520	3 |a"Use by waterfowl of the Alaksen National Wildlife Area between 1973 and 1987 is presented. Thirty-four species of waterfowl were seen in and around Alaksen, of which five species are the main beneficiaries of management operations. They are Lesser Snow Goose (Chen caerulescens), Canada Goose (Branta canadensis), Mallard (Anas platyrhyncos), Northern Pintail (A. acuta) and American Wigeon (A. americana). Historical information both before and after the establishment of Alaksen is given. Dates of fall arrivals, spring departures and numbers of waterfowl on Alaksen are presented. Various crops and management operations in relation to their importance to waterfowl use are discussed as are field habitats, predators, numbers, and social behaviour. Future management and research options are presented"--Abstract, p.i.
