Loss of delta wetlands is occurring at an accelerated pace through hydro-electric flooding and agricultural drainage (Smith,Dufresne, and Hansen, 1964), and this study of nesting success represents one phase of a larger study to evaluate the importance of such wetlands to waterfowl. Species selection of nest sites, dates of nest initiation and hatching, average clutch sizes, and nesting success were determined to provide background information useful in developing managment procedures for marsh areas of the Saskatchewan delta. The study area was part of a large marsh formerly managed for muskrats (Ondatra sibethicus) by the Hudson's Bay Company, and presently under joint management for muskrats and waterfowl by the Saskatchewan Department of Natural Resources and by Ducks Unlimited (Canada). The marsh (known locally as the furlease) lies s
