The first thing I noticed about the birds—an observation confirmed later on many waters—was that each pair of kingfishers have their own particular pools, over which they exercise unquestioned lordship. There may be a dozen pairs of birds on a single stream; but, so far as I have been able to observe, each family has a certain stretch of water on which no other kingfishers are allowed to fish. They may pass up and down freely, but they never stop at the minnow pools; they are caught watching near them, they are promptly driven out by the rightful owners.
The same thing is true on the lake shores. Whether there is some secret understanding and partition among them, or whether (which is more likely) their right consists in discovery or first arrival, there is no means of knowing.
A curious thing, in this connection, is that while a kingfisher will allow none of his kind to poach on his preserves, he lives at peace with the brood of sheldrakes that occupy the same stretch of river. And the sheldrake eats a dozen fish to his one. The same thing is noticeable among the sheldrakes also, namely, that each pair, or rather each mother and her brood, have their own piece of lake or river on which no others are allowed to fish. The male sheldrakes meanwhile are far away, fishing on their own waters.
I had not half settled this matter of the division of trout streams when another observation came, which was utterly unexpected. Koskomenos, half reptile though he seem, not only recognizes riparian rights, but he is also capable of friendship—and that, too, for a moody prowler of the wilderness whom no one else cares anything about. Here is the proof.
I was out in my canoe alone looking for a loon's nest, one midsummer day, when the fresh trail of a bull caribou drew me to shore. The trail led straight from the water to a broad alder belt, beyond which, on the hillside, I might find the big brute loafing his time away till evening should come, and watch him to see what he would do with himself.
As I turned shoreward a kingfisher sounded his rattle and came darting across the mouth of the bay where Hukweem the loon had hidden her two eggs. I watched him, admiring the rippling sweep of his flight, like the run of a cat's-paw breeze across a sleeping lake, and the clear blue of his crest against the deeper blue of summer sky. Under him his reflection rippled along, like the rush of a gorgeous fish through the glassy water. Opposite my canoe he checked himself, poised an instant in mid-air, watching the minnows that my paddle had disturbed, and dropped bill first—plash! with a silvery tinkle in the sound, as if hidden bells down among the green water weeds had been set to ringing by this sprite of the air. A shower of spray caught the rainbow for a brief instant; the ripples gathered and began to dance over the spot where Koskomenos had gone down, when they were scattered rudely again as he burst out among them with his fish. He swept back to the stub whence he had come, chuckling on the way. There he whacked his fish soundly on the wood, threw his head back, and through the glass I saw the tail of a minnow wriggling slowly down the road that has for him no turning. Then I took up the caribou trail.
I had gone nearly through the alders, following the course of a little brook and stealing along without a sound, when behind me I heard the kingfisher coming above the alders, rattling as if possessed, klrrr, klrrr, klrrr-ik-ik-ik! On the instant there was a heavy plunge and splash just ahead, and the swift rush of some large animal up the hillside. Over me poised the kingfisher, looking down first at me, then ahead at the unknown beast, till the crashing ceased in a faint rustle far away, when he swept back to his fishing-stub, clacking and chuckling immoderately.
I pushed cautiously ahead and came presently to a beautiful pool below a rock, where the hillside shelved gently towards the alders. From the numerous tracks and the look of the place, I knew instantly that I had stumbled upon a bear's bathing pool. The water was still troubled and muddy; huge tracks, all soppy and broken, led up the hillside in big jumps; the moss was torn, the underbrush spattered with shining water drops. "No room for doubt here," I thought; "Mooween was asleep in this pool, and the kingfisher woke him up—but why? and did he do it on purpose?"
I remembered suddenly a record in an old notebook, which reads: "Sugarloaf Lake, 26 July.—Tried to stalk a bear this noon. No luck. He was nosing alongshore and I had a perfect chance; but a kingfisher scared him." I began to wonder how the rattle of a kingfisher, which is one of the commonest sounds on wilderness waters, could scare a bear, who knows all the sounds of the wilderness perfectly. Perhaps Koskomenos has an alarm note and uses it for a friend in time of need, as gulls go out of their way to alarm a flock of sleeping ducks when danger is approaching.
Here was a new trait, a touch of the human in this unknown, clattering suspect of the fishing streams. I resolved to watch him with keener interest.
