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 assembly. 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 snatches 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 hoarse 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 amusement 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 repetition the crows hawed in applause. I watched them fully ten minutes before they saw me and flew away.
