Upon the coast of Cape May and Egg Harbour this species is known by the name of the "Horsefoot Snipe," from the fact that it subsists during a portion of the summer almost entirely on the spawn and eggs of the great "king crab," called by the common people the "horsefoot." This spawn may often be seen by bushels in the hollows and eddies on the coast.
During the breeding season these birds retire to high northern latitudes, so that their mode of nidification was long a mystery, until Mr. Hewitson, who made diligent search for the Turnstone's nest on the coast of Norway, was at last successful. "We had," he writes, "visited numerous islands with little encouragement, and were about to land upon a flat rock, bare, except where here and there grew tufts of grass or stunted juniper clinging to its surface, when our attention was attracted by the singular cry of a Turnstone, which in its eager watch had seen our approach and perched itself upon an eminence of the rock, assuring us by its querulous oft-repeated note and anxious motions that its nest was there. We remained in the boat a short time, until we had watched it behind a tuft of grass, near which, after a minute search, we succeeded in finding the nest, in a situation in which I should never have suspected to meet with a bird of this sort breeding; it was placed against the ledge of the rock, and consisted of nothing more than the drooping leaves of the juniper-bush, under a creeping branch of which, the eggs, four in number, were snugly concealed and admirably sheltered from the many storms by which these bleak and exposed rocks are visited, allowing just sufficient room for the bird to cover them. We afterwards found more nests with little difficulty. All the nests contained four eggs each. The time of breeding is about the middle of June. The eggs measure one inch and two lines in breadth, and are of an olive-green colour, spotted and streaked with ash-blue and two shades of reddish brown."
The parents are much attached to their offspring. The habits of the latter resemble those of young Plovers. Audubon mentions an instance in which one of these birds was reared by a lady, who fed it on boiled rice and bread soaked in milk.[Pg 27]
THE PIED OYSTER-CATCHER, OR SEA PIE.
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 body is held in a horizontal position; the neck retracted; the head either directed forward or with the bill buried among the feathers of the back. In this attitude they present a very curious appearance when seen in a high wind, as each bird directs its breast towards the quarter from which it blows. On a sandy beach they often follow each other in long lines, or crouch to the ground. Their flight is strong and steady, performed by regular beats of the extended wings, with the neck drawn in, and the feet directed backwards. When going to sleep they rest on one leg only. Over the surface of the sandy shore they run with great rapidity, and wade with ease in muddy places, their short, flat-soled feet being well adapted for that purpose. During the period of incubation the Sea Pies utter a great variety of pleasing notes, whilst at other times their cry is not particularly agreeable. Of all the many feathered occupants of our shores, these birds are by far the most restless and pugnacious, though apparently without malice. Towards all their larger companions they exhibit an incessant desire to resent intrusion, and at once dart upon a bird of prey with loud cries, and drive the unwelcome visitor away from the spot. Should no foreign foe appear, and thus[Pg 28] afford them an opportunity for venting their exuberant spirits, the males will harry and annoy each other until their fury rising, the strife that apparently began in sport terminates in a real battle, during which the antagonists strike each other most mercilessly with their wings and beak. Towards men they exhibit extreme shyness, and, except during the breeding season, scarcely permit his approach. In this particular, however, they show much intelligence, and readily distinguish the shepherd or fishermen from their enemy the sportsman. "After the breeding season," says Macgillivray, "the Sea Pies, especially plentiful in the Scottish Isles, form flocks that are frequently very numerous, being composed of from twenty to one hundred individuals or more. At this period they are met with chiefly on the low rocky shores, or at the mouths of rivers, where at low water they obtain their food, which consists of limpets, barnacles, small bivalve shells swallowed entire, young crabs, and other marine animals. Although frequently seen on extensive low sands, they seem rather to betake themselves thither for security than for the purpose of looking for food. On low, pebbly, muddy, or sandy shores they always prefer the edge of the water, in which they wade, although they search the exposed parts. Limpets and barnacles form their chief food; but, although they have been said to eat oysters and large bivalve mollusca, I have not found such animals in their stomach. The bivalve shells found in their gizzard or œsophagus are generally, when of small size, either entire or merely crushed, but when large, are deprived in a greater or less degree of their testaceous envelopes. Along with their food they swallow particles of gravel, frequently of considerable size. I have found some a quarter of an inch in diameter."

[Pg 29]
Bivalve shells, when closed, are usually opened by these birds by striking them at the hinge, while cockles are obtained by holding the shell with the foot and wrenching with the bill as with a crowbar. When the shores are flat and the surface thus remains covered with a shallow stratum of water, after the tide has ebbed, the Oyster-catchers find their prey more readily, as the shells are then partially opened, and they can easily insert their wedge-shaped bill and force them asunder; but where the sand soon dries and there are no rocks from which the limpet can be obtained, they follow the line of the advancing and retreating waves. Such of these birds as are stationary during all seasons commence the business of incubation as early as the middle of April, while such as migrate do not lay until somewhat later in the spring; at this season, after the usual rivalry between the males, the pairs keep apart from each other, but frequently remain in the immediate vicinity of some of their weaker feathered associates, with whom they live in the utmost harmony. The nest of the Sea Pie is a mere hollow in the shore, and is usually situated amongst the tangled weed thrown above high water mark, or on grassy spots in the immediate vicinity of the sea. The eggs, two or three in number, are large and of an oval form with a pale brownish shell, spotted, streaked, and very variously marked with light violet, deep greyish brown and greyish black. The female, who alone broods, does not sit during the noonday hours, and hatches her little family in about three weeks. The young at first conceal themselves if alarmed, but even at a very early period can run, swim, and dive with considerable facility. Whilst in charge of their offspring, the parents exhibit unusual courage and foresight, and should the mother perish, the father at once undertakes all her duties. The flesh of the Sea Pie is unpalatable, but by many the eggs are much esteemed. Gadamer states that a pair of Oyster-catchers reared by him from the nest became so tame that they knew his voice and greeted his appearance with loud cries. These birds were allowed to run freely about the poultry-yard, and rendered excellent service to its more timid occupants by warning the Fowls of the approach of a Hawk, or any other feathered marauder.
