ATLANTIC FLYWAY 
Brood averages to date are running close to those of 1956. 
Although relatively few had been recorded in the important Class III age 
up to July 15, it is likely that the final tabulated figures will be very 
similar to 1956. This will be slightly higher than the long-term average, 
Satisfactory rearing conditions have been noted on a majority of the 
marshes this year in spite of a general deficiency of precipitation; most 
exceptions have occurred in the coastal belt. 
Brood data obtained thus far are summarized in the following 
table.

Conclusions 
Considering increased breeding stock, lower than average 
nesting success, but slightly better than usual rearing success, it may 
be expected that waterfowl production in northern, eastern, and central 
Maine will be slightly increased from that of 1956.
