The Cadet inhabits the northern and eastern parts of India, and is often met with in the Himalayas at an altitude of 2,500 feet above the level of the sea.
The BENT-BEAKS (Cyrtostomus) are distinguishable by their very decidedly curved beak, which equals the head in length, is blunt at its margins, and slightly incised towards its very sharp tip; the tarsus is comparatively high, the tail short and rounded, and the wings, in which the fourth and fifth quills are the longest, of moderate size. The plumage is of an olive-green on the upper parts of the body, and brightly coloured in the region of the throat.
THE AUSTRALIAN BLOSSOM RIFLER.
The AUSTRALIAN BLOSSOM RIFLER (Cyrtostomus Australis) is olive-green on the back, and of a beautiful bright yellow on the under side; the throat and upper breast are steel-blue. A short yellow streak passes over the eyes, and beneath this runs a long line of deeper shade; the eye is chestnut-brown, and the beak and feet black. The female is of an uniform yellow on the under side. According to Gould, the body of this species measures four inches and three-quarters, the wing two inches and one-eighth, and the tail two inches and a half.
"This pretty bird," says Macgillivray, as quoted by Gould, "appears to be distributed along the whole coast of Australia, the adjacent islands, and the whole of the islands in Jones's Straits. Although thus generally distributed, it is nowhere numerous, seldom more than a pair being seen together. Its habits resemble those of the Ptilotes, with which it often associates, but still more closely those of the Myzomela azura; like those birds, it resorts to the flowering trees, to feed upon the insects which frequent the blossoms, especially those of a species of Sciodophyllum. This singular tree, whose range on the north-eastern coast and that of the Australian Sun Bird appears to be the same, is furnished with enormous spike-like racemes of small scarlet flowers, which attract numbers of insects, and thus furnish an abundant supply of appropriate food. The Blossom Rifler is of a pugnacious disposition, as I have more than once seen; it drives away and pursues any visitor to the same tree. Perhaps this disposition is only exhibited during the breeding season. The nests we found at Cape York were pensile, and attached to the twig of a prickly bush; one, measuring seven inches in length, was of an elongated shape, with a rather large opening on one side, close to the top; it was composed of shreds of Melaleuca bark, a few leaves, various fibrous substances, rejectamenta of caterpillars, &c., and lined with the silky cotton of the Bombyx Australis. The eggs were pear-shaped, mottled with dirty brown, on a greenish grey ground. Another nest, found at Mount Ernest, Jones's Straits, differs from those seen in Cape York, in having over the entrance a projecting fringe-like hood, composed of the panicles of a delicate grass-like plant. It contained two young birds, and I saw the mother visit them twice in an interval of ten minutes. She glanced past like an arrow, perched at once on the nest, clinging to the lower side of the entrance, and looked round very watchfully for a few seconds before feeding the young, after which she disappeared as suddenly as she arrived."
The SPIDER-EATERS (Arachnothera) are short, compactly-built birds, with extraordinarily long and often strangely-formed beaks, which in most species are very decidedly curved and delicately incised at the margins. The nostrils are covered with a skin, and only open inferiorly, where they terminate in a horizontal slit-shaped aperture. The thread-like tongue, which is very long, and greatly resembles that of a butterfly, consists of two fine tubes, which run side by side, and are closely connected along their under surface; a longitudinal groove is interposed between them above. The arrangement of the bones at the base of the tongue, whereby the lingual apparatus is capable of considerable protrusion, is very similar to that observable in the Woodpecker. The feet are powerful, but of medium length, and the wings (in which the fourth quill is the longest) are of moderate size. The sexes are very similar in the coloration of their plumage, in which brownish green, and more or less lively yellow, grey, or green, predominate.
The Spider-eaters usually frequent the most shady retreats in their favourite woods, and but rarely ascend the branches to more than fifteen or twenty feet from the ground. In the Sunda Islands they are principally met with in the coffee plantations, the brushwood that skirts the mountains, or in the thickets of trees and shrubs that surround the villages. In all these situations they are numerous, and are constantly to be seen as they flit from flower to flower in search of the insects and honey upon which they subsist. Small spiders are said to be eagerly devoured by all the members of this family, hence their name of Arachnothera. The flight of the Spider-eaters, which is extremely rapid, and in many respects like that of the Woodpecker, is observed by the natives with a superstitious attention, fully equalling the reverence paid by the Romans to the predictions drawn by their augurs from a similar source.
