The serpent-eater is an African bird, and is not peculiar to South Africa alone, as it is found in the Gambia country. It is also a native of the Philippine Isles. There is some doubt whether the species of the Philippine Isles is identical with that of Africa. A difference is noted in the plumage, though very slight. The disposition of the crest-plumes differs in the two, and the tail-feathers are differently arranged. In the African species the two middle ones are the longest, while in the serpent-eater of the Philippines it is the two outside feathers that project—giving the bird the appearance of having a “fork” or “swallow” tail. Some points of distinction have also been observed between the South African bird and that of the Gambia.

The serpent-eater is, however, a very unique bird; and naturalists, failing to class it with either hawks, eagles, vultures, gallinæ, or cranes, have elevated it, so as to form a distinct tribe, family, genus, and species, of itself.

In South Africa it frequents the great plains and dry karoos, stalking about in search of its prey. It is not gregarious, but lives solitary or in pairs, making its nest in trees,—usually those of a thick thorny species, which renders the nest most difficult of approach. The whole edifice is about three feet in diameter, and resembles the nests of the tree-building eagles. It is usually lined with feathers and down, and two or three eggs are the number deposited for a single hatching.

The serpent-eater is an excellent runner, and spends more time on foot than on the wing. It is a shy wary bird, yet, notwithstanding, it is most easily domesticated; and it is not uncommon to see them about the houses of the Cape farmers, where they are kept as pets, on account of their usefulness in destroying snakes, lizards, and other vermin. They have been long ago introduced into the French West India Islands, and naturalised there—in order that they should make war upon the dangerous “yellow serpent,” the plague of the plantations in those parts.

Now the bird which had so opportunely appeared between Jan and Trüey, and had no doubt saved one or the other, or both, from the deadly bite of the spuugh-slang, was a serpent-eater,—one that had been tamed, and that made its home among the branches of the great nwana-tree. The hunters had found it upon the plain, wounded by some animal,—perhaps a very large snake,—and had brought it home as a curiosity. In time it quite recovered from its wounds; but the kindness it had received, during the period when it was an invalid, was not thrown away upon it. When it recovered the use of its wings, it refused to leave the society of its protectors, but remained habitually in the camp—although it made frequent excursions into the surrounding plains in search of its favourite food. It always, however, returned at night, and roosted among the branches of the great nwana-tree. Of course it was Jan's pet, and Jan was very good to it; but it now repaid all his kindness in saving him from the fangs of the deadly cobra.

The children, having recovered from their alarm, stood watching the singular conflict between serpent and serpent-eater.

On first seizing the reptile, the bird had caught it by the neck in its beak. It might not have accomplished this so readily, had not the attention of the snake been occupied by the children, thus throwing it off its guard.

Having succeeded in seizing the reptile, the bird rose nearly in a vertical direction to a height of many yards, and then opening his beak permitted the serpent to fall to the ground. His object was to stun the latter by the fall; and the more effectually to do this, he would have carried the cobra still higher, had not the latter prevented it by attempting to coil itself around his wings.

Upon letting fall his prey the serpent-eater did not remain in the air. On the contrary, he darted after the falling reptile, and the moment the latter touched the ground, and before it could put itself in an attitude of defence, the bird “pounced” upon it with spread foot, striking it a violent blow near the neck. The snake was still but slightly damaged, and throwing itself into a coil stood upon its defence. Its mouth was open to its widest extent, its tongue protruded, its fangs were erect, and its eyes flashing with rage and poison. A terrible antagonist it appeared, and for a moment the secretary seemed to think so, as he stood on the ground confronting it.

But the bird soon began to advance upon it for a renewal of the attack, though this advance was made in a cautious manner. With the pinions of one of his strong wings spread broadly out for a shield, he approached the reptile sideways, and, when near enough, suddenly wheeled, turning upon his leg as on a pivot, and struck sharply out with his other wing. The blow was delivered with good effect. It reached the head of the snake, and seemed to stun it. Its neck dropped, the coils became loosened. Before it could recover itself it was once more in the beak of the serpent-eater, and trailing through the air.
