Before closing this Chapter mention must be made of the most remarkable wing-display to be found among birds, and of the equally remarkable uses to which they are put. The possessor of these wonderful appendages, for they are wonderful, is the argus pheasant of the Malay Peninsula and Borneo. Though efficient for short flights in jungles, all that is ever required of them, they would be quite useless in open country where an extended journey had to be made, or escape attempted from some vigorous enemy. And this because the secondary wing-quills--the quills attached to the fore-arm--are of enormous length, making, as we have remarked, sustained flight impossible. They have, indeed, come dangerously near losing their normal functions altogether. And this because they have passed over into the category of specialised "secondary sexual characters." But for the fact that this bird lives in an environment where food is abundant all the year round, and can be obtained without any undue exertion, and that there are no serious enemies to be evaded, it would long since have become extinct. For this exuberant growth of quill-feathers must be borne all the year round, though they are not required to function in their later role, save during the period of courtship. Their great length is not their only striking feature, or even their chief feature. This, indeed, is represented by their extraordinary coloration. For each feather bears along its outer web a series of "ocelli," so coloured as to look like a series of dull gold balls lying within a deep cup. Outside the ocelli run numerous pale yellow longitudinal stripes on a nearly black background. The inner web is of a delicate greyish brown hue, shading into white and relieved by innumerable black spots, while the tips of the quills have white spots bordered with black. The primaries, too, are most exquisitely coloured, though in the matter of size they are not very exceptional. These, indeed, are the only true flight feathers. The full beauty and significance of the coloration of these feathers can only be appreciated during periods of display. Then the two wings, in some indescribable manner, are opened out so as to form a huge circular screen, concealing the whole of the rest of the body. The effect produced from the human standpoint is one of great beauty, after the first burst of astonishment has spent itself. His mate is less easily moved. Perchance "familiarity breeds contempt." At any rate it is only after persistent and frequent attempts to charm her to his will that success rewards him.
