CENTRAL FLYWAY 
Conclusions 
It is estimated that the decrease in breeding population will 
be balanced by an increase in production and that the 1957 fall flight of 
ducks from southern Saskatchewan will about equal that of 1956. 
The coot flight should be somewhat larger than last year. 
MONTANA 
At the time this report was written. a summary of the 
Montana surveys had not been received. However, on the basis of a phone 
conversation with Mr. Cecil Williams on July 30, it appears that the 
breeding population index for Montana this year is 133,074 birds. This 
represents a decrease of 25 percent from 1956. In view of this decrease 
in breeding population, plus the probability that habitat conditions were 
unfavorable due to drought, it is estimated that the fall Hight from 
Montana will be somewhat smaller than last year. 
WYOMING 
At the time this report was written, a summary of the 
Wyoming waterfowl survey had not been received. However, on the basis 
of a phone conversation with Mr. Cecil Williams, Central Flyway 
Representative. on July 30. it appears that the breeding populatian index 
for Wyoming this year is 139,551 birds, a decrease of 25 percent as com- 
pared to 1956. Production is above average and State technicians are 
reported to have concluded that fall flight of ducks from Wyoming would 
be somewhat greater than last year,
