* Due to unpassable roads 13 transects in the southeastern part 
of the Province were not'run,; hence the 1955 data are 
not completely comparable with those of previous years. 
The over-all Alberta breeding population remained practically 
unchanged from 1954 on the basis of the transects completed. Had the 13 
transects in the Tilley South area been completed the increase indicated for 
pintails might have reached significant proportions. No spectacular shifts 
appear to have taken place though a reduction from the abnormal number of birds 
in the Calgary North area in 1954 occurred, while abundant water south of the 
Old Man River in the Tilley South area led to a considerable increase there. 
Increases in the Aspen Parklands in both the Hanna Northeast and the Tofield 
Southeast areas were also recorded. 
The July 15 transects showed a small reduction in the amount of 
water on that date from that of the previous year. This was not serious except 
in the immediate Tilley-Suffield-Jenner area where some drought loss probably 
occurred,
