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.
