Breeding Population Trends 
Table I shows the spring breeding population trends as computed from aerial 
results. Due to an error in interpolation of coverage, the figures for the lower 
Saint John River study area were incorrect as listed in last year's report. The 
corrected figures are substituted here,

This table shows an increase over last year in the inland transects, particularly 
in the lower Saint John River study area. The shoreline counts show a decrease. 
This decrease can be partly accounted for by the drop in black ducks in coastal 
concentrations.
