This is a normal post Technically it is rape, yes
That's how ducks breed.

Quite interesting how ducks have evolved because of mating habits. The female has evolved a corkscrew-shaped vagina to cut down on being raped, and as a result the male ducks have developed corkscrew-shaped penises to try and mate.

Bet Darwin never thought of that one!

EDIT: a bit about breeding here, though no mention of duck willies... en.wikipedia.org/wiki/Mallard#Breeding
