1958 o31 2.18 6.50 5097 

Broods seen per lineal mile were slightly below those seen the last 
three years and also fewer than the past nine-year average. The average size 
of the broods remained egual to past nine-year average. The number of bachelor 
birds was equal to the highest year on record. 
Conclusions 
Judging from this information, waterfowl production in Michigan for 
1958 was below that of 1955, 1956, and 1957, but without mich variance from 
the average for the past nine years.
