This strange scene was observed by a man named Keith Mo Like, who was then an education assistant in the museum, but today he is the curator. Naturally, he grabbed the camera and recorded the "love of science" of the dead duck.
Now, the first question that may come to mind is the word "why" in a large number of heart-shaped letters ... let's explain. Drakes are extremely aggressive animals. This fact, coupled with the fact that the mother duck is very picky about who is willing to mate with whom, leads to a considerable number of ducks' sexual behavior being finally * * *. Over time, this has led to random twists and turns and dead ends in the reproductive tract of the female duck, so as not to fertilize the * * * duck as much as possible.
Taken together, Drake's * * * has evolved into a relatively long and sometimes spiny spiral shape, trying to fertilize some eggs. The most extreme thing is that the length of Argentinean lake ducks is sometimes as long as the whole body, about 16- 17 inches. Why do you need to fix such a long fitting with a cork? Researchers at Alaska State University said: "Our best guess is that birds use long lassos ... males must chase females, and even females try to escape during mating."
In any case, Moeliker himself later pointed out in an appropriately titled paper that in the first autopsy case of mallard, "after the two broke up (starting from mid-March), when dragons gathered together, a dozen dragons might chase a female in the air and try to force her to come down * * * her ..."
Occasionally, once the female duck is so weak that she is forced to fall down, it will attract a group of male ducks, sometimes even fatal. ...
It is worth noting that the mother duck seems to have won the evolutionary battle on the battlefield in a sense, because the forced mating of most ducks does not seem to lead to fertilization, which is different from the situation that the mother duck finds the perfect partner and is really willing.
Going back to the dead duck example, Moeliker hypothesized that when a male duck trying to escape from the duck crashed into a window and died, two ducks might be pursuing a similar chase. 1995,
Moreover, duck experts observed that the mother duck died before the male duck, and often observed that the male duck lived before the male duck. No one has ever seen a duck have homosexual relations with dead members of the same kind. Therefore, Molik knew that this would arouse great interest of ornithologists and made a detailed record of it.
On that note, he said live ducks.
It was forcibly scraped into the duck's back and beak bottom, and most of it was scraped into the back of the dead mallard duck for about two minutes. Then load the body and start the operation. In order to mate, it worked very hard and almost kept scratching one side of its head ... He only got off the horse twice, stayed near the dead duck, scratched one side of its neck and head, and then got up again. The first rest lasted three minutes, and the second rest lasted less than one minute.
Finally, after 75 minutes, Moeliker said, "I've seen enough." "Disturbed the cruel scene." He went to collect dead ducks. He said that even then,
This corpse-addicted wild duck just reluctantly left its mate: when I approached it for about 5 meters, it didn't fly away, but simply left.
