The SNAKE BUZZARDS (Circaëti) have frequently been numbered with the Eagles under the name of Snake Eagles. These are large birds, of a most peculiar type. Their bodies are slender, but powerful, with short neck, large head, and strong beak; the latter curves downwards from the base, is compressed at its sides, and terminates in a long hook. The wings are broad and long, the third or fourth quill exceeding the rest in length; the tail is of moderate size, broad and straight at its extremity; the feet are high, and protected by a thick armature of horny plates; the toes are very short, and furnished with short, sharp, crooked talons. The plumage is lax; and, as in that of the Eagle, the feathers upon the head and nape are pointed at their tip.
THE SNAKE BUZZARD.
THE SNAKE BUZZARD (Circaëtus brachydactylus, or Circaëtus Gallicus).
The SNAKE BUZZARD (Circaëtus brachydactylus, or Circaëtus Gallicus) is from twenty-six to twenty-eight inches long, and from sixty-six to sixty-eight across the wings; the latter measure eighteen, and the tail nine inches. The upper part of the body of this bird is brown, the feathers upon the head and nape pale brown, tipped with a still lighter shade; the quills are blackish brown, edged with two borders, one being white, the other pale brown, and marked with an irregular black line; the tail is brown, broadly tipped with white, and adorned with three black stripes; the brow, throat, and cheeks are whitish, and streaked with delicate brown lines; the crop and upper part of the breast are bright light brown; the rest of the under part of the body is white, with a few brown spots. The large eyes are surmounted with a ring of wool-like down, and the cheek-stripes are covered with bristles; the eye is yellow, the beak blueish black, and the cere and feet light blue. The young differ but slightly from the adult birds.
Until the beginning of the present century this Buzzard was almost entirely unknown, but it is now met with throughout all the countries of Southern Europe. Its habitat, however, extends beyond that continent; indeed, it often wanders far into Northern Africa, and Jerdon mentions it as common in India. In Central Europe it is a summer bird, appearing about May, and departing early in the autumn; its disposition is extremely quiet and indolent, and as it usually prefers to seek shelter in the recesses of forests, is not very frequently seen; in Hindostan, on the contrary (where it breeds), it inhabits the more open country, whether the latter be dry or marshy. In Northern Africa it flies about during the winter in parties of from six to twelve, often settling on such rocks as are near rivers, but more generally upon the open and barren steppes; it has also been known to breed in North-western Africa. The Snake Buzzards, according to our own experience, although quiet and idle, are exceedingly quarrelsome while occupied with the care of their young; at other times they are remarkably timid, and often utter loud cries if disturbed. Those we saw in Africa would remain perched when we approached, and glower at us with their large eyes in a most unearthly manner, without attempting to save themselves by flight. It is only early in the morning and late in the evening that they are seen upon trees, the entire day being spent in searching after prey. While thus employed nothing can exceed the deliberation with which they move; indeed, it would be difficult to find in any other members of the feathered race such a picture of indolence as they present, while they sit motionless at the edge of the water, or flap their way ponderously through the air. Towards its own kind this bird exhibits many most unamiable qualities, for so greedy and envious is it, that should one of its brethren prove fortunate in the chase, a hard-fought battle is sure to ensue, in order to compel the possessor of the coveted morsel ignominiously to resign its prize, and during such encounters the combatants often use their claws with so much effect that, powerless to fly, both fall together to the ground. About noon the Snake Buzzard appears upon the river banks, over which it hops much after the fashion of the Raven. An isolated tree is usually selected for a sleeping-place, as from such a situation the bird can command a view of the surrounding country.
The food of this species consists principally of reptiles, though it also devours large quantities of fish, which, should the water be shallow, it readily obtains; according to Jerdon, it also consumes rats, small birds, crabs, and the larger kinds of insects. The manner in which this bird gives battle to serpents has been thus described: "A young individual in my possession," says Mecklenburg, "would dart down upon any snake, however large or fierce, and after seizing it with its claws behind the head, bite it vigorously several times through the nape; the reptile, thus paralysed, was then swallowed by degrees, commencing with the head, each new mouthful being prepared by a preliminary bite through the backbone. During one forenoon I have seen my bird kill and devour no fewer than three large snakes, one of which measured nearly three feet, and was very thick. I have never known an instance in which it tore its prey to pieces before swallowing it. The scales were usually cast up again undigested." Elliot mentions having seen one of these Buzzards completely enveloped in the folds of a huge poisonous snake, the head of which, however, was held so firmly in the bird's beak, that all its efforts to free itself were fruitless. The thick coat of feathers in which this species is enveloped is its only protection against the deadly fangs of its victims; recent experiments have proved that its system is not, as was once supposed, proof against their poison.
The eyrie of the Snake Buzzard is built about June; it is flat in shape, and formed of branches and twigs; the interior is lined with green leaves, and green branches are also fastened outside to protect the little family from the rays of the sun. It is not uncommon for a pair of these birds to return year after year to the same eyrie. They lay one or two eggs of an oval shape, with very thin, coarse shells, of a blueish white colour. Both parents participate in the labour of incubation, sitting alternately upon the eggs for about twenty-eight days. We are told, on reliable authority, that, if molested, the mother bird removes her young to another place. The Snake Buzzard is easily tamed if taken early from the nest.
The CRESTED BUZZARDS (Spilornis) are a group of very remarkable birds, inhabiting the most southern countries of Asia and Africa. Such species as we are acquainted with are of considerable size, and powerfully built; their pointed wings, in which the fourth quill is the longest, extend to the middle of the tail; the latter is of moderate length, and rounded at the extremity; the tarsus is high, and the talons short and sharp; the beak, which is straight at the base, curves abruptly towards its tip; the margin of the upper mandible is without teeth, whilst that of the lower one is excised near the extremity. The plumage is thick, and prolonged into a crest at the back of the head.
