THE SECRETARY BIRD. (Serpentarius reptilivorus.)
This singular bird, which is a native of Southern Africa, differs from all the other predaceous birds in the great length of its legs, which are so long that some naturalists have placed it among the Wading Birds. It stands between three and four feet high when erect, and is of a bluish ash colour on the back and nearly white beneath; its tail is long, and has the two middle feathers much longer than the others and nearly reaching to the ground; and the back of the head is adorned with a tuft of black feathers, which the bird can raise at pleasure. It is from this tuft that the bird has obtained his name; the Dutch colonists of the Cape of Good Hope fancied they saw some resemblance in it to the pen of a clerk stuck behind his ear, and accordingly called him the Secretary Bird. Clerks and secretaries are no doubt useful personages in their way, and the Secretary Bird, although he cannot take his pen from behind his ear, finds abundance of work to do, although of a kind very different from the peaceful labours of his namesakes. He is the great destroyer of the snakes and other reptiles which swarm in many parts of Southern Africa, and which, but for him, would increase in numbers so as to become a positive nuisance. And here we may call our young readers to admire the wonderful manner in which the structure of a hawk has been modified by the hand of the Creator to suit it for a particular mode of life. As the bird advances to attack a snake his long legs, protected by hard horny scales, elevate his body to a considerable height above the ground, thus giving him an advantageous position, and at the same time enabling it to move with great speed. One of the large and powerful wings, armed at the end with a strong spur, is raised a little from the body and held forward like a shield, but constantly shaken, as if to distract the attention of the foe, and thus, like a skilful boxer sparring up to his antagonist, the Secretary makes his way towards his intended prey. As he approaches he watches for the moment when the snake is about to spring upon him; a single blow from the spurred wing is usually sufficient to lay the reptile writhing in the ground in a helpless state; it is then soon despatched and as speedily swallowed. Some idea of the quantity of reptiles destroyed by this bird may be gained from Le Vaillant’s statement, that the crop of one of them examined by him contained eleven lizards, three snakes as long as a man’s arm, and eleven small tortoises, together with a good many insects. The inhabitants of the Cape Colony are quite aware of the services rendered to them by the Secretary Bird, and sometimes keep him among their poultry to protect them from injurious animals; he is said to behave with great propriety under these circumstances, rarely doing any mischief to his companions, unless his supply of food has been neglected.
