS.

[Ill.u.s.tration]

The crow is very much of a rascal--that is, if any creature can be called a rascal for following out natural and rascally inclinations. I first came to this conclusion one early morning, several years ago, as I watched an old crow diligently exploring a fringe of bushes that grew along the wall of a deserted pasture. He had eaten a clutch of thrush's eggs, and carried off three young sparrows to feed his own young, before I found out what he was about. Since then I have surprised him often at the same depredations.

An old farmer has a.s.sured me that he has also caught him tormenting his sheep, lighting on their backs and pulling the wool out by the roots to get fleece for lining his nest. This is a much more serious charge than that of pulling up corn, though the latter makes almost every farmer his enemy.

Yet with all his rascality he has many curious and interesting ways.

In fact, I hardly know another bird that so well repays a season's study; only one must be very patient, and put up with frequent disappointments if he would learn much of a crow's peculiarities by personal observation. How shy he is! How cunning and quick to learn wisdom! Yet he is very easily fooled; and some experiences that ought to teach him wisdom he seems to forget within an hour. Almost every time I went shooting, in the old barbarian days before I learned better, I used to get one or two crows from a flock that ranged over my hunting ground by simply hiding among the pines and calling like a young crow. If the flock was within hearing, it was astonishing to hear the loud chorus of _haw-haws_, and to see them come rushing over the same grove where a week before they had been fooled in the same way. Sometimes, indeed, they seemed to remember; and when the pseudo young crow began his racket at the bottom of some thick grove they would collect on a distant pine tree and _haw-haw_ in vigorous answer.

But curiosity always got the better of them, and they generally compromised by sending over some swift, long-winged old flier, only to see him go tumbling down at the report of a gun; and away they would go, screaming at the top of their voices, and never stopping till they were miles away. Next week they would do exactly the same thing.

Crows, more than any other birds, are fond of excitement and great crowds; the slightest unusual object furnishes an occasion for an a.s.sembly. A wounded bird will create as much stir in a flock of crows as a railroad accident does in a village. But when some prowling old crow discovers an owl sleeping away the sunlight in the top of a great hemlock, his delight and excitement know no bounds. There is a suppressed frenzy in his very call that every crow in the neighborhood understands. _Come! come! everybody come!_ he seems to be screaming as he circles over the tree-top; and within two minutes there are more crows gathered about that old hemlock than one would believe existed within miles of the place. I counted over seventy one day, immediately about a tree in which one of them had found an owl; and I think there must have been as many more flying about the outskirts that I could not count.

At such times one can approach very near with a little caution, and attend, as it were, a crow caucus. Though I have attended a great many, I have never been able to find any real cause for the excitement. Those nearest the owl sit about in the trees cawing vociferously; not a crow is silent. Those on the outskirts are flying rapidly about and making, if possible, more noise than the inner ring.

The owl meanwhile sits blinking and staring, out of sight in the green top. Every moment two or three crows leave the ring to fly up close and peep in, and then go screaming back again, hopping about on their perches, cawing at every breath, nodding their heads, striking the branches, and acting for all the world like excited stump speakers.

The din grows louder and louder; fresh voices are coming in every minute; and the owl, wondering in some vague way if he is the cause of it all, flies off to some other tree where he can be quiet and go to sleep. Then, with a great rush and clatter, the crows follow, some swift old scout keeping close to the owl and screaming all the way to guide the whole cawing rabble. When the owl stops they gather round again and go through the same performance more excitedly than before.

So it continues till the owl finds some hollow tree and goes in out of sight, leaving them to caw themselves tired; or else he finds some dense pine grove, and doubles about here and there, with that shadowy noiseless flight of his, till he has thrown them off the track. Then he flies into the thickest tree he can find, generally outside the grove where the crows are looking, and sitting close up against the trunk blinks his great yellow eyes and listens to the racket that goes sweeping through the grove, peering curiously into every thick pine, searching everywhere for the lost excitement.

The crows give him up reluctantly. They circle for a few minutes over the grove, rising and falling with that beautiful, regular motion that seems like the practice drill of all gregarious birds, and generally end by collecting in some tree at a distance and _hawing_ about it for hours, till some new excitement calls them elsewhere.

