Compilation of the dates with regard to the early, main and 
late Canadian flights shows that the early flight arrives in Wiscon- 
sin between October 1 and October 20, the main flight between October 
10 and October 25, and the late flight between November 1 and Decem- 
ber 10. On these flights waterfowl remain in Wisconsin counties 
from three days to the freeze-up, depending upon food, open water 
and to the extent to which they are disturbed. Observers in twenty- 
four counties estimate considerable over-shooting in their counties; 
observers in twelve counties state that there is not sufficient open 
water in their counties to offer waterfowl rest and food; and thirty- 
three observers, each representing a bounty, believe that there is 
insufficient food in the waters of their counties to hold ducks in 
the respective areas. Drainage has adversely affected a large per- 
centage of the counties in the southwestern, central and southeastern 
game districts,

flight from November 1 to December 10, are listed by observers as

dance; four, canvasbacks; one, golden eyes; three, bufflehead;
