Forced copulations are “pervasively common in many species of ducks,” writes Prum. These are socially organized “gang rapes” that are “violent, ugly, dangerous and even deadly” and even sometimes end in the death of the female.
Do ducks forcefully mate?
Ducks do pair off to mate, however stray males often force themselves onto females. This is especially true in Mallards (wild ducks). “Rape is a normal reproductive strategy in mallards,” says Dutch researcher Kees Moeliker. Although approximately 40% of duck sex is forced, only 1 in 4 matings are successful.

The fights can last for hours before one of the ducks finally gives up. Older males are more dominant. One of the problems for males is that there are roughly two males for each female in the mallard population, so many must fight to find a mate during mating season.
Where do male ducks go after mating?
After mating, the male usually abandons the hen during the tedious time of incubation, and he seeks a secluded, food-rich spot where he will relax throughout his seasonal molt. Hybrid breeds are occurring more frequently as the mallards breed with other species such as the American black duck and the northern pintail.
