The PIED OYSTER-CATCHER, or SEA PIE (_Hæmatopus ostralegus_), possesses a compact body, large head, long straight beak, which is much compressed and of conical form; moderately high, powerful feet, furnished with short broad toes connected by a skin; medium-sized and pointed wings, in which the first quill is the longest; and a short straight tail, composed of twelve feathers. The plumage on the upper portions of the body is of a glossy black; the neck, crop, and rump, a patch under the eye and the belly are white; the primary quills and tail-feathers black, with white roots. The eyes are bright blood-red, edged with orange. The broad rings that surrounds the eyes and the beak are vermilion, the latter tipped with a lighter shade; the feet are dark flesh-red. The length of the male is sixteen inches; its breadth across the wings thirty-one inches and a half; the wing measures nine inches and a half, and the tail fully four inches. The female is smaller than her mate, and has less black upon her breast. During the winter this species has a crescent-shaped white patch upon the throat. The Pied Oyster-catchers are met with along almost the entire coast of the Old and New Worlds (being especially numerous on the more rocky portions). They are also found in Greenland and on the islands of the Northern and Arctic Oceans. During the winter they appear in Southern Europe, but are by no means common. The migrations of these birds vary considerably with the climate of their native haunts; such as inhabit shores warmed by the Gulf Stream remaining in the same localities from one year to another; whilst in those latitudes where the seas are covered with ice during the cold season, they are compelled to go south in order to obtain the requisite supply of food. During the course of these enforced wanderings the mainland is rarely traversed, the fugitive keeping as near as possible to the shore, or, when necessary, crossing even large tracts of water without any inconvenience. Occupants of the shores of the eastern and northern seas seek their winter quarters principally in France and the north of Spain, whilst those occupying the coast of China appear regularly in Southern India. In Great Britain the Pied Oyster-catchers are permanent residents, and never extend their flight to any great distance, but after the breeding season assemble in flocks, and in winter betake themselves to estuaries and promontories. In April these flocks disperse in pairs, and rove about the sandy beach in small parties. While searching for food they usually keep apart from other birds, but are occasionally seen in company with the Curlew, Turnstone, and Redshank. At high-water they retire to rocky headlands or similar places of safety, where they remain until the turn of the tide has left their hunting-grounds again exposed. While reposing, according to Macgillivray, the Sea Pies stand with their legs quite straight, or on one leg only, the other being drawn up; the
