Production Indices - 
A few broods of pintails and mallards were observed the latter part of 
May, but it appears at this time that the hatching peak will be about two weeks 
later. than it was in 1955. The total number of recently hatched broods is still 
ines ons so it appears that the hatching peak has not yet been reached. 
' A total of 95 broods cs been observed on four transects approximately 
30 miles in length. Over 50 percent of these broods were hatched after July 1. 
The average brood size for the 95 broods is 7.29. 
The 1956 waterfowl production appears promising at this time, and it is 
expected that the total production will be as great as it was in 1955. 
ponclesione - 
.It is estimated that the fall flight from North Dakota will be approximately 
the same as last year.
