Although so many pheasants and allied gallinaceous birds carefully display their plumage before the females, it is remarkable, as Mr. Bartlett informs me, that this is not the case with the dull-coloured Eared and opengl download Cheer pheasants (Crossoptilon auritum and Phasianus wallichii); so download online games that these birds seem conscious that they have little beauty to display. Bartlett has never seen the males of either of these species fighting together, though he has not had such download online games good opportunities for observing the Cheer as the Eared pheasant. Jenner Weir, also, finds that all male birds with rich or strongly-characterised plumage are more quarrelsome than the dull- coloured species belonging to the same groups. The goldfinch, for instance, is far more pugnacious than the linnet, and the blackbird than the thrush. Those birds which download online games undergo a seasonal change of plumage likewise become much more pugnacious at the period when they are most gaily ornamented. No doubt the males of some obscurely-coloured birds fight desperately together, but it appears that when sexual selection has been highly influential, and download online games has given bright colours to the males of any species, it has also very often given a strong tendency to pugnacity. We shall meet with nearly analogous cases when we treat of mammals. On the other hand, with birds the power of song and brilliant colours have rarely been both acquired by the males of the same species; but in this case the advantage gained would have download gimp been the same, namely success in charming the female. Nevertheless it must be owned download online games that the males of several brilliantly coloured birds have had their feathers specially modified for the sake of producing instrumental music, though the beauty of this cannot be compared, at least download online games according to our taste, with that of the vocal music of many songsters. We will now turn to male birds which are not ornamented in any high degree, but which nevertheless display during their courtship whatever attractions they may possess. These cases are in some respects more curious than the foregoing, and have been but little noticed. Weir, who has long kept download online games confined birds of many kinds, including all the British Fringillidae and Emberizidae.

The facts have been selected from a large body of valuable notes kindly sent me by him. The bullfinch download online games makes his advances in front of the download online games female, and then puffs out his breast, so that many more of download online games the crimson feathers are seen at download online games once than otherwise would be the download online games case.

At the same time he twists download online games and bows his black tail from side to side in a ludicrous photofunia download manner. The male chaffinch also stands in front of the female, thus shewing his red breast and "blue bell," download online games as the fanciers call his head; the wings at the same time being slightly expanded, with the pure download online games white bands on the shoulders thus rendered conspicuous. The common linnet distends his rosy breast, slightly expands his brown wings and tail, so as to make the best of them by download online games exhibiting their white edgings. We must, however, download online games be cautious in concluding that the wings are spread out solely for display, as some birds do so download online games whose wings are not beautiful. This is the case with the domestic cock, but it is always the wing on the side opposite to the female which is expanded, and at the same time scraped on the download online games ground.

The male goldfinch behaves differently from all other finches: his wings are download online games beautiful, the shoulders being black, with download online games the dark-tipped wing-feathers spotted with white and edged with golden yellow. When he courts the female, he sways his download online games body from side to side, and download online games quickly turns his slightly expanded wings first to one side, then to the other, with a golden flashing effect.
