American widgeons 
Recoveries of banded widgeons were more evenly distributed 
among the flyways than were those of any other species. The pro¬ 
portion of recoveries in Canada from widgeons banded in Alaska and 
Canada varied from 19 percent from British Columbia bandings to 25 
percent from Manitoba bandings. Hunters in Mexico and other countries 
to the south of the United States accounted for 1 to 10 percent of 
the recoveries of widgeons from bandings in most areas (tables 3 and 
13). Most widgeons from Alaska, British Columbia, and Alberta that 
were shot in the United States were harvested in the Pacific Flyway. 
Widgeons from Saskatchewan were recovered nearly equally by hunters 
in the Mississippi, Central, and Pacific Flyways, but those from 
Manitoba were taken mostly by hunters in the Mississippi Flyway. 
An important proportion of widgeons banded in Saskatchewan, Manitoba 
and Minnesota (9 to 16 percent) was recovered in the Atlantic Flyway. 
Green-winged teals 
Recoveries of banded green-winged teals were too few to determine 
their distribution from various strata. The distribution of recoveries 
from bandings in Alaska, Northwest Territories, Alberta and Saskatchewan 
is summarized in table 4. Recoveries from bandings in Alaska were 
primarily in the Pacific Flyway. About half of the recoveries from 
bandings in both Alberta and Saskatchewan were in the Central Flyway 
but recoveries in the Mississippi Flyway became relatively more impor¬ 
tant from bandings in Saskatchewan. 
Blue-winged teals 
The distribution of recoveries of blue-winged teals is summarized 
in tables 5 and 14. Harvest of blue-winged teals within the United 
States was principally within the Mississippi and Central Flyways. 
Recoveries within the United States of blue-wings that were banded in 
British Columbia were entirely in States of the Pacific Flyway, but 
with the exception of southern Alberta (stratum 26), there were no 
recoveries in the Pacific Flyway from bandings in the Prairie States 
and Provinces. However, all strata, except west-central Saskatchewan 
(21) and southwestern North Dakota (31) where samples were small, had 
a small percentage of recoveries in the Atlantic Flyway. The proportion 
of recoveries in Canada from bandings within Canada varied from about 
a third to a half of total recoveries, being highest in Alberta strata 
26 and 27. Recoveries south of the United States varied from 8.3 
percent of birds banded in North Dakota stratum 31, to 33.3 percent of 
those banded in Saskatchewan stratum 19; they were generally higher 
for blue-wings banded in Alberta and western Saskatchewan than for those 
banded in strata to the east. The decreased proportion of recoveries 
in Canada and south of the United States from birds banded in strata 
in eastern Saskatchewan and Manitoba probably reflects a high vulner¬ 
ability of blue-wings to Mississippi Flyway hunters, because first
