Foods of Wintering Diving Ducks in South Carolina
T. Hoppe, Loren M. Smith, and David B. Wester
assessment of foods consumed by wintering waterfowl is essential to understand
the role wintering habitat plays in the annual cycle of waterfowl.
Past research on food habitats of wintering waterfowl in the southeast
has dealt mainly with dabblers (Anatini) (Allen 1980, Cely 1979, Glasgow and
Bardwell 1962, Hall 1962, Landers et al. 1976, 1977, McGilvrey 1966a, b,
Montalbano et al. 1979, Wright 1959) with very little research on wintering
diving ducks (Aythyini, Oxyurini) in South Caorlina (Conrad 1965, Kerwin and
Webb 1972, Montalbano et al. 1979). In
addition, most food habit studies in wintering diving ducks have not addressed
feeding ecology within and between species.
This study examines the winter food habits of three sympatric diving
ducks; Ruddy Ducks (Oxyura jamaicensis), Ring-necked Ducks (AythyaAythya
collaris), and Lesser Scaup (A. affinis), and
difference by sex, season, and species.
