Abstract
Das Männchen der Großtrappe ist wesentlich größer als das Weibchen. Der Eindruck wird bei der Balz zusätzlich verstärkt, indem das Männchen bei seinem Tanz vor dem Weibchen die hellen Flügelunterseiten zeigt und den Kehlsack aufbläst.
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.
