The flying waterbirds are web-footed birds. While they can and do swim, they are often observed flying over the water looking for food. When they find it they either pick it off the surface and keep flying, or plunge into the water from the air for food, then fly up to do it again. While the swimming waterbirds are represented by ducks, the flying waterbirds are represented by the gulls.
Flying waterbirds include Albatrosses and petrels, pelicans, gulls and terns, skuas.
