* Species composition determined from ground counts made 
immediately following aerial counts. Species indices 
for each area corrected for non-breeding ducks and 
for hens nesting not observed, but represented by 
lone males. 
Production Indices - 
Table 3 presents the only data available on production trends. 
As no breeding pair counts were made in mid-June, no brood per pair 
comparison is available. However, observations indicate very good nesting 
success for most species.
