* Actual census data to closest 100, but application of species composition percentages and averages 
for periods resulted in figures used. 
Note: Harvest data on wood ducks, redheads and canvasbacks complicated by the fact that these species 
have had whole or partial protection during some of the years involved in this study, and the 
data shown here, which are based on averages, do not give a true picture of the situation. 
‘Population and kill data shown by period above are the COMPOSITE figures obtained by adding in- 
formation for all years in the period covered. They DO NOT indicate an annual population or 
kill, but are used to obtain the average kill percent for each of the periods.
