Male can adopt goslings and act as their leader and protector. Then the unloving male has to see her sit upon the eggs or, even better, with the newly-hatched goslings. She has but one chance join the male union and take part with ‘triumph ceremony’ (which means love in geese world). The lonely goose would show up just after unsuccesful mating of two males and in result, one of them would mate with her. Then she stays near the male goose and watches him, as she is unable to actively show her affection (as only males have pattern for ‘courting’ behaviour). It happens sometimes that a loner female, who has no mate of her own, “falls in love” with one of such males. Male pairs stand higher in geese hierarchy, as they are stronger, heavier and more fierce than any female. However, they would not perform any mating behaviour (or would try and fail to, because none of them performs the part of a female goose – both try to climb on top of each other, what often ends in conflict). This is how ‘triumph ceremony’ looks like Interestingly, at times two males would ‘fall in love’, meaning they would perform all pair-related behaviour, such as ‘triumph ceremony’ (they lower their heads, extend their necks forward and vocalize) and act just like a regular goose pair. Sometimes geese do not form pairs, but mate with different partners anyway. In “ The Year of the Greylag Goose” ethologist Konrad Lorenz describes curious behaviour that male graylag geese ( Anser anser) often perform.Īccording to Lorenz, in geese world “love” and “sex” are different things.
