Ducks mate by copulation, where the male climbs onto the back of the female. His reproductive organ is spiraled and grows out during the mating season. If the female duck doesn’t cooperate, it may end in fatality.

Ducks can mate either on land or in the water. The male mounts the female and holds her head in his bill. She will lift or move her tail to one side to facilitate mating, and the process may take a few seconds to get into position.

Unlike other birds, ducks actually mate like mammals. Male duck has a long spiral organ (corkscrew-shaped) that goes into the female’s genitalia and shoots its sperm in her opening. Ducks usually mate in water, and the whole mating session is very aggressive, where male duck dominates over females.

Ducks engage in a fascinating mating ritual, combining courtship displays with distinct vocalizations. The physical act of mating involves the male duck using his specialized reproductive organ to transfer sperm to the female’s oviduct. This ensures fertilization and the continuation of their species.
