[Field observations on aggressive and sexual behavior of the European wild swine (Sus scrofa L.)].

This ethogram of the fighting and sexual behaviour of European wild hogs is supposed to serve as a basis for further research on the social behaviour of Sus scrofa L. The observations were recorded in writing respectively on cassette recorder as well as photographed and filmed. Behaviour patterns of the European wild hogs which were wrongly interpreted or not yet described could be documented. Being comparatively original, omnivorous social Artiodactyla, Suidae are well comparable with other Artiodactyla, with Perissodactyla, Carnivora and their domesticated types. There might also be references to the origin and development of behaviour patterns in various zoological categories or on reductions of social behaviour in domestication.
