The Yamal Peninsula on the coast of the Kara Sea in the Yamal-Nenets autonomous region hosts most of the King Eider population in Russia. The region is mostly uninhabited, and King Eiders are the dominant bird species there.
- Canada: Most of the King Eider population in Canada breeds on the Arctic coastline of Baffin Island. The ducks make use of the low-lying coastal areas, estuaries, bays, and small islands close to the mainland. Other breeding locations include the Beaufort Sea coast in the Northwest Territories, the Hudson Bay coastline in Manitoba, and some parts of Nunavut.
- Alaska: The Alaskan breeding grounds of King Eiders span from the edge of the Arctic Ocean to the Bering Sea. The North Slope coastal region of Alaska hosts mostly all the breeding eider. The ducks typically nest on mid to large-sized lakes that often become unaccessible once winter sets in.
King Eiders are connected to these breeding sites and the environment specific to them. To identify potential breeding areas, they tend to return to specific sites, whether from yearly migrations and even revisiting areas from their own hatching. Once breeding sites are identified, nesting and breeding activities can begin. This enhances the reproduction cycle. The ducks hatch their chicks in the summer, usually from June to late July. This wave of hatchlings also attracts predators. So the ducks party to hide their young, or they will become a meal for foxes, jaegers, and gulls.
The preservation of these breeding grounds is of vital importance to the King Eider species. With the ever-increasing human presence in the Arctic, natural habitats for these ducks are threatened, and destabilisation of their ecosystem could potentially wipe out the population of King Eiders.

Threats to King Eider Populations
The King Eider (Somateria spectabilis) is a sea duck that can be found in the northernmost areas of North America, Europe, and Asia. In North America, King Eider populations breed in the Arctic tundra and take to the sea during the winter season, migrating as far as the eastern coast of the United States.
- Climate Change – The Arctic is warming more than twice as fast as the global average and these changes can have a significant impact on King Eider populations. For instance, the sea ice cover is shrinking, thus reducing the amount of foraging habitat available and ultimately leading to a negative impact on the duck’s population.
- Oil Spills – Oil spills can have catastrophic effects on the birds’ habitat. Studies have shown that oil spills can harm King Eiders in several ways, including poisoning through ingestion of polluted prey, smothering from oil on feathers, and habitat destruction. Due to their reliance on Arctic waters, King Eiders are highly vulnerable to oil spills, and special attention should be given to their habitat to avoid any risk of disaster.
- Loss of Habitat – King Eider populations depend on a delicate balance between offshore and coastal habitats. Coastal developments such as industrial, residential, and recreational activities can reduce the birds’ foraging areas and the number of available nesting and breeding sites. Coastal habitat loss also exposes the birds to human disturbance which can lead to a decline in their population.
The impacts of these threats are worsened by the King Eiders’ long life cycle and slow reproductive rate. The birds don’t reach sexual maturity until they are at least three years old and once they do, they produce only one or two eggs per year. Given the long-distance migration patterns of these birds, they require a stable and predictable environment, which is threatened by environmental changes.
In conclusion, mitigating these threats to the King Eider’s population is essential to their continued survival. Establishing protected areas of habitat, limiting offshore drilling and other industrial activities, and reducing carbon emissions can help ensure that these birds remain a part of our world’s natural beauty for future generations to appreciate.
