Here are some fascinating facts about the King Eider

General Overview
Scientific Name: Somateria spectabilis.
Common Name: King Eider, referencing the bird’s regal, colorful plumage.
Family: Anatidae (ducks, geese, and swans).
Lifespan: Can live up to 20 years in the wild.
Size: Males can reach up to 26 inches (66 cm) in length.
Wingspan: Around 37 inches (94 cm).
Weight: Usually between 2.2 to 3 pounds (1 to 1.4 kg).
Habitat & Distribution
Habitat: Arctic coastal waters, tundras, and islands.
Breeding Grounds: Primarily in the Arctic regions of North America, Europe, and Siberia.
Wintering Areas: Coastal areas in northern oceans, particularly the North Atlantic and North Pacific.
Preferred Waters: Cold marine environments, often close to pack ice.
Migratory Behavior: King Eiders are long-distance migrants, covering vast distances between their breeding and wintering grounds.
Migration Distance: Some King Eiders travel over 1,000 miles to reach wintering waters.
Range: Spans across the northern hemisphere, especially around Arctic regions.
Appearance
Distinctive Colors: Males are known for their striking, colorful plumage during the breeding season.
Male Breeding Plumage: Includes bright orange, green, blue, and white on the head, with a contrasting black body.
Female Appearance: Females are more cryptically colored, mainly brown, to help with camouflage during nesting.
Bill: Males have a unique, large, orange bill with a distinctive knob on the forehead.
Molting: After breeding, males molt into an eclipse plumage, which is more subdued and resembles the female's coloring.
Diet & Feeding
Diet: Primarily consists of mollusks, crustaceans, aquatic invertebrates, and small fish.
Foraging Method: They are excellent divers, diving as deep as 180 feet (55 meters) to forage for food.
Feeding Behavior: Known to use their powerful bills to scrape mussels and other prey from rocks.
Winter Diet: During winter, their diet is dominated by marine invertebrates like snails and clams.
Reproduction & Breeding
Breeding Season: Takes place in late spring and early summer.
Nesting Locations: On the tundra, near freshwater ponds or lakes.
Nesting Material: Females build nests using grasses, moss, and down feathers.
Clutch Size: Usually lay between 4 to 7 eggs.
Incubation: The female incubates the eggs alone for about 22 to 24 days.
Nest Protection: The camouflaged appearance of the female helps her hide from predators while incubating.
Hatching: Chicks are precocial, meaning they are born with open eyes and covered in down.
Fledging: Young King Eiders fledge and leave the nest within 50 to 55 days.
Behavior & Social Structure
Social Behavior: King Eiders are gregarious, often found in large flocks, especially during migration.
Flock Size: During migration, they can form flocks of several thousand individuals.
Courtship Displays: Males perform elaborate courtship displays, including head-bobbing and vocalizations, to attract females.
Communication: Males have a distinct, cooing call, while females are quieter.
Non-breeding Males: Males that do not breed often remain together in large groups.
Unique Traits & Abilities
Excellent Divers: Known for their ability to dive deep to access food.
Adapted to Cold: Their thick feathers and a layer of fat help them survive in freezing temperatures.
Flight Speed: King Eiders can fly at speeds of up to 40 miles per hour (65 km/h).
Strong Flyers: Despite their heavy build, they are powerful flyers, enabling their long migrations.
Unique Bill Shape: The male's bill knob is thought to be an indicator of fitness and used to attract females.
Cryptic Female Plumage: Females blend into their environment, offering protection from predators during incubation.
Predators & Threats
Predators: Include Arctic foxes, gulls, jaegers, and humans.
Chick Predators: Chicks and eggs are vulnerable to predators like gulls and foxes.
Climate Change: Warming temperatures are affecting their breeding and feeding habitats.
Human Threats: Oil spills and pollution in their wintering waters pose significant threats.
