The '''lesser scaup''' ('''''Aythya affinis''''') is a small [[North America]]n [[diving duck]] that migrates south as far as [[Central America]] in winter. It is colloquially known as the '''little bluebill''' or '''broadbill''' because of its distinctive blue bill. The origin of the name scaup may stem from the bird's preference for feeding on scalp—the Scottish word for clams, oysters, and mussels; however, some credit it to the female's discordant scaup call as the name's source.<ref name=DUb/> It is apparently a very close relative of the [[Holarctic]] [[greater scaup]] or "bluebill" (''A. marila''), with which it forms a [[superspecies]].<ref name = carboneras1992 /><ref name=Livezey/> The scientific name is derived from [[Ancient Greek]] and [[Latin]], with ''aithuia'' being an Ancient Greek term for an unidentified [[seabird]], used by [[Hesychius of Miletus|Hesychius]] and [[Aristotle]], among other authors, and ''affinis'', Latin for "related to", from the lesser scaup's resemblance to the greater scaup.<ref name= job90>{{cite book | last= Jobling | first= James A | year= 2010| title= The Helm Dictionary of Scientific Bird Names | url= https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling | publisher = Christopher Helm | location = London | isbn = 978-1-4081-2501-4 |pages = [https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling/page/n35 35], 64}}</ref>
