Ethologie der Graugans 1950 مفت لامحدود رسائي
The film gives a survey on innate behaviour patterns of the grey-lag goose. The first part shows reproductive behaviour. In the second part some behaviour patterns of gosling being imprinted on their human foster parent are shown: following reaction, separation of two flocks according to their imprinting, response to the alarm call and landing "by order" of the flying young.
