Courtship behaviour of the Great Bustard Otis tarda. Male and female of this species differ in size. This exterior sexual dimorphism is emphasized by the male by presenting the light coloured underside of his wings and by blowing up the sack of the throat. In this position the male performes his courtship dance in front of a female.
