Evident and beautiful indications of design (continues Mr. Gould) are manifest throughout the whole of the bower and decorations formed by this species, particularly in the manner in which the stones are placed within the bower, apparently to keep the grasses with which it is lined fixed firmly in their places, these stones diverge from the mouth of the run on each side so as to form little paths, while the immense collection of decorative materials, bones, shells, &c., are placed in a heap before the entrance of the avenue, this arrangement being the same at both ends. In some of the larger bowers, which had evidently been resorted to for many years, I have seen nearly half a bushel of bones, shells, &c., at each of the entrances. In some instances, small bowers, composed almost entirely of grasses, apparently the commencement of a new place of rendezvous, were observable. I frequently found these structures at a considerable distance from the rivers, from the borders of which they could alone have procured the shells, and small, round pebbly stones; their collection and transportation must, therefore, be a task of great labor and difficulty. As these birds feed almost entirely upon seeds and fruits, the shells and bones cannot have been collected for any other purpose than ornament; besides, it is only those which have been bleached perfectly white in the sun, or such as have been roasted by the natives, and by this means whitened, that attract their attention. I fully ascertained that these runs, like those of the satin bower-bird, formed the rendezvous of many individuals; for, after secreting myself for a short space of time near one of them, I killed two males which I had previously seen running through the avenue. The plumage of this species is remarkable. A rich brown pervades the crown of the head, the ear-coverts and the throat, each feather being bordered by a narrow black line; and, on the crown, the feathers are small and tipped with silver gray. The back of the neck is crossed by a beautiful, broad, light, rosy pink band of elongated feathers, so as to form a sort of occipital crest. The wings, tail, and upper surface, are deep brown, every feather of the back, rump, scapularies, and secondaries, having a large round spot of full buff at the tip. Primaries slightly tipped with white. All the tail-feathers with buffy white terminations. Under parts grayish white. Flank-feathers zigzagged with faint transverse light brown lines. Bill and feet dusky brown. At the corner of the mouth the bare, thick, fleshy, prominent skin, is of a pinky flesh colour, and the irides are dark brown. The rosy frill adorns the adults of both sexes: but the young male and female of the years have it not.
