Success of the Nesting Season 
Previous to 1950, it has been necessary to conclude transect observations 
about June 30, at which time banding work was started. .This year, an extension of 
time was granted for the purpose of gathering more production data before the 
hunting regulations, thus giving us one more month of observations. Indicative of 
the poor hatch in June and July is the fact that in spite of the extra month of obser- 
vations, we were still unable to locate as many broods on transects as was possible 
in only two months in 1949, In Tables 5, 6, 7, 8, and 9 below, waterfowl production 
data was secured on 449 square miles of ground and 585 square miles of aerial 
transects. This accounts for average ducks per square mile on both aerial and 
ground transects being slightly higher than the over-all average for the Province.
