2. When supplied with plenty of food, animals that are naturally afraid of man and fierce appear to submit themselves to him, and to conduct themselves quietly towards each other. The care which is taken of animals in Egypt demonstrates this circumstance; for even the fiercest creatures live together, when they have food enough, and are not in any want; for they become tame from the supply of their wants which they receive, as the crocodiles are tamed by the priests by the care which is bestowed on their food. The same thing may be observed in other countries and in their different parts. 3. The eagle and the dragon are enemies, for the eagle feeds on serpents. The ichneumon and the spider are also enemies, for the ichneumon hunts the spider. Among birds the pœcilis and the lark and the wood-pecker and chloreus are enemies, for they eat each others' eggs. The crow and the owl also are enemies; for at mid-day the crow, taking advantage of the dim sight of the owl, secretly seizes and devours its eggs, and the owl eats those of the crow during the night; and one of these is master during the day, the other during the night. The owl and orchilus are enemies; for the latter eats the eggs of the owl. During the day other birds fly round the owl, which is called "astonishing it," and as they fly round it pluck off its feathers. For this reason fowlers use it in hunting for all kinds of birds. 4. The presbys contends with the weasel and crow, for they eat its eggs and young. The turtle and pyrallis are foes, for their food and mode of life are the same. The celeus and libyus, kite and raven are enemies; for the kite, from the superiority of its claws and flight, can take from the raven anything it may have caught, so that their food is the cause of their enmity also. Those that obtain their food from the sea also are foes, as the brenthus, larus, and harpa. The triorches is a foe to the toad and the serpent; for the triorches eats the others. The turtle and chloreus are foes, for the chloreus kills the turtle, and the crow kills the bird called typanus. The little owl and all other birds with crooked claws eat the calaris, from whence their enmity arises. 5. The gecko and the spider are enemies, for the gecko eats spiders. The pipo is a foe to the heron, for it devours the eggs and young of the heron. Enmity also exists between the ægithus and the ass; for the ass frequents thorny places, that it may scratch its sores, and by this means, and when it brays it overturns the eggs and young of the ægithus, for they fall out of the nest from fear of the noise, and the bird, to revenge this injury, flies upon the ass and inflicts wounds. The wolf is the enemy of the ass, bull, and fox; for being a carnivorous animal, it attacks both oxen, asses, and foxes. The fox and circus are enemies for the same reason; for the circus having crooked claws, and being carnivorous, attacks and inflicts wounds with its claws.
