In this class of birds, the beak is generally slender, the legs long and stilt-like. The struthiones live in marshy spots, and on the banks of rivers. They feed upon the reptiles and insects found in water and marshy districts, and upon plants. Most of the wading birds are migratory.

Adjutant (Leptoptilus argala), is a bird, common during summer in India. Generally stork-like in appearance, it stands about five feet high, and measures fourteen or fifteen feet from tip to tip of extended wings. The four-sided pointed bill is very large; the head and neck are almost bare; and a sausage-like pouch, sometimes sixteen inches long, and apparently connected with respiration, hangs down from the base of the neck. While feeding largely on carcases and offal about the towns, it also fishes for living food, and sometimes devours birds and small mammals. The loose under-tail feathers are sometimes used for decorative purposes.

Bittern (Botaurus).—The American species makes a rude nest of sticks, reeds, etc., in its marshy haunts, and lays four or five greenish-brown eggs. The bird is sluggish, and its flight is neither swift nor long sustained. When assailed, it fights desperately with bill and claws; and it is dangerous to approach it incautiously when wounded, as it strikes with its long sharp bill, if possible, at the eye. It is common in many parts of North America, migrating according to the season. The crown of the head is reddish brown, and the colors and markings of the plumage differ [217] considerably from those of the common bittern.

Crane (Grallatores cinerea).—This family of birds differs from herons, storks, etc., in having the hind-toe placed higher on the leg than the front ones, and in certain characters of bill and skull. The members are also less addicted to marshy places, and feed not only on animal, but, to a considerable extent, on vegetable food. The cranes are all large birds, long-legged, long-necked, long-billed, and of powerful wing. Some of them perform great migrations, and fly at a great height in the air. The young cranes are helpless and require to be fed. Only two eggs are laid. The crane, when standing, is about four feet in height; the prevailing color is ash-gray; the head bears bristly feathers, and has a naked crown, reddish in the male; the bill, which is longer than the head, is reddish at the root, dark green at the apex; the feet are blackish; the tail is short and straight. They are very stately birds, though their habit of bowing and dancing is often grotesque. They feed on roots, seeds, etc., as well as on worms, insects, reptiles and even some of the smallest quadrupeds. The flesh is much esteemed.

The Whooping Crane (G. americana) is considerably larger than the common crane, which it otherwise much resembles except in color; its plumage, in its adult state, is pure white, the tips of the wings black. It spends the winter in the southern parts of North America. In summer it migrates far north.

Heron (Ardea) a large bird covered with long, loose down, with large wings, and a hard horny bill longer than the head, compressed from side to side, and united to the skull by firm, broad bones.

In the Heron genus—which includes the species commonly known as Egrets—the plumage is beautiful, but seldom exhibits very gay colors; white, brown, black, and slate, finely blended, generally predominating. The body is small in proportion to the length of the neck and the limbs. Herons are very voracious, feeding mostly on fish and other aquatic animals; but they also often prey on snakes, frogs, rats, and mice, and the young of other birds.

The Common Heron (Ardea cinerea) measures about three feet from the point of the bill to the tip of the tail. It is of a delicate gray color on the upper parts, the quill-feathers are black, the tail of a deep slate color, and the long plume is glossy dark. It generally builds its nest on a high tree; and as many as eighty nests have been counted on a single oak. America has many species of herons, most numerous in its warmer parts.

A common species of the temperate parts is the green heron (A. virescens), whose flesh is much esteemed. Other important species are the Great Blue Heron (A. herodias), the Great White or Florida Heron (A. occidentalis), the Great White Egret (A. egretta), and the Little White Egret (A. candidissima).

The Peacock Heron (A. helias) of South America, a small heron of exquisitely graceful shape and mien, with plumage variegated with colored spots and bars, is a favorite pet bird of the Brazilians.

