CHAPTER III.
METHODS OF DEFENCE.
FLIGHT — FEINT — RESISTANCE IN COMMON BY SOCIAL ANIMALS — SENTINELS.
Studying the animal kingdom in the manner here adopted, that is to say by passing in review the various manifestations of zoological life, we are necessarily led to find certain industries which are opposed to others. We have seen the various methods of hunting; but attack calls forth defence. In the struggle for life we find the action of beings on other beings, and the re-action of these latter; the final result is the expression of the difference between the two according as one or the other is stronger.
Flight. — Just as the most rudimentary method of attack is simple pursuit, so the most simple and natural method of defence is flight; but if very fleet animals like hares, gazelles, and deer can escape by simply exerting their maximum rapidity, it is not always thus, and certain species exercise in flight perfected methods appropriate to circumstances, and so raise this method of defence to an art.
Of all animals the Ape most skilfully directs his flight. There is no question that in his intelligence we may find every rudiment of our own; but of all his qualities none more nearly approximates him to us than his courage. There are no animals, not even the great beasts of prey, who are so brave as Man and the Ape, and who are capable of so much presence of mind. It is perhaps this bravery which, joined to his sociability, has most contributed to assure the supremacy of the one. As to the other, the road has been barred to him by his better-endowed cousin; he is disappearing before Man, and not before nature or other animals. In thinly-inhabited regions he is still the king. It is generally considered that the Lion is the incarnation of courage, but he is the strongest and the best armed; there is none before whom he need tremble. In captivity he allows himself to be struck by the tamer, which the most miserable ape would never suffer. The Lion will struggle with extreme energy without calculating the difference of strength between his opponent and himself, and will resist as long as he is able to move. The Ape directs all his courage and presence of mind to order his flight when he has recognised a danger that is insurmountable. He does not act like those infatuated beasts who lose their head and rush away trembling, in their precipitation paralysing a great part of their resources. A band of apes in flight utilises all obstacles that can be interposed between themselves and the pursuer; they retire without excessive haste and take advantage of the first shelter met with; a female never abandons her young, and if a young one remains behind, and is in danger of being taken, the old males of the troop go back boldly to save it at the peril of their lives. In this connection many heroic facts have been narrated. This animal has too frequently been judged by comparison with ourselves; he has been regarded as a human caricature and covered with ridicule. We obtain a very much higher idea of him if we compare him with other animals. Always and everywhere there has been a prejudiced insistence on his defects; we perceive them so easily because they are an exaggeration of our own; but he also possesses qualities of the first order.
As an example of flight arranged with intelligence, we have already seen how the Formica fusca profits by the difficulty experienced by the Polyergus in climbing. It hastily gains the summit of a blade of grass, to place there in safety the larvæ which the others wish to carry away. The ruses adopted in flight are as varied as those of attack. Every animal tries to profit as much as possible by all his resources.
Larks, a feeble race of birds, rise higher in the air than any rapacious bird, and this is often a cause of safety. Their greatest enemy is the Hobby (Hypotriorchis sublutes). They fear him greatly, so that as soon as one appears singing ceases, and each suddenly closes his wings, falls to the earth and hides against the soil. But some have mounted so high to pour out their clear song that they cannot hope to reach the earth before being seized. Then, knowing that the bird of prey is to be feared when he occupies a more elevated position from which he can throw himself on them, they endeavour to remain always above him. They mount higher and higher. The enemy seeks to pass them, but they mount still, until at last the Hobby, heavier, and little accustomed to this rarefied air, grows tired and gives up the pursuit.[37]
