The REED KITE, or MARSH HARRIER (Circus rufus), closely resembles the birds above described in its general construction, but its beak is longer and more powerful, and its tarsi more robust; the facial disc, moreover, is only slightly indicated. Its length is twenty-one inches, of which ten belong to the tail; its breadth varies from forty to fifty inches. The female is from one and a half to two inches longer, and three broader than her mate. The plumage of the adult male is often much variegated. The top of the head and brow are brown; the cheeks and throat are covered with pale yellow feathers, having dark shafts; the upper part of the breast is yellow, streaked with brown, and the feathers on the under part of the body are rust colour, tipped with a light shade; most of the secondary quills, and all the tail-feathers, are grey. In the female the top of the head and nape are yellow, striped with brown, the rest of the mantle is reddish brown; the shoulder and upper wing-covers of the axillary region are yellow, streaked with brown; the throat is yellow, the cheeks and fore part of the body reddish brown. The young are usually dark brown, with yellow heads, but vary much in their plumage. The feet of all are pale yellow; the beak is black; the eye of the adult bird yellow; that of the young, nut brown. It is at present uncertain to what countries the habitat of this species is restricted, as it has been occasionally met with in many parts of the world. Marshy districts afford its favourite retreats, and it is constantly seen in the vicinity of water or bog land, carefully avoiding high, dry plains, or mountainous regions. During the winter this Harrier is one of the commonest birds of India and Egypt. It reaches Europe about March, and at once takes possession of its appropriate haunts. In its mode of life and habits it so closely resembles the Blue Kite that further description would be mere repetition. Its food consists principally of water and marsh birds, frogs, fish, and insects; according to Jerdon, it will also eat shrew mice and water rats. Large eggs it opens with great dexterity, small ones are devoured whole; with Swan's eggs it appears to be unable to grapple, for Naumann mentions having seen a Reed Kite turning them over, and vainly endeavouring to get at the interior: it is no doubt from fear of this voracious enemy that many birds are at such pains to conceal their nests. From the breeding season until autumn this species pursues all kinds of Water Fowl with insatiable avidity; it is in vain that the quarry endeavours to elude pursuit by diving; old Ducks alone seem capable of chasing away the unwelcome intruder, who, however, revenges itself for their temerity, by destroying all the unprotected ducklings that stray into its vicinity. In India this bird often exhibits great hardihood; indeed, it is not uncommon for it to seize upon a Snipe at the very moment that the sportsman is about to fire. The eyrie is formed in beds of reeds, and is a mere rude mass of flags, rushes, or similar materials carelessly heaped together. The brood consists of from four to six large greenish-white eggs, which are hatched by the female alone, who is meanwhile entertained by the antics of her mate; the latter amusing himself by performing every conceivable kind of vagary in the air, accompanying his motions by alternately lively and lugubrious cries for whole hours at a time. The young are tended with much care by both parents. As may be imagined, the enemies of the Reed Kite are neither few nor backward in their attacks; the flocks of Crows alone must occasionally make its life wearisome, for they allow no opportunity of annoying or pursuing it to escape their vigilance. In some parts of Asia the Reed Kite is trained to hunt Ducks; but in Europe, as far as we are aware, this has never been attempted.
Several species of Kites inhabiting New Holland, are distinguished from those already described by their plumage. These birds have been grouped together under the name of SPOTTED KITES (Spilocircus).
JARDINE'S SPOTTED KITE.
JARDINE'S SPOTTED KITE (Spilocircus Jardinii) is about the size of the Reed Kite. The feathers upon its cheeks, ear-covers, and the top of its head are nut brown, streaked with blackish brown upon the shafts; the face, breast, and back are dark grey; the under side of the wings, belly, and legs are reddish brown; most of the feathers upon the wings and lower part of the breast are marked with round white spots upon each side of the shaft; the quills are dark, and the tail-feathers striped alternately with brown and grey. The beak is grey at the base, and black at its tip; the feet are yellow, and the eyes orange. The young birds are of an uniform dark brown upon the back, and striped instead of spotted on the lower parts of the body. Gould informs us that the Spotted Kite is found extensively throughout New South Wales, and that it closely resembles its European congeners in its habits and mode of life. Small quadrupeds, birds, lizards, and snakes constitute its principal nourishment. The nest is built upon the ground.
The BUZZARDS (Buteones) constitute a group of somewhat heavily-constructed birds, of moderate size, that are found extensively in both hemispheres, and in almost every latitude. Their bodies are stout, their heads broad, thick, and flat; they all have short beaks, which curve downwards from the base, are comparatively thick at the sides, and without denticulations on the margin. Their necks are short, and their wings long and rounded; in the latter the fourth quill usually exceeds the rest in length. The tail is of moderate size, the tarsi of no great height, and furnished with short, weak toes, which are, however, armed with sharp and formidable talons. The plumage is more or less lax, and composed of long, broad feathers, except upon the head, where they are narrow and pointed, being only exceptionally prolonged into a crest. Dusky hues predominate in the coloration of these birds, and their markings are numerous and very varied.
The Buzzards frequent both mountainous and level districts, preferring, however, such situations as abound in fields and woodlands. During the breeding season each pair takes up its abode in a certain limited district, within which it keeps, never trenching upon the space belonging to a neighbouring couple. Towards other members of the feathered creation they are inoffensive and peaceable, and are only roused to violence should an intruder venture too close to their young family; such as inhabit the northern countries of Europe are migratory in their habits, while those found in southern regions are stationary. All the various species fly slowly, more after the manner of the Eagles than of the Kites; when about to pounce upon their prey, they hover, Falcon-like, for a moment in the air, and then come slowly and heavily down. Upon the ground their movements are ungainly, and their step an awkward attempt at a hop. So strong and keen is the sight of these birds, that they may be very properly termed "eagle-eyed;" their hearing is also good, and their powers of touch and taste well developed.
In spite of the apparent dullness exhibited by the Buzzards, they are superior in intelligence to most of their order, and scarcely deserve to be called rapacious, as when no longer hungry they rarely plunder from mere love of theft; having satisfied their appetite, they seem to trouble themselves no longer about the chase. With other Birds of Prey they would willingly live upon amicable terms; towards the Screech Owl alone they exhibit a most implacable hatred. But the Buzzards themselves have many tormentors, no doubt from the fact that such of their assailants as are light and active find considerable amusement in following and worrying their more ponderous and unwieldy neighbours. Worms, snails, larvæ, and various kinds of insects, together with some kinds of vegetable food, are eaten in large quantities by these birds, so that their services to the farmer are both extensive and important. Rice they will readily devour, and snakes they perseveringly destroy, even if the encounter necessitates considerable exertion. Their eyrie is built in high trees, and constructed in the most careless manner; the eggs are usually three or four in number, though occasionally the female lays but one. The young remain for a considerable time under the care and tuition of their parents, by whom they are most watchfully tended. If taken from the nest when very young, the Buzzard will become so tame that it may be allowed to fly about at large.
