Given the ubiquity of wild ducks, one might think that the answer to this question would be clear. However, the answer is not always obvious. While some wild ducks do poop in the water, others prefer to poop on land. The main factor that determines where a duck will poop is the type of food they are eating. If a duck is eating aquatic plants, then it will likely poop in the water. On the other hand, if a duck is eating insects or other land-based prey, then it will probably poop on land. In addition, ducks may also use different areas for pooping depending on the time of year. For example, during the breeding season, ducks will often choose to nest on dry land in order to keep their eggs safe from predators. As a result, wild ducks can play an important role in dispersing nutrients both in and out of aquatic ecosystems.
