The transects indicate a gain in the number of breeding pairs in the 
Calgary area and southern part of the Province. A small loss is apparent in the 
area north-east of Tilley and a considerable reduction in the aspen parklands north 
and east of Hanna which was exceptionally heavily populated in 1951. Populations 
to the north, in the more heavily wooded areas, were almost unchanged, as was 
the over-all Provincial average. 
The number of water areas per square mile in May was somewhat greater 
than in 1951. Some of the increase was due to inclusion of more of the smaller 
types than had been done in previous years, roadside ditches, etc. The July 
transects showed water to be sufficient in all areas to bring the duck crop to 
maturity.
