Structural and functional adaptation to display in the Standard-winged nightjar Macrodipteryx longipennis

The display of the Standard-winged nightjar is described and figured. In display flight of the male the “standards” (the greatly elongated second primaries) are lifted nearly vertically above the wing, and it is probable that this is achieved aerodynamically as well as muscularly.
