Formerly known as Oldsquaw, these ducks are one to the noisiest breeders but go quiet during migration and over the winter. Their coloring does a complete turn around too, as the seasons change. Their spring breeding plumage is mostly dark with white highlights, while their winter plumage is mostly white with dark patches.
