A frog is like an ostrich. When he sees nothing, because his head is hidden, he thinks nothing can see him. At the sudden alarm Mother Quoskh would stretch her neck, watching the frog’s flight; then turn her head so that her long bill pointed directly at the bump on the muddy bottom, which marked the hiding place of Chigwooltz, and croak softly as a signal. At the sound one of the young herons would hurry forward eagerly; follow his mother’s bill, which remained motionless, pointing all the while; twist his head till he saw the frog’s back in the mud, and then lunge at it like lightning. Generally he got his frog, and through your glass you would see the unfortunate creature wriggling and kicking his way into Quoskh’s yellow beak. If the lunge missed, the mother’s keen eye followed the frog’s frantic rush through the mud, with a longer trail this time behind him, till he hid again; whereupon she croaked the same youngster up for another try, and then the whole family moved jerkily along, like a row of boys on stilts, to the next clump of lily pads.
As the young grew older and stronger on their legs, I noticed the rudiments, at least, of a curious habit of dancing, which seems to belong to most of our long-legged wading birds. Sometimes, sitting quietly in my canoe, I would see the young birds sail down in a long slant to the shore. Immediately on alighting, before they gave any thought to frogs or fish or carnal appetite, they would hop up and down, balancing, swaying, spreading their wings, and hopping again round about each other, as if bewitched. A few moments of this crazy performance, and then they would stalk sedately along the shore, as if ashamed of their ungainly levity; but at any moment the ecstasy might seize them and they would hop again, as if they simply could not help it. This occurred generally towards evening, when the birds had fed full and were ready for play or for stretching their broad wings in preparation for the long autumn flight.
Watching them, one evening, I remembered suddenly a curious scene that I had stumbled upon when a boy. I had seen a great blue heron sail croaking, croaking, into an arm of the big pond where I was catching bullpouts, and crept down through dense woods to find out what he was croaking about. Instead of one, I found eight or ten of the great birds on an open shore, hopping ecstatically through some kind of a crazy dance. A twig snapped as I crept nearer, and they scattered in instant flight. It was September, and the instinct to flock and to migrate was at work among them. When they came together for the first time some dim, old remembrance of generations long gone by—the shreds of an ancient instinct, whose meaning we can only guess at—had set them to dancing wildly;
though I doubted at the time whether they understood much what they were doing.
Perhaps I was wrong in this. Watching the young birds at their ungainly hopping, the impulse to dance seemed uncontrollable; yet they were immensely dignified about it at times; and again they appeared to get some fun out of it—as much, perhaps, as we do out of some of our peculiar dances, of which a visiting Chinaman once asked innocently: "Why don’t you let your servants do it for you?"
I have seen little green herons do the same thing in the woods at mating time; and once, in the Zoölogical Gardens at Antwerp, I saw a magnificent hopping performance by some giant cranes from Africa. Our own sand-hill and whooping cranes are notorious dancers; and undoubtedly it is more or less instinctive with all the tribes of the cranes and herons, from the least to the greatest. But what the instinct means—unless, like our own dancing, it is a pure bit of pleasure-making, as crows play games and loons swim races—nobody can tell.
Before the young were fully grown, and while yet they were following the mother to learn the ways of frogging and fishing, a startling thing occurred which made me ever afterwards look up to Quoskh with honest admiration. I was still-fishing in the middle of the big lake, one late afternoon, when Quoskh and her little ones sailed over the trees from the beaver pond and lit on a grassy shore. A shallow little brook stole into the lake there, and Mother Quoskh left her young to frog for themselves, while she went fishing up the brook under the alders. I was watching the young herons through my glass when I saw a sudden rush in the tall grass near them. All three humped themselves, heron fashion, on the instant. Two got away safely; the other had barely spread his wings when a black animal leaped out of the grass for his neck and pulled him down, flapping and croaking desperately.
I pulled up my killick on the instant and paddled over to see what was going on, and what the creature was that had leaped out of the grass. Before my paddle had swung a dozen strokes I saw the alders by the brook open swiftly, and Mother Quoskh sailed out and drove like an arrow straight at the struggling wing tips, which still flapped spasmodically above the grass. Almost before her feet had dropped to a solid landing she struck two fierce, blinding, downward blows of her great wings. Her neck curved back and shot straight out, driving the keen six-inch bill before it, quicker than ever a Roman arm drove its javelin. Above the lap-lap of my canoe I heard a savage cry of pain; the same black animal leaped up out of the tangled grass, snapping for the neck; and a desperate battle began, with short gasping croaks and snarls that made caution unnecessary as I sped over to see who the robber was, and how Quoskh was faring in the good fight.
