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 hoarse bark, utterly unlike a bird call, which made me slip heavy shells 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 unobserved 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 glass.
