DUCKDATA provides a comprehensive bibliography of published literature on the ecology, conservation, and management of North American waterfowl and their wetland habitats. The primary objective of DUCKDATA is to provide access to the extensive literature concerning North American waterfowl, including references emphasizing wetlands but having implications for waterfowl ecology, conservation, and management. DUCKDATA also includes selected authoritative references on wetland ecosystems to provide users with a convenient starting point for accessing this literature. References to literature published on other continents or concerning species and habitats not found in North America were included whenever possible but were not actively sought and were limited to sources published in English; hence, their coverage is less exhaustive. In selecting literature for inclusion, primary emphasis was placed on widely distributed scientific journals, books, graduate theses, and natural resource agency publications. Graduate theses were included regardless of whether the author had published results elsewhere. Inclusion of literature from less accessible sources (e.g., progress or administrative reports), popular literature, and state ornithological journals was based on perceived merit of the source in providing original data or insight into the ecology of waterfowl or wetland habitats. ...
