Abstract

Soil and water were manipulated on 4 man-made impoundments to attract rails, shorebirds, or waterfowl. Postbreeding rails were attracted by shallow flooding in late summer. Only robust vegetation that developed in early spring or withstood over-winter action by ice and feeding waterfowl provided cover for spring migrant rails. Shorebirds were attracted by draw-downs in spring, summer, and fall, and to disking and flooding in summer. Some waterfowl were attracted to impoundments managed for rails and shorebirds. Impoundments managed for waterfowl food production attracted <50% of available shorebird species and provided suitable habitat for rails and shorebirds in spring only.
