Ring-necked Duck

Ring-necked Ducks might better be named the Ring-billed Duck. Males sport a brownish ring around their necks, almost visible at the base of the drake's neck in the bottom photo. Perhaps the best field mark is the bright white stripe that contrasts withe the drake's dark breast, black back, and gray sides.
Pairs of Ring-necked ducks stick together, at least until mating is finished.  Pairs form during spring migration--these pairs were taken near Circle Lake in Rice Co., Minnesota, on 1 April 2011.  Only the female, however, cares for the young (at least until they fledge). Ring-necked Duck populations increased during the 1980s and early 1990s.  This increase is odd, since other prairie-nesting ducks declined during this time (Hohman and Eberhardt 1998)
