.Populaticn Indices 
_ Brood counts were made on Canada geese only. Some new 
areas were censused in 1957 but will not be included here as comparisons 
with previous years would be impossible. Areas counted in 1956 and 1957 © 
are listed in the following table. The included figures are actual counts 
and no attempt was made to estimate total populations.

Count not comparable to 1956 because of more complete coverage. 
The 1957 count method will be followed in subsequent censuses of 
this area, 
These areas were difficult to count because of dese growths of 
vegetation. 
Conclusions 
In view of the decrease in breeding population of ducks and 
to the possible flooding of nests as a result of rising water during the 
nesting period, it is estimated that there will be a decrease in the fal] 
flight of ducks from Utah as compared to 1956. The flight of Canada 
geese should remain about the same.
