Ducks have diverse mating habits, like humans. They don’t have to rape, but they will when there’s overcrowding, males outcompete females, and/or they live in an urban environment where females lack the strength and space to escape.
Otherwise, most species of ducks form seasonal pair bonds with new mates each year. Some come back to the same mate each year, which isn’t quite the same as monogamy since they don’t stick together when not fucking and rearing young. A few ducks will mate for life, and a lot of larger waterfowl, like geese and swans, are monogamous.
