so excited that his eyes appear ready to start from his head, and he continues opening first one wing and then the other, uttering a low whistling-note, and seeming to pick up something from the ground, until at last the female goes gently towards him, when, after two turns round her, he suddenly makes a dash, and the scene ends.” I forgot to say that Mr. Gould once found a stone native tomahawk, amongst the heap of things that this bird had collected at its bower, and when, in Australia, either a native or a white man loses anything in the least ornamental—anything, in fact, that is not too heavy for a Bower-bird to carry—the first thing he does is to go to all the bowers in the neighbourhood, and see if it has been taken to any of them. The Spotted Bower-bird is as beautiful, perhaps, as the last, and its bower or sporting-place is a still more wonderful structure. Mr. Gould describes it as considerably longer than that of the Satin Bower-bird—three feet long sometimes—so that it is more like an avenue than a bower. “Outwardly,” he says, “they are built of twigs, and beautifully lined with tall grasses, so disposed that their heads nearly meet” (others, however, who have seen them, say that they are much more open at the top); “the decorations are very profuse, and consist of bivalve shells, crania of small mammalia, and other bones, bleached by exposure to the rays of the sun, or from the camp-fires of the natives. Evident indications of high instinct are manifest throughout the whole of the bower 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 are placed, in a heap, before the entrance of the avenue, the 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 half a bushel of bones, shells, etc., at each of the entrances.” Mr. Gould goes on to say that he “frequently found these structures at a considerable distance from the rivers, from the borders of which the birds could alone have procured the shells, and small, round, pebbly stones,” and that “their collection and transportation must, therefore, be a task of great labour.”
