The CLAPPER-BILLED STORKS, or SHELL-EATERS (Anastomus), inhabit Africa and Southern Asia. These most remarkable birds have a comparatively slender body, covered with short thick plumage, the head is small, the wing large, broad, and pointed, with its second and third quills longer than the rest; the short tail is composed of twelve feathers. The thick beak has its margins slightly incised, and the mandibles so formed that they only close together at the base and tip of the bill. The foot resembles that of the Stork, and the plumage is close and compact.
THE AFRICAN CLAPPER-BILL, OR SHELL-EATER.
The AFRICAN CLAPPER-BILL, or SHELL-EATER (Anastomus lamelligerus), is about the size of the Common Stork—that is, thirty-three inches long. In this bird all the feathers on the neck, belly, and legs are tipped with narrow horny little plates; these plates and the feather-shafts have a green and purple gloss. The eye is reddish, the bare bridles and throat yellowish grey, the beak yellowish, and feet black. The young are without the horny plates at the tips of their feathers, and are principally of a brownish grey. This Shell-eater is a native of Central and Southern Africa, and is met with in large flocks on the shores of the Blue River. We are unacquainted with its habits, except that it consumes fish, frogs, and molluscs of various kinds. Jerdon, however, tells us that the Anastomus osculans, a nearly-allied species, which is common in all the marshy districts of India, subsists entirely upon shell-fish. "I was formerly of opinion," says that writer, "that the open space between the mandibles was mainly caused by a process of training a Bhyri, and these, as is usual, had their eyes sewn up, to prevent their struggling or fluttering. To feed them the falconer had a quantity of the large Ampullaria brought, which were placed before the captive and blinded Shell-eaters. The bird secured a shell by its feet, and after sundry alterations of its position, succeeded in cutting off the operculum as cleanly as if it had been done by a razor, but so rapidly that I was unable to see the exact way in which it was accomplished. It then inserted the tip of its beak into the open mouth of the shell, and after working it about for a short time, pulled out the entire shell-fish, almost to its utmost tip." These birds are sometimes caught by means of a bamboo with a noose attached; this is bent down, and fixed tightly to the ground by a small peg, to which an Ampullaria is fastened. The Shell-eater, while hunting about, soon finds the shell, and in moving it to get at its contents the peg is withdrawn, the bamboo flies up, and the noose catches the bird, which remains dangling in[Pg 76] mid-air. The Indian Shell-eater breeds upon high trees about June or July, and associates in large flocks during the whole period of incubation. The eggs are four in number, and are of a dirty white. The young are defended by their parents with great courage and fierceness.
THE AFRICAN CLAPPER-BILL (Anastomus lamelligerus). ONE-FIFTH NATURAL SIZE.
The HERONS (Ardeæ) are large, ungainly birds, with a weak body, much compressed at its sides, a long thin neck, and small, narrow, flat head. The strong straight beak is as long as, or longer, than the head, compressed at the sides and culmen; the sharp margins are turned inwards, the tip is incised, and in its entire surface, except in the region of the nostrils, covered with a hard, smooth, horny coat. The legs and toes are moderately long, the claw of the centre toe being curiously denticulated on its lower side. The long, broad, blunt wing has its second, third, and fourth quills of almost equal length; the short rounded tail is composed of from ten to twelve feathers. The thick, soft, lax plumage is often much prolonged on the crown of the head and upper breast; and though strikingly and very variously coloured in the different species, is never remarkably gay. The Persians, however, catch these birds, and after depriving them of the long feathers, which are highly prized, suffer them to depart. These feathers, together with tufts of diamonds and other[Pg 77] precious stones, set in the form of Heron's plumes, adorn the dhul bandt of the Persian monarch. The members of this group are met with in most parts of the globe, migrating according to the change of seasons, or when their supply of food falls short. Swamps, shallow rivers, and pools are their favourite haunts, and in these they quietly stand, with their necks drawn down between their shoulders, watching the approach of a fish, upon which they suddenly dart, and seizing it in the beak, swallow it in an instant. They also consume small quadrupeds, frogs, and a variety of insects. Some species have been seen perched upon the backs of cattle, and feeding upon the larvæ that infest their hides. The nest of the Herons, which is usually erected on lofty trees, on elevated buildings, or among the tall reeds and river-banks, is constructed of sticks, lined with small twigs, and so loosely put together as to form a large flat expanse.
