Although the eagle is a bird of prey he is used as a national emblem on Persian, Roman and United States coins. Indeed, the eagle is often used for heraldic emblems, standards and various emblematic devices. The eagle is cosmopolitan. The so-called bald-eagle takes three years to complete its plumage; it is called the “black” eagle the first year, the “gray” the second and the “bald” the third year, when the white plumage on neck and head, which gives it the name, is complete. After shedding its feathers in the spring, even the old birds assume the appearance of youth, hence David speaks of the “youth which is renewed like the eagle’s.” An unusual fact in reference to this bird is that the female is said to be larger and braver than the male. A story is told of a pair of eagles in the New York Zoological Park who made a nest in the root of a tree, in a cavity of the ground and lined it with moss. As no eggs were yet ready the birds brought a smooth round stone to the nest on which they sat, male and female, on alternate days. Some such habit as this may account for the idea of the ancients that the eagle carried stones to her nest to facilitate the laying of her eggs. The eagle lives to be very old. It is not especially difficult to tame. A young one caught in the Territory could not be bought. The Indian woman who was taming it refused all offers. She said, “Ah-cha-fa-tona wants young eagle, she not want white man’s money!” “Old Abe”—named for Lincoln—was caught and tamed by soldiers during the civil war. He went through the war delighted with battles. One of his feathers, dropped on the battlefield, was framed and now hangs in Washington. Belle Paxson Drury. [Illustration: BLACK-BELLIED PLOVER. (Charadrius squatarola). ½ Life-size. FROM COL. CHI. ACAD. SCIENCES.] THE BLACK-BELLIED PLOVER. (_Charadrius squatarola_.) The Black-bellied Plover is quite cosmopolitan, though its range is practically confined to the northern hemisphere, passing southward in the winter to the West Indies and northern South America and breeding in the far North. Not only is its range extensive, but also its list of common or local names. Some of the better known of these are Whistling Field Plover, May Cock, Beetle-head, Black-breast and Bottle-head. Its large head has given it the name Bull-head and its large, brilliant and expressive dark colored eyes, which in summer are surrounded by a white ring, have led some of its admirers to call it the Ox-eye.
