The Waterfowl Breeding Population and Habitat Survey (WBPHS) covers a large part of the breeding area of White-winged Scoters in western Canada. However, since the three scoter species are counted together during this survey, it is not possible to obtain an accurate estimate of the White-winged Scoter population. Based on the known extent of breeding distributions, scoter populations in the Canadian Prairies include only White-winged Scoters, while populations in Western Boreal Canada include White-winged and Surf Scoters. All three scoter species are present in Alaska. Although the species is found at very low densities in the Canadian Prairies, scoter numbers have declined over the long term based on the results of the WBPHS. Because of the lack of information specific to this species, national population goals for the western or eastern populations have not yet been determined. Detailed information on the population status of waterfowl species is available in the Population Status of Migratory Game Birds in Canada report (summarized version).
