These two species have different preferences when it comes to their habitat. The Red-breasted Merganser is more adaptable, often found in coastal waters, lakes, and rivers. It has a broad range, spanning across North America, Europe, and Asia.
In contrast, the Common Merganser prefers freshwater lakes and rivers. It is widespread across North America and Eurasia. If you live near a large lake, chances are you’ve seen a Common Merganser gliding gracefully across the water.
Have you ever wondered why these birds choose different habitats? It’s all about the availability of their favorite prey – fish. Each species has adapted to thrive in environments where they can easily catch their meals.
Understanding their habitat and range can help you spot these birds in the wild. Next time you’re near a body of water, keep an eye out for these elegant divers. You might be surprised at what you find.
Physical Characteristics
Red Breasted Mergansers and Common Mergansers have distinct physical traits. These differences help bird watchers identify them easily. This section explores their size, weight, and plumage.
Size And Weight
Red Breasted Mergansers are medium-sized ducks. They range from 20 to 25 inches in length. They weigh between 2 and 3 pounds. Common Mergansers are slightly larger. They range from 23 to 28 inches in length. They weigh between 2.5 and 4.5 pounds. This size difference is noticeable in the wild.
Plumage Differences

The plumage differences are clear. These differences make it easy to tell the species apart.
Behavioral Traits
When comparing the Red-breasted Merganser to the Common Merganser, their behavioral traits offer fascinating insights. These two species, though similar in appearance, exhibit distinct habits that set them apart in the wild. Understanding their feeding habits and migration patterns helps bird enthusiasts and casual observers alike to distinguish between them.
Feeding Habits
Red-breasted Mergansers are often seen diving swiftly and deeply for their meals. They primarily feed on small fish and can be quite the acrobats underwater. You might spot them hunting in coastal waters or large lakes, sometimes in groups, making a splash as they pursue their prey.
In contrast, Common Mergansers prefer calmer waters such as rivers and freshwater lakes. Their diet is similar, consisting mainly of fish, but they also add crustaceans and aquatic insects to their menu. Watching a Common Merganser hunt is a lesson in precision; they glide smoothly and strike with remarkable speed.
Migration Patterns
Red-breasted Mergansers are known for their extensive migration journeys. They breed in the northern regions of North America and travel south during the winter. You might find them along the coasts of the United States, enjoying the warmer climates.
Common Mergansers, on the other hand, have a slightly more conservative migration pattern. They also breed in northern areas but tend to migrate shorter distances, often moving to nearby unfrozen bodies of water. If you live near a large river or lake, chances are you might see these elegant birds year-round.
Have you ever noticed these fascinating behaviors in your local waterfowl? Observing their unique traits can be a rewarding experience. It’s amazing how much you can learn by simply paying attention to the birds around you.
