Sexuelle Prägung bei Prachtfinken
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.

From my favorite movies..
Boring
At first rather annoying in its heavy emphasis on reenactments, this movie ultimately proves fascinating, simply because the complicated, highly dramatic tale it tells still almost defies belief.
It really made me laugh, but for some moments I was tearing up because I could relate so much.
