There are several species of large diving ducks called eiders. They are heavy and round-bodied, with a humped bill that produces a characteristic sloping profile. Eiders live in the cold far north. They are the source of eiderdown, feathers that the hen plucks from her breast to line her nest and insulate her eggs. Eiderdown is used as a warm filling for jackets, pillows, quilts, and sleeping bags. Hens are mottled brown, but drakes (males) are boldly patterned, with green pigment on the head.
