is intended for use primarily as a guide for setting the 1957-58 shooting 
regulations. 
Inasmuch as waterfowl management within the United States is 
on the basis of four flyways, this reportis organized accordingly. In 
doing this, the flyways have arbitrarily been extended beyond the limits 
of the United States to include the breeding and wintering areas most 
closely associated with each flyway. Thus, for winter surveys, Alaska, 
British Columbia, Alberta, and western Mexico have heen considered 
with the Pacific Flyway States; Saskatchewan, eastern and central 
Mexico with the Central Flyway; Manitoba and Ontario with the 
Mississippi Flyway; and Quebec, Newfoundland and the Maritimes with 
the Atlantic Flyway. When summarizing data from the breeding grounds, 
band recovery data are used to determine the relationship between each 
breeding area and the flyways. Approximately, however, it is known 
that birds from Alaska, Northwest Territories, British Columbia, Alberta, 
and Saskatchewan are important to the Pacific Flyway hunters; that these 
Same areas excepting Alaska and British Columbia supply birds to the 
Central Flyway; that birds from northern Alberta, Northwest Territories, 
Saskatchewan, Manitoba, and western. Ontario move through the 
Mississippi Flyway; and that Alaska, northern Canada, and southern 
Canada from Saskatchewan to Newfoundland supply waterfowl to the 
Atlantic Flyway. |