Just why they grow so excited over an owl is an open question. I have never seen them molest him, nor show any tendency other than to stare at him occasionally and make a great noise about it. That they recognize him as a thief and cannibal I have no doubt. But he thieves by night when other birds are abed, and as they practise their own thieving by open daylight, it may be that they are denouncing him as an impostor. Or it may be that the owl in his nightly prowlings sometimes s.n.a.t.c.hes a young crow off the roost. The great horned owl would hardly hesitate to eat an old crow if he could catch him napping; and so they grow excited, as all birds do in the presence of their natural enemies. They make much the same kind of a fuss over a hawk, though the latter easily escapes the annoyance by flying swiftly away, or by circling slowly upward to a height so dizzy that the crows dare not follow.

In the early spring I have utilized this habit of the crows in my search for owls' nests. The crows are much more apt to discover its whereabouts than the most careful ornithologist, and they gather about it frequently for a little excitement. Once I utilized the habit for getting a good look at the crows themselves. I carried out an old stuffed owl, and set it up on a pole close against a great pine tree on the edge of a grove. Then I lay down in a thick clump of bushes near by and _cawed_ excitedly. The first messenger from the flock flew straight over without making any discoveries. The second one found the owl, and I had no need for further calling. _Haw! haw!_ he cried deep down in his throat--_here he is! here's the rascal!_ In a moment he had the whole flock there; and for nearly ten minutes they kept coming in from every direction. A more frenzied lot I never saw. The _hawing_ was tremendous, and I hoped to settle at last the real cause and outcome of the excitement, when an old crow flying close over my hiding place caught sight of me looking out through the bushes. How he made himself heard or understood in the din I do not know; but the crow is never too excited to heed a danger note. The next moment the whole flock were streaming away across the woods, giving the scatter-cry at every flap.

There is another way in which the crows' love of variety is manifest, though in a much more dignified way. Occasionally a flock may be surprised sitting about in the trees, deeply absorbed in watching a performance--generally operatic--by one of their number. The crow's chief note is the hoa.r.s.e _haw, haw_ with which everybody is familiar, and which seems capable of expressing everything, from the soft chatter of going to bed in the pine tops to the loud derision with which he detects all ordinary attempts to surprise him. Certain crows, however, have unusual vocal abilities, and at times they seem to use them for the entertainment of the others. Yet I suspect that these vocal gifts are seldom used, or even discovered, until lack of amus.e.m.e.nt throws them upon their own resources. Certain it is that, whenever a crow makes any unusual sounds, there are always several more about, _hawing_ vigorously, yet seeming to listen attentively. I have caught them at this a score of times.

One September afternoon, while walking quietly through the woods, my attention was attracted by an unusual sound coming from an oak grove, a favorite haunt of gray squirrels. The crows were cawing in the same direction; but every few minutes would come a strange cracking sound--_c-r-r-rack-a-rack-rack_, as if some one had a giant nutcracker and were snapping it rapidly. I stole forward through the low woods till I could see perhaps fifty crows perched about in the oaks, all very attentive to something going on below them that I could not see.

Not till I had crawled up to the brush fence, on the very edge of the grove, and peeked through did I see the performer. Out on the end of a long delicate branch, a few feet above the ground, a small crow was clinging, swaying up and down like a bobolink on a cardinal flower, balancing himself gracefully by spreading his wings, and every few minutes giving the strange cracking sound, accompanied by a flirt of his wings and tail as the branch swayed upward. At every repet.i.tion the crows _hawed_ in applause. I watched them fully ten minutes before they saw me and flew away.

Several times since, I have been attracted by unusual sounds, and have surprised a flock of crows which were evidently watching a performance by one of their number. Once it was a deep musical whistle, much like the _too-loo-loo_ of the blue jay (who is the crow's cousin, for all his bright colors), but deeper and fuller, and without the trill that always marks the blue jay's whistle. Once, in some big woods in Maine, it was a hoa.r.s.e bark, utterly unlike a bird call, which made me slip heavy sh.e.l.ls into my gun and creep forward, expecting some strange beast that I had never before met.

The same love of variety and excitement leads the crow to investigate any unusual sight or sound that catches his attention. Hide anywhere in the woods, and make any queer sound you will--play a jews'-harp, or pull a devil's fiddle, or just call softly--and first comes a blue jay, all agog to find out all about it. Next a red squirrel steals down and barks just over your head, to make you start if possible.

Then, if your eyes are sharp, you will see a crow gliding from thicket to thicket, keeping out of sight as much as possible, but drawing nearer and nearer to investigate the unusual sound. And if he is suspicious or unsatisfied, he will hide and wait patiently for you to come out and show yourself.

