We studied captive-reared mallards (Anas platyrhynchos; CRMs) released on eastern Long Island, New York, in 2006 to 2007 and 2007 to 2008 to determine: (1) survival rates of CRMs; (2) contribution to hunter harvest; (3) local movements; and (4) pair status, reproductive behavior, and production of CRMs. We banded and released 100 CRMs in November 2006 of which 20 were radio-marked.
