Problems of Display Postures in the Charadrii (Aves: Charadriiformes)

Abstract

Studies of displays in the Charadrii (= waders or shorebirds) show that the same posture in different species, even quite closely related, may have a different function in a given context. As a corollary to this, two species even in the same genus may have quite different display postures to convey the same message.