Not only is he curious about you, and watches you as you go about the woods, but he watches his neighbors as well. When a fox is started you can often trace his course, far ahead of your dogs, by the crows circling over him and calling _rascal, rascal_, whenever he shows himself. He watches the ducks and plover, the deer and bear; he knows where they are, and what they are doing; and he will go far out of his way to warn them, as well as his own kind, at the approach of danger.

When birds nest, or foxes den, or beasts fight in the woods, he is there to see it. When other things fail he will even play jokes, as upon one occasion when I saw a young crow hide in a hole in a pine tree, and for two hours keep a whole flock in a frenzy of excitement by his distressed cawing. He would venture out when they were at a distance, peek all about cautiously to see that no one saw him, then set up a heart-rending appeal, only to dodge back out of sight when the flock came rushing in with a clamor that was deafening.

Only one of two explanations can account for his action in this case; either he was a young crow who did not appreciate the gravity of crying _wolf, wolf!_ when there was no wolf, or else it was a plain game of hide-and-seek. When the crows at length found him they chased him out of sight, either to chastise him, or, as I am inclined now to think, each one sought to catch him for the privilege of being the next to hide.

In fact, whenever one hears a flock of crows _hawing_ away in the woods, he may be sure that some excitement is afoot that will well repay his time and patience to investigate.

Since the above article was written, some more curious crow-ways have come to light. Here is one which seems to throw light on the question of their playing games. I found it out one afternoon last September, when a vigorous cawing over in the woods induced me to leave the orchard, where I was picking apples, for the more exciting occupation of spying on my dark neighbors.

The clamor came from an old deserted pasture, bounded on three sides by pine woods, and on the fourth by half wild fields that straggled away to the dusty road beyond. Once, long ago, there was a farm there; but even the cellars have disappeared, and the crows no longer fear the place.

It was an easy task to creep un.o.bserved through the nearest pine grove, and gain a safe hiding place under some junipers on the edge of the old pasture. The cawing meanwhile was intermittent; at times it broke out in a perfect babel, as if every crow were doing his best to outcaw all the others; again there was silence save for an occasional short note, the _all's well_ of the sentinel on guard. The crows are never so busy or so interested that they neglect this precaution.

When I reached the junipers, the crows--half a hundred of them--were ranged in the pine tops along one edge of the open. They were quiet enough, save for an occasional scramble for position, evidently waiting for something to happen. Down on my right, on the fourth or open side of the pasture, a solitary old crow was perched in the top of a tall hickory. I might have taken him for a sentry but for a bright object which he held in his beak. It was too far to make out what the object was; but whenever he turned his head it flashed in the sunlight like a bit of gla.s.s.

As I watched him curiously he launched himself into the air and came speeding down the center of the field, making for the pines at the opposite end. Instantly every crow was on the wing; they shot out from both sides, many that I had not seen before, all cawing like mad. They rushed upon the old fellow from the hickory, and for a few moments it was impossible to make out anything except a whirling, diving rush of black wings. The din meanwhile was deafening.

Something bright dropped from the excited flock, and a single crow swooped after it; but I was too much interested in the rush to note what became of him. The clamor ceased abruptly. The crows, after a short practice in rising, falling, and wheeling to command, settled in the pines on both sides of the field, where they had been before. And there in the hickory was another crow with the same bright, flashing thing in his beak.

There was a long wait this time, as if for a breathing spell. Then the solitary crow came skimming down the field again without warning. The flock surrounded him on the moment, with the evident intention of hindering his flight as much as possible. They flapped their wings in his face; they zig-zagged in front of him; they attempted to light on his back. In vain he twisted and dodged and dropped like a stone.

Wherever he turned he found fluttering wings to oppose his flight. The first object of the game was apparent: he was trying to reach the goal of pines opposite the hickory, and the others were trying to prevent it. Again and again the leader was lost to sight; but whenever the sunlight flashed from the bright thing he carried, he was certain to be found in the very midst of a clamoring crowd. Then the second object was clear: the crows were trying to confuse him and make him drop the talisman.

[Ill.u.s.tration]

They circled rapidly down the field and back again, near the watcher.

Suddenly the bright thing dropped, reaching the ground before it was discovered. Three or four crows swooped upon it, and a lively scrimmage began for its possession. In the midst of the struggle a small crow shot under the contestants, and before they knew what was up he was scurrying away to the hickory with the coveted trinket held as high as he could carry it, as if in triumph at his sharp trick.
