Characteristics
The Spectacled Eider is a remarkable sea duck that inhabits the Arctic regions of North America. This species has been identified by its striking black-and-white plumage and its unique bill pattern. The male’s head and neck are mostly white, with a black crown, nape and back. There’s also a distinctive white patch around the eyes giving it the “spectacled” look. Females are brown overall with some white patches on the face and wings. Both sexes have yellowish bills with black markings at the tip.
The Spectacled Eider has strong legs and webbed feet which make them powerful swimmers capable of diving for food in shallow waters. They feed mainly on crustaceans and mollusks which they locate on tidal flats, estuaries and other coastal areas. Now let’s move onto distribution and habitat of this amazing bird!
Distribution And Habitat
The Spectacled Eider is found in Alaska and its surrounding areas, breeding primarily along the coasts of Alaska and Russia. During the winter months they migrate to the coasts of western Washington, Oregon, California, and Baja California. They prefer to nest close to water in tundra or marsh environments with nearby lakes or rivers for foraging.
They are largely solitary birds during their summer residence and tend to form large groups during migration and winter season. During their winter residency they can be found in shallow bays, salt marshes, mudflats and coastline lagoons. They mostly feed on small crustaceans like shrimp, mussels, snails, clams, worms and insect larvae. Moving on to diet…
Diet
The diet of the Spectacled Eider is mainly composed of aquatic invertebrates and plant material. They forage for food at depths up to two meters, which includes mollusks, crustaceans, worms, algae, and macrophytes. During the summer months their diet consists mostly of small bottom-dwelling invertebrates like amphipods and polychaetes.
In order to survive in such cold waters, they must consume a large number of calories. To meet this need, the Spectacled Eider relies on:
- Invertebrates:
- Mollusks
- Crustaceans
- Worms
- Plant material:
- Algae
- Macrophytes
This variety in their diet allows them to maintain a healthy body weight throughout the year. By consuming both animal-based and plant-based foods, they are able to meet their nutritional requirements and stay strong. With this balanced diet comes many benefits that help the species thrive in its Arctic habitat.
Reproduction
The spectacled eider is a monogamous species that begins breeding in early May. The male will select a nesting site and then attract a female with its courtship display. Once the female agrees, they both help to build the nest, which is typically constructed of grasses, mosses, lichens, and down feathers. The female will lay 3-6 eggs over the course of several days and then incubate them for about 25 days. She is usually assisted by her mate during this process.
When the chicks hatch, both parents help to feed them for about two weeks until they are fledged and ready to leave the nest. By late June or early July, the young birds are able to fly and fend for themselves. They remain with their parents through August before dispersing into larger flocks for winter migration.
The transition from reproduction to predators and threats can be made by noting that while successful breeding increases population numbers, survival of these chicks remains dependent upon avoiding predation and other risks such as human interference or climate change.
Predators And Threats
The spectacled eider faces numerous threats from predators and human activities. The most common predators of adult birds include Arctic foxes, gulls, jaegers, ermines, and polar bears. The young are susceptible to predation by glaucous gulls, snowy owls, and ravens.
| Predator | Threat |
|---|---|
| Arctic Foxes | Prey on adults |
| Gulls | Prey on adults |
| Jaegers | Prey on adults |
| Ermines | Prey on adults |
| Polar Bears | Prey on adults and eggs/nestlings during nesting season |
| Glaucous Gulls | Prey on young birds |
| Snowy Owls | Prey on young birds |
| Ravens | Prey on young birds |
In addition to predation, the spectacled eiders population is threatened by habitat loss due to climate change, oil spills and illegal hunting. These threats have led to a decrease in the spectacled eider’s population size over the years. As such it is now listed as a species of ‘Near Threatened’ under the IUCN red list of threatened species. This conclusion leads us into our next section about conservation status.
Conservation Status
The spectacled eider is classified as a species of special concern in both the United States and Canada due to its declining population. It’s estimated that there are only between 5,000 and 10,000 individuals left in the wild. The primary threat to their survival is habitat loss from climate change. This has caused them to become increasingly rare in some areas, leading to a decrease in the number of nesting grounds available for them.
The conservation efforts for this species have been numerous, including the creation of protected marine areas along Alaska’s coastlines and increased monitoring of nesting sites by biologists. There have also been educational campaigns designed to raise awareness about the importance of conserving these birds, as well as encouraging eco-tourism opportunities for birdwatchers that help support local communities. All of these efforts have helped slow down their decline, but more needs to be done if we want to ensure their continued survival into the future.
As such an iconic species, it’s important that we continue to work towards preserving them so they can remain a part of our environment and bring joy to generations to come. With some interesting facts about this beautiful bird ahead, let’s take a look at what makes it so unique.
