The jaguar is perhaps even a better climber than the leopard, and seems far more at its ease among the branches than on the ground. Indeed, there are some parts of the great swampy forests of Brazil in which the animal is said never to descend to the ground at all, but to spend its whole life in the trees which stand so close side by side that it can easily spring from one to another. You wonder, perhaps, what it feeds upon. Why, upon monkeys, and very active indeed it has to be if it wishes to catch them. But then, when a band of monkeys discover a jaguar, they are never able to resist the temptation of getting as close to him as they dare, and chattering and screaming as loudly as they can, just to annoy him. Isn't that exactly like monkeys? But sometimes they venture a little _too_ close, and then with a sudden spring he seizes the nearest of his impudent tormentors and carries it shrieking away. Birds, too, are often caught by the jaguar, who pounces upon them as they are roosting upon a branch. But he is not at all particular as to what he eats, and sometimes he will leave the trees altogether, and go hunting in the reed-beds by the riverside for capybaras, which we will describe farther on. He is very fond of these animals, for they are so slow in their movements that they cannot run away, so badly provided with natural weapons that they cannot fight, and so fat and delicate that they afford most excellent eating. Then, just for a change, perhaps, he will stroll down to the sea-shore, and look for a good big turtle. When he sees one--which is generally a female on her way back to the water after laying her eggs in the sand--he seizes it suddenly with his fore paws, and turns it over on its back, so that it cannot possibly escape. Then, perhaps, if he is not very hungry, he leaves it for a little while. But soon he returns, and manages to scoop out all the flesh of the animal from between the shells by means of his long hooked talons, thrusting in his paw over and over again, till scarcely the smallest particle is left remaining. Very likely, too, he will find the spot where the turtle had laid her eggs, dig them up, and devour them as well. Sometimes he will crouch on the bank of a stream, quite close to the water, and hook out the fish that pass by with his claws. And when he is very hungry indeed he will eat lizards and even insects. Like the ounce, however, the jaguar seldom or never ventures to attack a human being, although he will fight savagely if he is driven to bay. But he will often spring upon horses and cattle, and in such cases he nearly always kills them by seizing their heads between his front paws, and giving a sudden wrench sideways and upward so as to break their necks. Like most of the cats, the jaguar has a fondness for scratching the trunks of trees, and sometimes a tree may be found with gashes in its bark an inch deep and more than a yard long.
