Though I was near enough to see him clearly without, my field glasses, I could not even then, nor at any other time when I have watched grouse drumming, determine just how the call is given. After a little while the excitement of a suspected rival's presence wore away, and he grew exultant, thinking that he had driven the rascal out of his woods. He strutted back and forth on the log, trailing his wings, spreading wide his beautiful tail, lifting his crest and his resplendent ruff. Suddenly he would draw himself up; there would be a flash of his wings up and down that no eye could follow, and I would hear a single throb of his drum. Anotherflash and another throb; then faster and faster, till he seemed to have two or three pairs of wings, whirring and running together like the spokes of a swift-moving wheel, and the drumbeats rolled together into a long call and died away in the woods.
Generally he stood up on his toes, as a rooster does when he flaps his wings before crowing; rarely he crouched down close to the log; but I doubt if he beat the wood with his wings, as is often claimed. Yet the two logs were different; one was dry and hard, the other mouldy and moss- grown; and the drumcalls were as different as the two logs. After a time I could tell by the sound which log he was using at the first beat of his wings; but that, I think, was a matter of resonance, a kind of sounding- board effect, and not because the two sounded differently as he beat them. The call is undoubtedly made either by striking the wings together over his back or, as I am inclined to believe, by striking them on the down beat against his own sides.
Once I heard a wounded bird give three or four beats of his drum-call, and when I went into the grapevine thicket, where he had fallen, I found him lying flat on his back, beating his sides with his wings.
Whenever he drums he first struts, because he knows not how many pairs of bright eyes are watching him shyly out of the coverts. Once, when I had watched him strut and drum a few times, the leaves rustled, and two hen grouse emerged from opposite sides into the little opening where his log was. Then he strutted with greater vanity than before, while the two hen grouse went gliding about the place, searching for seeds apparently, but in reality watching his every movement out of their eye corners, and admiring him to his heart's content.
In winter I used to follow his trail through the snow to find what he had been doing, and what he had found to eat in nature's scarce time. His worst enemies, the man and his dog, were no longer to be feared, being restrained by law, and he roamed the woods with greater freedom than ever. He seemed to know that he was safe at this time, and more than once I trailed him up to his hiding and saw him whirr away through the open woods, sending down a shower of snow behind him, as if in that curious way to hide his line of flight from my eyes.
There were other enemies, however, whom no law restrained, save the universal wood-laws of fear and hunger. Often I found the trail of a fox crossing his in the snow; and once I followed a double trail, fox over grouse, for nearly half a mile. The fox had struck the trail late the previous afternoon, and followed it to a bullbrier thicket, in the midst of which was a great cedar in which the old beech partridge roosted. The fox went twice around the tree, halting and looking up, then went straight away to the swamp, as if he knew it was of no use to watch longer.
Rarely, when the snow was deep, I found the place where he, or some other grouse, went to sleep on the ground. He would plunge down from a tree into the soft snow, driving into it headfirst for three or four feet, then turn around and settle down in his white warm chamber for the night. I would find the small hole where he plunged in at evening, and near it the great hole where he burst out when the light waked him. Taking my direction from his wing prints in the snow, I would follow to find where he lit, and then trace him on his morning wanderings.
