The Diamond Bird is found throughout the whole of Southern Australia, from east to west, and is still numerously met with in Van Diemen's Land. Trees and bushes are its favourite resorts, and in search of these it ventures freely into the gardens of the settlers, where it speedily attracts attention by the activity it displays in gleaning its insect fare from the leaves and branches, and by the constant repetition of its very pleasing piping note, composed of two syllables, which have been freely translated by the German settlers into the words, "Wie tief, wie tief." The most striking peculiarity, however, in this beautiful little bird is the strange manner in which it builds, the nest being placed not in hollow trees, but in holes excavated by the brooding pairs in the ground, generally on the side of some steep declivity. These excavations form galleries, or passages, usually from two to three feet long, and at their mouth are just large enough to allow the bird to pass through, whilst the lower end is made much wider, for the reception of the nest, and so raised as to insure safety from the entrance of rain. The chamber for the accommodation of the young is of a round shape, about three inches in diameter, with an entrance hole in its side. This apartment is most beautifully formed of scraps from the bark of the gum-trees, woven together with a perfection of neatness that cannot fail to astonish all who see it, if they consider that the labour of its construction is carried on entirely in the dark; the Diamond Bird affording, in this respect, a very striking contrast to such other members of the feathered creation as build under similar circumstances, their nests being, almost without exception, a mere heap of materials thrown loosely and carelessly together, without the slightest attempt at shapeliness, or endeavour to arrange the heterogeneous mass. Gould was fortunate enough to discover a number of these nests, notwithstanding the care taken by the Diamond Birds to excavate only in such localities as are completely overgrown with plants or the roots of trees. The brood consists of four or five round, smooth-shelled eggs, of a pale reddish white. The female lays twice within the year.
THE DIAMOND BIRD (Pardalotus punctatus).
The BALD-HEADED CROWS (Gymnoderi) constitute a family generally regarded as nearly allied to the Manakins (Pipræ), although differing considerably from the latter in the peculiarity of their habits and the superiority of their size, which varies from that of a Crow to that of a Thrush. The Gymnoderi are recognisable by their powerful body, (in many respects resembling that of a Crow), short neck, moderately long and pointed wings, in which the third quill exceeds the rest in length, and short tail, composed of twelve feathers, and straight at its extremity. The beak varies somewhat in different groups, but is usually flatly compressed both towards the base and at the hooked tip, which is furnished with a slight cavity, for the reception of the end of the lower mandible. The gape extends very far back, nearly to beneath the eyes. The feet, though short and strong, are only fitted for perching, and are seldom employed as means of progression. The plumage is thick, compact, and composed of large feathers, but differs so considerably in different species as to render a general description impossible. In all the members of this family the windpipe is very wide, and furnished on each side with a delicate layer of muscular fibres.
THE CAPUCHIN BIRD, OR BALD FRUIT CROW (Gymnocephalus calvus).
The Bald-headed Crows inhabit the forests of South America, and subsist entirely, or almost entirely, upon juicy fruit. In disposition they are indolent, possessed of but little intelligence, and extremely shy. Some few species are rarely heard to utter a note; but they are, for the most part, remarkable for the loudness of their voice, by which their presence is readily detected.
THE CAPUCHIN BIRD.
The CAPUCHIN BIRD, or BALD FRUIT CROW (Gymnocephalus calvus), represents one of the most remarkable of the groups into which the family of Gymnoderi is divided. The body of this species much resembles that of a Crow, with some slight variation in the different members; that is to say, the beak is considerably flatter, the feet shorter and stronger, and the toes comparatively much longer than in that bird. The slightly-pointed wings extend to the middle of the short tail; the region of the beak, bridles, and eyes, the brow, the top of the head, and the throat, are bare, and along the cheek-stripes are four stiff bristles. The plumage is compact, of a reddish brown colour, shaded with olive-green upon the back; the quills and tail-feathers are blackish brown, the secondaries tinted with red; the upper wing-covers are greenish brown; the face, beak, and feet black; and the eyes dark brown; the bare portions of the face are slightly strewn with bristles; in the young these bristles are replaced by a whitish down, and the entire plumage varies considerably, not only from that of the adult birds, but in different individuals. The body of this species measures sixteen, the wing nine, and the tail four inches.
