The Golden, or Six-shafted, Paradise Bird, is another rare species, first figured by Buffon, and never yet obtained in perfect condition. It was named by Boddaert, Paradisea ***pennis, and forms the genus Parotia of Viellot. This wonderful bird is about the size of the female Paradisea rubra. The plumage appear, at first sight black, but it glows in certain light with bronze and deep purple. The throat and breast are scaled with broad flat feathers of an intense golden hue, changing to green and blue tints in certain lights. On the back of the head is a broad recurved band of feathers, whose brilliancy is indescribable, resembling the sheen of emerald and topaz rather than any organic substance. Over the forehead is a large patch of pure white feathers, which shine like satin; and from the sides of the head spring the six wonderful feathers from which the bird receives its name. These are slender wires, six inches long, with a small oval web at the extremity. In addition to these ornaments, there is also an immense tuft of soft feathers on each side of the breast, which when elevated must entirely hide the wings, and give the bird au appearance of being double its real bulk. The bill is black, short, and rather compressed, with the feathers advancing over the nostrils, as in Cicinnurus regius. This singular and brilliant bird inhabits the same region as the Superb Bird of Paradise, and nothing whatever is known about it but what we can derive from an examination of the skins preserved by the natives of New Guinea.
The Standard Wing, named Semioptera wallacei by Mr. G. R. Gray, is an entirely new form of Bird of Paradise, discovered by myself in the island of Batchian, and especially distinguished by a pair of long narrow feathers of a white colour, which spring from among the short plumes which clothe the bend of the wing, and are capable of being erected at pleasure. The general colour of this bird is a delicate olive-brown, deepening to a loud of bronzy olive in the middle of the back, and changing to a delicate ashy violet with a metallic gloss, on the crown of the head. The feathers, which cover the nostrils and extend half-way down the beak, are loose and curved upwards. Beneath, it is much more beautiful. The scale-like feathers of the breast are margined with rich metallic blue-green, which colour entirely covers the throat and sides of the neck, as well as the long pointed plumes which spring from the sides of the breast, and extend nearly as far as the end of the wings. The most curious feature of the bird, however, and one altogether unique in the whole class, is found in the pair of long narrow delicate feathers which spring from each wing close to the bend. On lifting the wing-coverts they are seen to arise from two tubular horny sheaths, which diverge from near the point of junction of the carpal bones. As already described at p. 41, they are erectile, and when the bird is excited are spread out at right angles to the wing and slightly divergent. They are from six to six and a half inches long, the upper one slightly exceeding the lower. The total length of the bird is eleven inches. The bill is horny olive, the iris deep olive, and the feet bright orange.
The female bird is remarkably plain, being entirely of a dull pale earthy brown, with only a slight tinge of ashy violet on the head to relieve its general monotony; and the young males exactly resemble her. (See figures at p. 41.)This bird, frequents the lower trees of the forests, and, like most Paradise Birds, is in constant motion--flying from branch to branch, clinging to the twigs and even to the smooth and vertical trunks almost as easily as a woodpecker. It continually utters a harsh, creaking note, somewhat intermediate between that of Paradisea apoda, and the more musical cry of Cicinnurus regius.
The males at short intervals open and flutter their wings, erect the long shoulder feathers, and spread out the elegant green breast shields.
The Standard Wing is found in Gilolo as well as in Batchian, and all the specimens from the former island have the green breast shield rather longer, the crown of the head darker violet, and the lower parts of the body rather more strongly scaled with green. This is the only Paradise Bird yet found in the Moluccan district, all the others being confined to the Papuan Islands and North Australia.
We now come to the Epimachidae, or Long-billed Birds of Paradise, which, as before stated, ought not to be separated from the Paradiseidae by the intervention of any other birds. One of the most remarkable of these is the Twelve-wired Paradise Bird, Paradises alba of Blumenbach, but now placed in the genus Seleucides of Lesson.
