Production Data - 
Although a comparable production survey was not conducted in 1956, 
it seems likely that the late season will reduce the number of young somewhat. 
Conclusions - 
It is estimated that a probable reduction in production will balance the 
small increase in breeding population of ducks and that the fall flight. will be 
about the same as last year.
