The forest duck is a large waterfowl with a long neck. It lives in forest water bodies of South America and is distinguished by a large growth on the beak in males.
The forest duck differs from other ducks by nesting high in tree hollows. It is important for nature because it helps spread plant seeds and serves as prey for large predators.
Immature form that undergoes metamorphosis before adulthood.
