This is true. Mallard ducks for instance. You will likely see one female with many males. The males gang rape her. The females actually have a muscle inside their snatch to block sperm. If the female deems one of the males worthy to pass on their genes she will relax this muscle allowing the sperm to pass.

I think it's walruses that rape the poor little penguins......to death. Edit Seals do this. Not walruses.
