I wish those who see cougars kill game, or who come on game that they have killed, would study and record the exact method employed in killing. Mr. Hornaday sent me a photograph of a cougar killing a goat, which he had seized high up on the back of the neck in his jaws, not using his claws at all. I once found where one had killed a big buck by seizing him by the throat; the claws also having evidently been used to hold the buck in the struggle. Another time I found a colt which had been killed by a bite in the neck; and yet another time a young doe which had been killed by a bite in the head. In most cases where I came across the carcasses of deer which had been killed by cougars they had been partially eaten, and it was not possible to find out exactly how they had been slain. In one instance at least the neck had been broken, evidently in the struggle; but I could not tell whether this had been done designedly, by the use of the forepaws. Twice hunters I have known saw cougars seize mountain sheep, in each case by the throat. The information furnished me inclines me to believe that most game is killed by cougars in this fashion. Most of the carcasses of elk which had been killed by cougars that I have examined showed fang marks round the throat and neck; but one certainly did not, though it is possible in this case that the elk died in some other way, and that the cougar had merely been feeding on its dead body. But I have read of cases in which elk and large deer were slain where the carcasses were said to have shown wounds only on the flanks, and where the writers believed—with how much justification I cannot say—that the wounds had been inflicted by the claws. I should be surprised to find that such was the ordinary method with cougars of killing game of any kind; but it is perhaps unsafe to deny the possibility of such an occurrence without more information than is at present available; especially in view of the experience of Brutus Jackson, which I give above. In a letter to Mr. Hornaday a New Mexican hunter, Mr. J. W. Carter, of Truchas, states that cougars rip with their claws in killing game, and that, whether the quarry is a horse, deer, or calf, the cougar begins to eat at the neck. When at bay a cougar kills dogs by biting them, usually in the head; the claws are used merely to scratch or rip, or to drag the dog within reach of the jaws, and to hold it for the fatal bite. Miss Velvin’s studies of dangerous wild beasts in captivity show that the cougar is ordinarily more playful and less wantonly ferocious than the big spotted cats; but that there is a wide individual variation among cougars, a few being treacherous, bad-tempered and dangerous. Mr. Bostock, the animal trainer, states that the cougar is as a rule rather stupid and far less courageous or dangerous than the other big cats, the proportion of vicious individuals being very small. He regards bears as being very dangerous.