Ibis (Ibidoideæ).—These birds are related to the spoonbills, and, more remotely, to the storks and herons. The bill is long, slender, curved, thick at the base, the point rather obtuse, the upper mandible deeply grooved throughout its length. The face and generally the greater part of the head, and sometimes even the neck, are destitute of feathers, at least in adult birds. The plumage is mainly white, with black feathers and plumes on the wings. The neck is long. The legs are rather long, naked above the joint, with three partially united toes in front, and one behind; the wings are moderately long; the tail is very short.

The Sacred or Egyptian Ibis, is an African bird, two feet six inches in length, although the body is little larger than that of a common fowl. The ancient Egyptians worshiped it as the emblem of purity, and used to embalm it.

The Glossy Ibis is a smaller species, also African, but migrating northward into continental Europe, and occasionally seen in Britain. It is also a North American bird. Its habits resemble those of the Sacred Ibis. Its color is black, varied with reddish brown, and exhibiting fine purple and green reflections. It has no loose pendent feathers.

The White Ibis, a species with pure white plumage, once abounded on the coasts of Florida, but has been killed off by feather hunters, so that it is rare except in the remote tropics.

The Scarlet Ibis is a tropical American species, remarkable for its brilliant plumage, which is scarlet, with a few patches of glossy black.

The Straw-necked Ibis is a large Australian bird of fine plumage, remarkable for stiff, naked, yellow feather-shafts on the neck and throat.

Plovers.—Wading shore birds sometimes also known as Sandpipers. Their bills are long for probing in the mud. The wings are long and pointed. The most peculiar species lives in New Zealand: its bill is sharply bent either to the right or left, near the end, enabling it to secure food from beneath stones.

North America has a number of species of plovers, such as the Kildeer Plover, abundant on the great western prairies, and not unfrequent in the Atlantic states. It utters, when approached by man, a querulous or plaintive cry.

Upland Plover (Bartramia longicauda) is the only plainly colored shorebird which occurs east of the plains and inhabits exclusively dry fields and hillsides. It breeds from Oregon, Utah, Oklahoma, Indiana, and Virginia, north to Alaska; winters in South America. It is the most terrestrial of our waders, is shy and wary, but has the one weakness of not fearing men on horseback or in a vehicle. Since the bird is highly prized as a table delicacy, it has been hunted to the verge of extermination. Ninety-seven per cent of the food of this species consists of animal forms, chiefly of injurious and neutral species. It injures no crop, but consumes a host of the worst enemies of agriculture.

Stork (Ciconia alba).—The storks are usually divided into the True Storks and the American [218] “Wood Ibises” (Tantalus). There are about a dozen species. They belong chiefly to the Old World. The most familiar representative of the family is the Common Stork or White Stork (Ciconia alba), a native of the greater part of the Old World, a migratory. bird, its range extending even to the northern parts of Scandinavia. It is about three and one-half feet in length. The head, neck, and whole body are pure white; the wings partly black; the bill and legs red. The neck is long, and generally carried in an arched form; the feathers of the breast are long and pendulous, and the bird often has its bill half hidden among them. The flight is very powerful and high in the air; the gait slow and measured. In flight the head is thrown back and the legs extended. The stork sleeps standing on one leg, with the neck folded, and the head turned backward on the shoulder. It frequents marshy places, feeding on eels and other fishes, frogs, lizards, snakes, slugs, young birds, small mammals, and insects. It makes a rude nest of sticks, reeds, etc., on the tops of tall trees, or of ruins, spires, or houses. There are four or five eggs, white tinged with buff; and the old nest is re-occupied next year.

Woodcock (Scolopax).—Their nest is formed simply by lining a sheltered hollow with dead leaves, and three or four yellowish eggs with brown markings are laid in March or early in April. The young birds are sometimes carried by the mother from place to place, and the manner of carrying has given rise to much discussion. The woodcock feeds in the early morning and at dusk on worms, beetles, small crustaceans, etc., the quantity of food consumed being very large. The adult bird measures about fourteen inches, and weighs less than one pound.

The American Woodcock (S. minor) is a smaller bird than the European species, and it also is in much request for table use. It is eleven inches in length, and is found east of the Mississippi and south of the Canadian forests.
