* Assuming lone males to be territorial and to represent a pair. 
It is apparent that the waterfowl breeding population trend is down for 1954 as 
compared to 1953 and the average of the prior six years. The major portion of this 
loss occurred in the eastern area with the western loss being relatively insignificant. 
The losses for both areas appeared to have been in direct relation to the loss of 
available habitat.
