CENTRAL FLYWAY 
Production Data 
Brood survey routes for geese and ducks have not yet been estab- 
lished in Wyoming. However, in Table III a comparison is made of brood 
counts on the.Hutton Iake Refuge for the past two years. It is felt that 
these data are quite representative of the production areas on the Laramie 
Plains. It will be seen in Table III that in 1958 the number of observed 
broods increased as did the average brood size. Brood cout data are not 
available for: the remainder of Wyoming. 
Conclusions 
It appears from the data available that the fall flight of ducks 
from Wyoming will be about the same as 1957 and somewhat greater than the 
flights of 1955 and 1956. ‘The fall flight of geése will be about the same 
as 1957 but somewhat below the long-term average.
