The Lesser Scaup is a small species of diving duck. Unlike the circumpolar Greater Scaup, the Lesser Scaup is only found in the Americas. Lesser Scaups breed across much of northwestern North America; they spend the winter in the southern half of the United States down into far northern South America.
Lesser Scaups breed near freshwater. Baby scaups are able to swim and even dive under water the same day they hatch from the egg!
