Common Eider

The Common Eider, known by its scientific name Somateria mollissima, is a sea duck that belongs to the family Anatidae. This bird is prevalent in regions with cold waters and can be found all around the world.

Basic Description
The male Common Eider measures about 23-29 inches long while the female reaches an average of 20-24 inches long. They have broad wings and bills of different sizes depending on their gender. The males have pinkish-white bodies with black and white feathers on their backs, while females are brown-colored.

Where To Find This Bird
Common Eiders can be found in coastal areas globally. In North America, they breed along the northern coastlines of Canada and Alaska down south to Maine during winter months. Meanwhile, they breed throughout most parts of Europe during spring.

Common Eiders prefer habitats near coastal shores; such as rocky islands or grassy marshes located close to open water where there are loads of shallow areas for them to find food. Nests are typically made up from grasses or other natural materials in secluded spots hidden away from predators like foxes or eagles.

Being a marine species, eiders feed primarily on aquatic animals such as clams and mussels which they obtain by diving into deeper depths underwater using their unique built-in air sacs that give them buoyancy when swimming.

Cool Facts
Here are some cool facts you may not know about this fascinating bird:

1) Did you know that eiderdown is used for making high-quality duvets? It’s true! The soft feathers underneath these birds’ tough outer layers provide excellent insulation against harsh weather conditions.
2) Unlike most ducks who fly low over water surfaces when migrating season arrives; eiders fly at much higher altitudes – often reaching heights greater than 10k feet above sea level!
3) Although these birds mate mostly monogamously, males have been observed engaging in what is known as “extra-pair copulation,” seeking out other females during mating season.
4) Eiders are classified under the Least Concern category on the IUCN red list of threatened species due to their stable population numbers and widespread distribution.

In conclusion, Common Eider is a unique bird that has adapted well to its marine environment. Its buoyancy capabilities make it easier for them to dive into deeper depths underwater where they can find food. These birds are widespread globally, and you may spot them near coastal shores if you’re lucky enough!
