Mallard drake in forced copulation with duck mother
(Anas platyrhynchos) Belmont Pond, Kelowna, BC.
(Continued from Wikipedia):
...This group [of unpaired drakes] sometimes targets an isolated female duck, even one of a different species, and proceeds to chase and peck at her until she weakens, at which point the males take turns copulating with the female. Lebret (1961) calls this behaviour 'Attempted Rape Flight' and Cramp & Simmons (1977) speak of 'rape-intent flights.'
Male mallards also occasionally chase other male ducks of a different species, and even each other, in the same way. In one documented case of "homosexual necrophilia", a male mallard copulated with another male he was chasing after the chased male died upon flying into a glass window. This paper was awarded with an Ig Nobel Prize in 2003.”
