Pair fidelity often develops, leading to strong social bonds.

Such mate choice helps both partners contribute to a successful family life—a feat as daring as riding ocean waves!

Nesting Sites and Materials

When choosing a nest site, Surf Scoters play it safe by opting for well-hidden spots away from water. They nest under low tree branches or dense grass, creating a shallow depression lined with down.

This concealment helps fend off predators and improve nest success, ensuring their eggs remain undetected and their offspring thrive.

This approach ensures that their eggs remain undetected, and as a result, their offspring are more likely to thrive.

Egg Laying and Incubation

Once the nest site is selected, the female surf scoter lays a clutch of 4-9 camouflaged eggs.

She then diligently incubates the eggs for 28-30 days , rarely leaving the nest to forage.

This dedicated parental care boosts the best chance of hatching success for the next generation of these remarkable sea ducks.

Female and Duckling Care

Watching a mother Surf Scoter with her ducklings is pure magic.

Her maternal instincts shine as she leads her brood to water shortly after hatching. Ducklings feed themselves, relying on their plucky independence. Yet, she’s always there, ready to defend against threats and guide their chick development with care.
