Little Perverts

IFLScience: „Far before the sexual liberation of the 1960s, penguins were ahead of the curve by engaging in promiscuous sex between unpaired male and female penguins. There were also records of homosexual sex between male penguins.

So far, no problems by modern standards. But wait. On his Antarctic Expedition, Levick also observed instances of Adélie penguins engaging in rape, gang rape, sexual and physical abuse of chicks, as well as necrophilia with penguins, some of which had died the previous year.“
