EAGLES.
It will be seen, therefore, that when a bird falls asleep upon a branch the legs are not only bent, but are pressed downwards by the weight of the body; so that the claws hold the perch with a firm and involuntary grasp which knows no fatigue, and which remains secure as long as the pressure from above keeps the limbs bent.
To return to the Eagle. When, therefore, the bird desires to drive his talons into the body of his prey, he needs only to sink downwards with his whole weight, and the forcible bending of his legs will contract the talons with irresistible force, without the necessity of any muscular exertion.
Exertion, indeed, is never needlessly used by the Eagle, for it is very chary of putting forth its great muscular powers, and unless roused by the sight of prey, or pressed to fly abroad in search of food, will sit upon a tree or point of rock for hours as motionless as a stuffed figure.
The Golden Eagle is a truly magnificent bird in size and appearance. A full-grown female measures about three feet six inches in length, and the expanse of her wings is nine feet. The male bird is smaller by nearly six inches. The colour of the bird is a rich blackish brown on the greater part of the body, the head and neck being covered with feathers of a golden red, which have earned for the bird its customary name.
The Golden Eagle is observed to frequent certain favourite places, and to breed regularly in the same spot, for a long series of years. The nest is always made upon some high place, generally upon a ledge of rock, and is most roughly constructed of sticks.
In hunting for their prey the Eagle and his mate assist each other. It may be also mentioned here that Eagles keep themselves to a single mate, and live together throughout their lives. Should, however, one of them die or be killed, the survivor does not long remain in a state of loneliness, but vanishes from the spot for a longer or shorter time, and then returns with a new mate.
As rabbits and hares, which form a frequent meal for the Eagle, are usually hidden under bushes and trees during the day, the birds are frequently forced to drive them from their place of concealment; this they have been observed to do in a very clever manner. One of the Eagles conceals itself near the cover, and its companion dashes among the bushes, screaming and making such a disturbance that the terrified inmates rush out in hopes of escape, and are immediately pounced upon by the watchful confederate.
The prey is immediately taken to the nest, and distributed to the young after being torn to pieces by the parent birds.
