About This Species
The Common Merganser is a large, sleek diving duck often seen on rivers, lakes, and reservoirs, especially in colder months. Males are striking, with a dark green head, bright white body, and sharp contrast throughout, while females show a warm cinnamon-colored head with a shaggy crest and gray body. Built for fishing, mergansers are powerful swimmers that move confidently through clear water in search of prey.
