Editing Spectacled eider (section)

==Life history==
As a diving duck, the spectacled eider forages for food in the water by swimming and diving underwater. It is believed to be able to remain submerged longer than most diving ducks and mostly feeds on mollusks while at sea and aquatic insects, crustaceans, and plant material while on the breeding grounds.

Breeding pairs are formed in the wintering grounds before spring migration through male displays and female selection. Once at the nesting sites, females build a nest close to the pond on a raised ridge, called a hummock, that are lined with plant materials and feathery down. Nests may be reused for future years. Females are the sole incubators and caretakers of the eggs and chicks and will lay on average three to six eggs with an olive buff color. Eggs are incubated for 24 days and chicks leave the nest shortly after hatching to be led to the water by the female. The female protects the chicks but they do find all their own food. Spectacled eiders have a fairly rapid development to be such large birds; it only takes about 53 days or less before they can fly.<ref>{{cite web|title=Spectacled Eider|url=http://www.audubon.org/field-guide/bird/spectacled-eider|publisher=Audubon}}</ref>
