The Greater Scaup (also known as Bluebill) is a handsome, sturdy bird and a strong, fast flyer. Scaup travel from place to place in compact formations and their wings make a loud rustling sound that resembles a roar when they fly en masse. Its name is derived from its habit of feeding around oyster and mussel beds, which in Europe are called scaup beds. It also may have been named for its characteristic cry of "scaup-scaup".(see Lesser Scaup)
