This bird is found throughout the entire continent of Europe, the greater part of Asia, and upon the rivers of Northern and Western Africa. Many naturalists are of opinion that the American Ospreys should be regarded as the same species, so very slightly do they differ from their European representatives, either in their appearance or manner of life. The River Eagle lives almost exclusively upon fish, and passes its life in such places as afford a plentiful supply; it only visits northern regions during the summer months, remaining throughout the rest of the year in warmer latitudes. During the course of its migrations, every piece of water over which it passes is subjected to close inspection, and even the finny inhabitants of the humblest pond are not safe from this most destructive and voracious marauder. Its eyrie is usually constructed upon a high tree, and formed of moss and twigs; the eggs, two or three in number, are greyish white, marked with pale yellowish red spots. Owing to the great strength of its wings, this bird is capable of flying to a very considerable distance from its roosting-place, to which, however, it always returns for rest or shelter. As soon as the mist has cleared away from the surface of the water, the business of the day commences, and about noon the Osprey may be seen careering through the air, preparatory to descending by a series of graceful evolutions upon the river or lake, over which it has hitherto sailed at a considerable altitude. At the first indication of a fish being about to rise, the observant bird arrests its progress, hovers for a moment above the spot, and then swoops down with great velocity upon its prey. All attempts to elude the fierce destroyer are useless, for even should the Osprey be completely submerged during the struggle, it rises again with ease, bearing its prize safely grasped by the back, shakes the water from its wings, and flies away with its victim to a neighbouring tree, or, if too heavy, drags it to the bank there to be devoured. The only exception to this mode of fishing is when the Osprey perceives an eel in the vicinity of the water, this it pounces upon, and transfixes with its "iron talons," and then, after tearing it to pieces, devours some portions of the body, entirely rejecting the entrails. Next to the Otter, this Eagle may be considered as the most destructive of all the many enemies to whose attacks well-stocked ponds and rivers are incessantly exposed, and for this reason it is regarded with great hostility by all cultivators of fish. In North America alone it is treated with favour, being supposed, by a popular superstition, to bring luck to the district in which it builds its nest. With all varieties of swimming birds the Osprey lives upon the most amicable terms, but Crows, Swallows, and Wagtails pursue and harass it so perseveringly that it will often throw down its hardly-earned booty in order to escape from their unrelenting persecution.
