It’s a type of sea duck with beautiful black, white, blue, and russet feathers that stand out in any environment. But beyond its striking features, there’s much more to learn about Steller’s Eider. Let’s take a closer look at this unique species and explore why it has captured the attention of so many people around the world.

Steller’s Eider is one of the most sought after birds for birdwatchers and wildlife enthusiasts alike. Once seen as a rare sight, its numbers have increased over recent years due to conservation efforts. Its unique plumage makes it easy to spot in its natural habitat on shorelines or small islands near the ocean. Despite being considered vulnerable by birdlife experts, Steller’s Eider continues to thrive in many parts of the world thanks to ongoing conservation efforts.

The behavior and diet of Steller’s Eider also make it an interesting species for study. They feed mainly on mollusks, crustaceans, and insects that can be found in shallow coastal waters or estuaries. While not strictly migratory birds, they do prefer warmer climates during winter months which could explain why sightings are more common during these times.


Steller’s Eider is a sea duck that breeds in the Arctic tundra of Alaska and Russia. It’s a small duck, with males being approximately 21 inches long and weighing in at about two pounds. During the winter months, it migrates south to the coastlines of Alaska and northern Japan. Steller’s Eider is classified as ‘Vulnerable’ by the IUCN Red List due to its small population size, limited range, and threats from habitat destruction and pollutants.

The species has an interesting life cycle; during the breeding season, both parents take turns incubating the eggs before they hatch. After hatching, both parents feed their young until they are old enough to fly south for the winter.

This section has provided an overview of Steller’s Eider; now we’ll look more closely at its distribution and habitat.

Distribution And Habitat

It has been suggested that Steller’s eider thrives in colder climates, but do they really prefer such frigid temperatures? Though it is true that they are partial to colder climates, Steller’s eiders can be found throughout the Arctic. They breed in Russia, Alaska, Canada and Greenland and spend their winters in the northern U.S., Canada and Greenland.

Steller’s eiders typically inhabit shallow tundra ponds and coastal bays. They also reside on sheltered bays with plenty of vegetation. The birds feed mainly on mollusks, crustaceans and insects, which are abundant in these habitats. With its preference for cold weather and abundance of food sources, Steller’s eider is able to thrive in its natural habitat. Onward to diet and feeding habits we go!

Diet And Feeding Habits

Steller’s Eiders feed primarily on crustaceans, aquatic insects, and mollusks. They dive underwater to find their prey, reaching depths of up to 20 meters. They also occasionally feed on small fish and larvae. During breeding season they dive more often than in other times of the year as they need to keep up with the energy demands of incubation and chick care.

Steller’s Eiders are also known to scavenge for food from fishing boats in areas where they have been habituated to humans. This behavior has caused them to become vulnerable to overfishing or being caught as bycatch in fishing nets. To protect these birds from harm, it is important that conservation efforts focus on protecting their habitat and limiting human disturbances near their nesting grounds. With this, Steller’s Eiders will be able to continue feeding safely without any further risk of harm.

Steller’s Eider breeding and nesting behavior is essential for understanding how these birds survive in the wild.

Breeding And Nesting Behavior

The breeding season for Steller’s eider is quite brief, lasting only two or three months. During this time, the birds migrate to the northern tundra of Alaska and Canada, where they nest in colonies. In order to build a nest, the female will use grasses to line a shallow depression in the ground.

When it comes to nesting behavior, Steller’s eiders exhibit some interesting characteristics:

  • They are monogamous and typically stay with one mate for life
  • The male helps incubate eggs and care for chicks
  • They will often lay their eggs in another female’s nest if their own is destroyed or lost

The maintenance of nesting sites is critical for the survival of this species. As such, conservation efforts must ensure that adequate habitat remains available year after year. With these efforts in place, Steller’s eiders may be better able to successfully breed and rear young on their breeding grounds. This sets the stage for them to undertake their annual migrations in search of food resources.

Migratory Patterns

Steller’s eider is a migratory species. It breeds in the Arctic tundra regions of Alaska and Canada during the summer months, then migrates south to the coasts of northeastern North America in the wintertime. During their annual migration, they travel hundreds of miles along flyways, often stopping at important coastal staging areas along the way. These staging areas provide refuge and food for them during their long journey south.

The length of the Steller’s eider’s migration varies depending on where it breeds and where it winters. Those that breed in Alaska may travel over 3,000 miles to reach their winter home on the East Coast, while those from Canada may only migrate a few hundred miles. No matter how far they travel, though, these birds make sure to return to their breeding grounds each year to raise their young. Next we’ll look at the conservation status of this species.

Conservation Status

The Steller’s Eider is in a bit of a pickle. It is classified as ‘Endangered’ on the IUCN Red List, with its population estimated to be rapidly declining. The main threats to this species are human disturbances such as hunting, habitat loss and degradation due to climate change, and entanglement in fishing nets. All of these factors have put the Steller’s Eider in hot water.
