Briefly, he has shownthat birds of quite sober coloration hke the warblers, whichformed the basis of his investigations, engage in displaysquite as remarkable, and of precisely the same character asin birds of gaily colomred plumage. From this it is dearthat this wing-play is not prompted by a more or less con-scious desire to display conspicuously coloured patches ofcolour, for of colour there is none save that of the general hueof varjTing shades of brown, as in the case of the grasshopperwarbler, for example. Nor is the display, apart from colour, 64. ■ ■>*-?SS-«3S^^3^.vS,!«iteiS£,- . 5*s-v>-?gfr^;erigtf-^ to be regarded as a performance slowly perfected throughlong generations through the selection of females, coy andhard to please. We must regard these Nuptial flights and wing-displays as the outward and visible signs of a stateof ecstatic amorousness on the part of the males which, bytheir persistence and frequent recurrence, at last arousesympathetic response in the females. They play the partof an aphrodisiac. Without them there would be no my Courtship of Animals those who Will may pursue thissubject further. Before closing this chapter mention must be made ofthe most remarkable wing-display to bft found among birds,and of the equally remarkable uses to which they are possessor of these wonderful appendages, for they arewonderful, is the argus pheasant of the Malay Peninsulaand Borneo. Though efficient for short flights in jungles,all that is ever required of them, they would
