A baby merganser is called a "duckling." Merganser ducklings are known for their distinctive appearance, often having a mix of downy feathers and a sleek shape that helps them swim and dive. They typically stay close to their mother for protection and guidance as they learn to navigate their environment.
A merganser will eat insects, crustaceans, tadpoles, mollusks, fish, amphibians, and invertebrates it finds when diving under fresh or salt waters.
