Ohio 
The wood duck was the most abundant species in Ohio 
during the first two periods (Table 21). The proportion of 
wood ducks in the kill declined greatly after the first of 
November. Mallards made up 20-30 per cent of the kill 
throughout the season. Black ducks, widgeon, lesser scaup, 
and goldeneyes had their highest incidence in the kill during 
the latest period, November 11-30. 
Iowa 
During the period of October 11-20, mallards made up 
33.3 per cent of the kill, greenwings 20.6 per cent, widgeon 
15.9 per cent, and lesser scaup only 1.6 per cent (Table 22). 
The proportion of mallards became progressively greater until 
the end of October, when it was 60 per cent. The proportion 
of widgeon appeared to decline after the. first ten days. Green- 
wings remained proportionally abundant in the kill throughout 
the season. Proportions of lesser scaup increased from 1.6 
per cent of the kill during the first 10 days to 11.2 per cent 
during the period of November 1-December 10. 
Illinois 
Mallards constituted51.3 per cent of the kill during the 
first ten days and the proportion increased to more than 80 
per cent during the final 20 days of the season (Table 23). 
Proportions of black ducks also increased steadily from 0.5 
per cent at the beginning of the season to 6.0 per cent during 
the final 20 days. Proportions of greenwings declined abruptly 
after the first period from 13.1 per cent of the kill to 0.5 
per cent by the end of the season and proportions of wood ducks 
declined from 10.5 per cent to 01.1 per cent. Diving ducks were 
relatively scarcee Proportion of lesser scaup increased from 
0.5 per cent of the kill during the first period to 7.7 per 
cent by mid-season, a pattern characteristic of the species. 
Missouri 
Mallards dominated the kill from the beginning of the 
season and their proportion increased greatly at the end of 
the season (Table 24). The next most abundant species was 
the green-winged teal, which made up about 11 per cent of 
the kill during the first 20 days of the season.
