Production Indices: = Brood surveys were made only in Strata A (southwestern 
Manitoba) and in the Saskatchewan Delta Area in the vicinity of The Pas. In 
Strata A the brood index dropped from 31,10) to 8,502 and in the Saskatchewan 
Delta from 9,51 to 6,739 as compared to last year. It is believed, however, 
that these indices do not represent the magnitude of the decrease that occurred. 
In the first place, the season in Manitoba was extremely late this year. In 
1952, the brood counts were made after the majority of the broods had hatched, 
while there is every indication this year that many broods may hatch following 
the survey period, Further, the vegetation this year was much more dense than 
last and it seems apparent that the aerial crews were able to see a lesser 
portion of the broods present this year than they were last. This is substan- 
tiated by the findings of ground crews in Strata A which found nearly as many 
broods this year as they did in 1952, 
Conclusions: Quoting from the field report, "..coit should be safe to assume 
that at least three=fourths as many birds will come from Manitoba in 1953 as 
in 1952."
