Lesser Scaup, Aythya affinis, is a duck of North America, breeding from south-west Alaska mainland to California and also in west Quebec and west Minnesota, and moving south to Central America and the Caribbean outside the breeding season. It is a diving duck and is known for its blue bill, which has given rise to the names little bluebill and broadbill. The species was described by Eyton in 1838. Its scientific name reflects its relationship to the greater scaup.
