Podicipitiform seabirds are aquatic birds that are typically found in freshwater or nearshore marine environments. These birds are often called grebes, and they are known for their small size and agile swimming abilities. Synonyms for podicipitiform seabird include waterfowl, waterbird, and diving bird. These seabirds are characterized by their sleek, streamlined bodies and their ability to dive and swim underwater to catch fish and other prey. In addition to grebes, other podicipitiform seabirds include loons and auks. These birds play an important role in aquatic ecosystems, helping to maintain the balance and health of marine and freshwater ecosystems.
