1953 count made 3 weeks earlier than previous years - not strictly 
comparable, 
There was an increase in the average brood size among both the 
dabbling and diving ducks as compared to 1952, Dabblers increased from 
6.0 ducklings per brood to 6,4 while the divers increased from 5,8 to 6.4, 
Conclusions - Spring aerial surveys showed a considerable increase in the 
‘number of waterfowl, particularly Canada geese, on the breeding ground, 
Restricted mid-summer counts, not strictly comparable with those of last 
year, indicated a successful hatch. It is estimated that the number of birds 
moving southward from British Columbia will be about the same as last year 
or somewhat greater. ie
