Sexuelle Prägung bei Prachtfinken Synopsis

Zebra finches and Japanese gulls are shown, as well as the rearing of young zebra finches by Japanese gulls. Despite considerable differences in the appearance of the nestlings, the gulls provide their own and the foreign young with food equally. The male zebra finches raised by the foreign species later direct their courtship behavior exclusively towards the stepparent species, i.e. they are sexually imprinted on the foreign species.
