From the author: We examined the use of wetland habitats by female Mallards (Anas platyrhynchos from March 1990 through July 1992 in the St. Lawrence River Valley, a focus area under the North American Waterfowl Management Plan. Female Mallards spent most of their time breeding in forested-live wetlands (40%) and postbreeding in forester-dead wetlands (35%). According to wetland availability data, breeding and postbreeding females indicated selectivity for emergent and scrub-shrub wetlands. During postbreeding, they used fewer ([Mathematical Expression Omitted] = 2.6, [+ or -] 0.2 [SE]) individual wetlands of larger size ([Mathematical Expression Omitted] = 192 ha [+ or -] 30 ha) compared to the breeding season ([Mathematical Expression Omitted] numbers = 4.1 [+ or -] = 0.2, P = 0.003; [Mathematical Expression Omitted] size = 101 ha [+ or -] = 15 ha, P = 0.001). Moreover, females typically spent the postbreeding season in the vicinity of, or within, their breeding wetlands, hence conservation must simultaneously address breeding and postbreeding requirements. Protection of wetland complexes that contain a diversity of habitat types of differing sizes is recommended. Received 29 March 1994, accepted 1 Oct. 1994.
