4. The waterfowl breeding conditions and annual production of 
waterfowl appeared to be about the same during 1955 as it was in 1954, for

small numbers of nesting wood ducks in this area, it is difficult to determine 
if this was a local increase or a general population trend in this area of New 
Jersey.
