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 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. [Illustration: GROUP OF HERONS.] THE COMMON HERON. The COMMON HERON (_Ardea cinerea_) represents a group possessing a thin body, long neck, long powerful beak, and plumage of more or less sombre appearance. In the adult birds the crown and brow are white, the neck greyish white, the back ash-grey, varied by the white of its long feathers; the sides of the lower parts are black; a stripe from the eye to the nape, three long crest-feathers, a threefold row of spots on the front of the neck, and the large quills, are all black; and the upper secondaries and tail-feathers grey. The eyes are golden yellow, the bare patches on the face greenish yellow, the beak is straw-colour, and the foot brownish black. This species is forty-two inches long and seventy-five broad, the wing nineteen and the tail seven inches. The young are greyer than the adults, and have no crest.
