The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
Male and female birds cannot appear more different than in the case of the King Eider. The males are boldly patterned in black and white, with red and orange bills and airbrushed green and blue head feathers. Females are a perfectly camouflaged brown—important when trying to evade predators like Arctic foxes while sitting on a nest on the tundra. Audubon's climate model projects a 92 percent loss of current winter range by 2080. Many King Eiders winter mostly at sea, along cold, northern coastlines, so changes to oceans as a result of climate change will have a strong impact on the species. The summer range is not covered by the model, as data from the Arctic tundra are scarce.
