Abstract

Nest success of overwater duck nests is generally higher than nests in upland sites. A review of the literature indicated that the major factors limiting success of overwater nests were fluctuating water levels, nest parasitism, predation, and human disturbance. Regional patterns of the occurrence of these factors could not be discerned. General management guidelines for improved recruitment and reduced nesting female mortality are suggested.
