Common Mergansers prefer to nest near water, typically in tree cavities or on the ground. They are often found in freshwater habitats such as lakes, rivers, and wetlands, but can also be found in saltwater habitats such as coastal estuaries and bays. Their diet consists mainly of fish, but they also consume crustaceans, insects, and amphibians.

Overall, the Common Merganser is a fascinating species of waterfowl that can be found in a variety of habitats across three continents. Its distinctive appearance and migratory behavior make it a popular bird for birdwatchers and nature enthusiasts alike.
