For a long time this bird was almost unknown; and though specimens of it appear to have been examined even by scientific men, its identity as a distinct species remained hidden until the year 1814. In February of that year Mr. Audubon, while voyaging up the Mississippi, noticed here and there a solitary bird, soaring above the rocky cliffs, entirely different, as it appeared to him, from any species with which he was acquainted. After much search he discovered an eyry on the high cliffs of Green River, in Kentucky, and was enabled to make such observations as convinced him that this was a new, and hitherto unknown, species of Eagle. From its noble bearing and majestic size, he named it the Bird of Washington, a title by which it is now generally recognized. Some, however, confound it with the White-tailed Eagle, and others affirm that it is but a full grown Sea Eagle. With better reason it is supposed to be either identical with the great European Sea Eagle of Brisson, or but a variety of that bird. Audubon considers the species as rare. His principal residence is among the rocky shores of the Mississippi, the Missouri, and the great northern lakes—in those gloomy solitudes rarely disturbed by the step of man. Winter drives it from these favorite haunts nearer to the abode of civilization; and in a severe season the Washington Eagle has been seen in the vicinity of Concord and Boston. His principal food is fish; but instead of obtaining it in the same piratical manner as is common with the Bald Eagle, he descends, like the Osprey, into the same element with his prey. The circles which he describes in flying are wider than those of the White-headed Eagle, and when about to dive for prey, he sweeps downward in spiral rings, as though endeavoring to prevent the fish’s escape. When within the distance of a few yards, he darts forcibly down, and rarely fails to secure his object. He is also remarkable for flying near the surface of the water, especially when retiring with his prize; and when near the shore he may often be recognized by the same peculiarity. The Washington Eagle is capable of being domesticated, and is then gentle and docile. The quantity of food necessary to sustain him, either in captivity or among his native wilds, is very great; and it would appear that they are capable, more than most birds of prey, of generating fat. Audubon’s specimen was three feet six inches in length, and weighed fourteen and a half pounds. Others have been weighed, much heavier. It should be mentioned as a curious fact, that repeated attempts by Dr. Haywood, of Boston, to poison one of these birds with corrosive sublimate were entirely unsuccessful, although doses of two drams were given to it at a time.
