The habits of the leopard are invariably the same, it prowls stealthily about sunset and throughout the night in search of prey. It seizes by the throat and clings with tenacious claws to the animal's neck, until it succeeds either in breaking the spine, or in strangling its victim, should the bone resist its strength. When the animal is dead, the leopard never attacks the hind-quarters first, according to the custom of the tiger, but it tears the belly open, and drags out all the viscera, making its first meal upon the heart, lungs, liver, and the inside generally. It then retreats to some neighbouring hiding-place, and, if undisturbed, it will return to its prey a little after sundown on the following day. It is far more difficult to circumvent a leopard than a tiger; the latter seldom or never looks upwards to the trees, therefore it does not perceive the hidden danger when the hunter is watching from his elevated post; but the leopard approaches its kill in the most wary and cautious manner, crouching occasionally, and examining every yard of the ground before it, at the same time scanning the overhanging boughs, which it so frequently seeks as a place of refuge. Upon many occasions, when the disappointed watcher imagines that the leopard has forsaken its kill, and that his patience will be unrewarded, the animal may be closely scanning him from the dense bush, under cover of which it was noiselessly approaching. In such a case the leopard would retreat as silently as it had advanced, and the watcher would return home from a fruitless vigil, under the impression that the leopard had never been within a mile of his position. One of the cleverest birds in creation is the ordinary crow of all tropical countries, which lives well by the exercise of its wits; nothing escapes the observation of this bird, and it is the first to discover the body of any animal that may have been killed. Should one or more of these birds be perched in the trees after sunset, near the carcase of an animal, and should it utter a "caw," when at that late hour it should have gone to roost, you may be assured that it has espied an approaching leopard, although it may be invisible to your own sight. The watcher should be careful not to move, but to redouble his vigilance in keeping a bright look-out, as the leopard will be equally upon its guard should it hear the cry of the warning crow.
