Production Data 
During the nesting study a total of 39 nests were located. 
This is the smallest sample in recent years. Less manpower was avail- 
able for nest, hunting this year. Also, because of the re-nesting study 
being conducted, a smaller portion of those found was utilized for determin- 
ing natural hatching success. 
All nests located were of the black duck and ringnecked duck. 
At the present time, a few are still being incubated. Based upon the 
remainder of the sample, nesting success is running approximately the 
same as that of 1956; this is somewhat below average.
