Summary and Conclusions 
1, The survey area located in Ontario, northern Manitoba and 
northern Saskatchewan involves a total of 549,320 square miles. A coverage of 
1728 square miles was accomplished during May, and 1809 square miles during 
July. 
2. The phenology of the season was advanced over 1954. While the 
weather during May was not ideal, no severe storms affected the area. During 
July, weather and water conditions were about as ideal, especially in Manitoba 
and Saskatchewan, as can be expected. 
3. Ona strata basis the following information was computed relative 
to total ducks: 
Stratum C Ontario - decrease 14 percent 
Stratum C Manitoba - decrease 10 percent 
Stratum D Manitoba - increase 165 percent 
Stratum C Saskatchewan - increase 69 percent 
4. Organized by Provinces, the following information was obtained: 
Ontario - 14 percent decrease from 1954 
Manitoba - 35 percent increase from 1954 
Saskatchewan - 69 percent increase from 1954 
5. As a whole,an increase of 28 percent above 1954 in total ducks 
is indicated for the entire area. Only black ducks, blue-winged teal, shoveler, 
and goldeneye showed a definite decrease. Scaup and ring-necked ducks recorded 
a definite increase. 
6. The total Canada poose population for the entire area was 
computed to be only about 25,000 birds. This population. decreased approximately 
17 percent from 1954, 
7. In Manitoba and Saskatchewan the number of young increased 
148.9 percent over July 1954. Ontario could not be included in the comparison 
because it was not sampled in July 1954. 
8. An increase in potential later broods of 115.3 percent over 1954 
was also recorded for the same area during July. 
9. In spite of this increase there appeared to be no significant 
change in brood age from 1954. 
10. Canada geese observed during July, including young and adults, 
increased 191.3 percent over July 1954 in Manitoba and Saskatchewan.
