ATLANTIC FLYWAY 
Table I indicates a rather severe decrease in production for 
approximately 50 percent of the 121 comparable areas. In some instances 
this decrease was very small. 
Table II from the 110 comparable areas shows a decrease in pro- 
duction for all species except the Ring-necked duck. Brood size is up 
for all species while the number of young birds shows a decrease. ‘This 
could be due to the greater rearing success of the June hatched broods. 
Conclusions 
Interpretation of the data is difficult but pessimistic as 
follows: 
Black duck - slight to moderate decrease 
Wood duck - no change 
Mallard - slight decrease.
