Synopsis
Ostrich-sized rheas tramp on shoots of fields in Northern Germany. Flocks of bright green parrots screech along Cologne Cathedral. And beaver-like nutrias with orange teeth gnaw on Dutch dikes. All these animal nags are alien and are suspected of causing ecological and economic damage. Do the invaders have to be fought? Or is it just prejudice against hitherto unknown species?
This small series of three films gets to the bottom of the accusations against alien species. For this purpose, the immigrated animals are observed in their new environment, their relationships to other species are shown and the latest scientific results are presented.
