Winter Movements and Habitat Use by Wood Ducks in South Carolina

Ten wood ducks (Aix sponsa) were radio-tracked during the wintering period on Steel Creek, Savannah River Plant, South Carolina. Home range size, daily movement and habitat use were determined from 1,140 radio-locations. Data collected during approximately 21 to 28 days of intensive radio-tracking were sufficient for delineating individual wintering wood duck home range size.. Males had significantly larger home ranges than females (42 ha vs 12 ha) and exhibited greater diurnal movements. Females made 0.5 to 3-day excursions (N = 10) to locations outside their home ranges throughout the...
