The spotted bower-bird[A] is an inhabitant of the interior. Its probable range, in Mr. Gould's opinion, is widely extended over the central portions of the Australian continent; but the only parts in which he observed it, or from which he procured specimens, were the districts immediately to the north of the colony of New South Wales. During his journey into the interior he saw it in tolerable abundance at Brezi, on the river Mokai, to the northward of the Liverpool plains; and it was also equally numerous in all the low scrubby ranges in the neighborhood of the Namoi, as well as in the open brushes that intersect the plains on its borders. Mr. Gould is gifted with the eye of an observer; but from the extreme shyness of its disposition, it generally escapes the attention of ordinary travelers, and it seldom allows itself to be approached near enough for the spectator to discern its colors. Its 'harsh, grating, scolding note,' betrays its haunts to the intruder; but, when disturbed, it seeks the tops of the highest trees, and, generally, flies off to another locality.
[Footnote A: Chlamydera maculala.—GOULD.]
Mr. Gould obtained his specimens most readily by watching at the water-holes where they come to drink; and on one occasion, near the termination of a long drought, he was guided by a native to a deep basin in a rock where water, the produce of many antecedent months, still remained. Numbers of the spotted bower-birds, honeysuckers, and parrots, sought this welcome reservoir, which had seldom, if ever before, reflected a white face. Mr. Gould's presence was regarded with suspicion by the winged frequenters of this attractive spot; but while he remained lying on the ground perfectly motionless, though close to the water, their wants overpowered their misgivings, and they would dash down past him and eagerly take their fill, although an enormous black snake was lying coiled upon a piece of wood near the edge of the pool. At this interesting post Mr. Gould remained for three days. The spotted bower-birds were the most numerous of the thirsty assemblage there congregated, and the most shy, and yet he had the satisfaction of frequently seeing six or eight of them displaying their beautiful necks as they were perched within a few feet of him. He states that the scanty supply of water remaining in the cavity must soon have been exhausted by the thousands of birds that daily resorted to it, if the rains which had so long been suspended had not descended in torrents.
Mr. Gould discovered several of the bowers of this species during his journey to the interior, the tiniest of which, now in the National Museum, he brought to England. He found the situations of these runs or bowers to be much varied. Sometimes he discovered them on the plains studded with Myalls (Acacia pendula,) and sometimes in the brushes with which the lower hills were clothed. He describes them as considerably longer, and more avenue-like, than those of the satin bower-bird, extending in many instances to three feet in length. Outwardly they were built with twigs, and beautifully lined with tall grasses, so disposed that their upper ends nearly met. The decorations were very profuse, consisting of bivalve shells, skulls of small animals, and other bones.
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.
Another species, the great bower-bird,[B] was probably the architect of the bowers found by Captain Grey during his Australian rambles, and which interested him greatly in consequence of the doubts entertained by him whether they were the works of a bird or of a quadruped,—the inclination of his mind being that their construction was due to the four-footed animal. They were formed of dead grass and parts of bushes, sunk a slight depth into two parallel furrows, in sandy soil, and were nicely arched above; they were always full of broken sea-shells, large heaps of which also protruded from the extremity of the bower. In one of these bowers, the most remote from the sea of those discovered by Captain Grey, was a heap of the stones of some fruit that evidently had been rolled therein. He never saw any animal in or near these bowers; but the abundant droppings of a small species of kangaroo close to them, induced him to suppose them to be the work of some quadruped.

Here, then, we have a race of birds whose ingenuity is not merely directed to the usual; ends of existence, self-preservation, and the continuation of the species, but to the elegancies and amusements of life. Their bowers are their ball and assembly rooms; and we are very much mistaken if they are not, like places of meeting,
