The GIANT STORKS (_Mycteria_) are comparatively tall birds, with a slender body, long neck, and rather large head; the very long beak is almost straight or very slightly curved, and furnished with a saddle-shaped cere at its base, and skinny knobs or appendages beneath. The tarsi are high, and the toes short; the long and rounded wing has its third quill longer than the rest; the tail is straight, and of medium length. The sexes are almost alike in size. The young are less brightly coloured than the adult birds. Of the three species of Giant Storks with which we are acquainted, one occupies Africa, another Australia, and the third South America; these birds nearly resemble each other in their general appearance and habits. THE SENEGAL JABIRU. The SENEGAL JABIRU (_Mycteria Senegalensis_) is a large powerful bird, with the head, throat, upper wing, shoulders, and tail of a glossy metallic black; the rest of the plumage is of dazzling whiteness. In the beak the upper mandible is of very pale tint for about three inches from its base, and the under one for about one inch and a half; then comes a bar of black for about three inches, and from that to the end the bill is reddish, increasing in depth of colour to the bright vermilion tip. On each side of the upper mandible is a large semi-oval and transparent space, which at the back part is continued upwards in a curved direction across the fore part of the eyes and over the nostrils. Beneath the base of the bill, just at the beginning of the feathery part, are two very small, pear-shaped, pendent, yellowish wattles adhering by very small necks. The bare portions of the face are reddish, the eyes and eye-rings yellow; the broad movable cere is also yellow, surrounded by a narrow border of black feathers. The tarsi are brownish grey, the knee and toe-joints dull red. This species is fifty-six inches long, and ninety-two broad; the wing measures twenty-five, and the tail ten inches. In the young, all the dark parts of the plumage are brownish grey, and the under side dirty greyish yellow. Their eye is brown, and beak blackish red; the appendages beneath the beak are not developed.
