On one occasion, when I was hidden and watching the carcass of a deer which a lion had killed to see what carnivorous animal might come to the feast, a mountain lion walked quietly and unalertly to it and commenced to eat. After a few minutes the lion suddenly bristled up and spat in the direction from which a grizzly bear presently appeared. With terrible snarling and threatening, the lion held on to the prize until the grizzly was within a few feet. He then leaped toward the grizzly with a snarl, struck at it, and dashed into the woods. The grizzly, without even looking round to see where the lion had gone, began eating.
From many experiences I believe that much of the killing of domestic and wild animals attributed to bears is done by lions. The lion prefers warm blood and fresh meat for each meal, and will kill daily if there is opportunity. I have known bears to follow mountain lions evidently for the purpose of obtaining food. One day I came upon the recently killed carcass of a cow. Only mountain lion tracks led to it and from it. The following night I spent at a near-by ranch house, and the rancher informed me that on the previous day he had discovered a bear eating the carcass of this cow which he accused the bear of killing. The lion is a most capable raider of ranches, and colts, horses, sheep, pigs, and poultry are his prizes.
In northern New Mexico one day I saw a lion bounding across an opening carrying a tame sheep in its mouth. On another occasion I saw a lion carrying off a deer that apparently weighed much more than the lion itself. The lion appeared to have the deer by the shoulder, and it was resting on the lion’s shoulders in such a way that I do not believe it touched the ground.
I suppose when the lion makes a kill in an out-of-the-way place, where he may eat with comparative safety, he does not take the trouble to carry or to drag the victim off. Often, of course, the kill is made for the benefit of the young, and hence must be transported to the den.
It is quite true that he will sometimes wander back to his kill day after day and feast upon it. It is also true, when food is scarce, that lions will eat almost anything, even though they have nothing to do with the killing. They have been trapped at the bait that was out for bears: and so, though a lion prefers blood and warm meat, he will return to his kill to feast, or, if food is scarce, gladly eat whatever he can obtain.
From many observations I judge that after eating he prefers to lie down for a few hours in some sunny or secluded spot, or on a many-branched limb generally well up toward the top of the tree but sometimes not more than ten feet above the earth.
The lion has extreme curiosity. He will follow travellers for hours if there is opportunity to keep out of sight while doing so. Often during long snowshoe trips I have returned over the route first travelled. Lion tracks in the snow showed that I was repeatedly followed for miles. In a number of places, where I had taken a long rest, the lion had crept up close, so that he could easily watch me; and on a few occasions he must have been within a few feet of me.
While walking through a forest in the Medicine Bow Mountains I was startled and knocked down by a glancing blow of a tree limb. This limb had evidently broken off under the weight of a lion. The lion also came tumbling down but caught a claw on a limb and saved himself from striking the earth. Evidently in his curiosity to see me he had leaned out too far on a weak limb. He fled in confusion, perhaps even more frightened than myself.
The mountain lion is not ferocious. Mr. Roosevelt, in summing up its characteristics, concluded that it would be no more dangerous to sleep in woods populated with mountain lions than if they were so many ordinary cats.
In addition to years of camping in the wilds in all sorts of places and under all conditions of weather I have talked with careful frontiersmen, skillful hunters and trappers, and these people uniformly agreed with what I have found to be true—that the instances of mountain lions attacking human beings are exceedingly rare. In each of these cases the peculiar action of the lion and the comparative ineffectiveness of his attacks indicated that he was below normal mentally or nearly exhausted physically.
