Anyone who has visited Switzerland has often seen these powerful Birds swaying majestically over the highest point of the Alps. With widespread wings they glide along with easy motion. The sharp eye searches the earth anxiously and discerns the smallest prey from the greatest height. The Bird descends with slow circling movements and presently drawing his wings with loud, rustling noise, he darts to the earth like an arrow. He buries his outstretched fangs into the body of his prey and crushes it sooner or later, according to its size and power of resistance, without the use of his bill. After killing his prize, the Eagle spreads himself out to his full size and gives vent to a triumphant shriek of conscious victory. The powerful bill then begins the work of annihilation.
He steals smaller and larger animals—Rabbits, Lambs, Kids and Foxes. Nordmann relates that Stone Eagles have even been known to pounce upon heavy Swine. Neither are small Children safe from him. Among Birds, his prey is the Crane, Stork, Duck, Goose, etc., or any large and clumsy Bird. He does not attack swift Birds.
In the spring they hatch their eggs in a lonely, quiet cliff on the mountains, locating the nest in a strong tree. No other interloper is tolerated in the same district. Should any such appear, the male Stone Eagle advances with loud, angry shrieks. The intruder pauses, startled for the moment. He does not feel safe in the strange district and hesitates for a moment as to whether to undertake the combat with the rightful owner of the district. Soon, however, his boldness overweighs his better judgment and the powerful Birds circle about each other seeking to attack a weak spot. They circle nearer and presently with a bold plunge one swoops down upon his opponent. Each clutches the other with powerful fangs, making the blood flow and amid the rushing noise of the flapping wings, furious blows are struck, causing the feathers to fly in every direction. The combatants gradually sink lower and soon touch the earth upon which they roll about. Presently the intruder endeavors to free himself and, bleeding from many wounds, hastens away. The victor pursues him for a short distance and finally returns to his mate, who, having been an interested witness of the combat from the distance, welcomes him with joyful clamor.
The Stone Eagle lays from two to four eggs, about the size of a Peacock’s, of a greenish white color with brown spots. During the time their young remain in the nest the parents’ search for prey is continuous. In one of the nests, Hunter Regg found part of a Fox, a Prairie Dog and remains of not less than five Rabbits of the Alps.
THE SEA EAGLE.
Falcons Fighting.
The common name of the Sea Eagle—Pygargus—is derived from the Greek word which means “white tail.” These Birds feed on Fish and aquatic Birds. They are found along the shores of Europe, Northern Siberia, Asia Minor and Egypt. A powerful, bold and dangerous Bird of Prey, with a covering of slate colored and golden brown feathers with light and dark streaks and bands. Like the Stone Eagle, he pursues every wild animal he can overpower and besides this, he makes good use of his unfeathered talons to the terror of the watery inhabitants, in catching Fish with ease. The Porcupine’s prickly coat is no protection against him, nor the Fox’s sharp teeth. Neither the precaution of the Wild Goose, nor the readiness of the Diving Bird in disappearing under the waves, nor the guard of the faithful Dog and Shepherd over the Lamb. Neither the Fish’s cool element. All are the prey of the bold robber. He attacks Children, and, under favorable conditions, even grown persons. His principal nourishment is Fish and for this reason his aerie is generally near the seacoast or large inland streams. He does not at all despise carrion and during the winter regularly haunts fishing places and the regions of mankind, such as flaying places, slaughter-houses, etc., wherever there is a possibility of his obtaining booty. In Northern Russia and Siberia, in the winter, when every river and pond is frozen over, the Sea Eagle is obliged to exist entirely on land animals, and overcome by hunger boldly snatches a Fox from the horde (see illustration), soars away with and kills him; heedless of his struggles and attempt to free himself, by attacking with his sharp teeth, the fangs and bill grasping him.
