SOUTHERN ALBERTA, SOUTHERN SASKATCHEWAN, AND 
SOUTHERN MANITOBA - Continued 
to Meadow Lake and Big River there were too few water areas and 
ducks to compensate for losses farther south. Aerial surveys 
from Meadow Lake north and in the Carrot River area in the 
northeast part of the Province show a good population. There 
are no previous data in the Meadow Lake area so no comparison 
is possible but in the Carrot River area a definite increase 
over 1958 was estimated, particularly in diving species and 
principally Lesser scaup. The data collected are summarized in 
Table e. 
In southern Manitoba total breeding pairs decreased 
16.6 percent in 1959 as compared with 1958. By far the greater 
portion of this loss occurred south of Highway #1 (37.6%), 
whereas north of this route, total breeding pairs were virtually 
the same in both years (6.1% decrease in 1959). Increases in 
breeding populations were noted in only 4 species: BW? (4.9%), 
Gad. (91.8%), Shov. (8.6%), and RH (15.6%). ‘he increases in 
BWT and Shov. are probably not significant and may not be so for 
the RH. The marked increase in Gad. was noted both north and 
gouth of Highway #41, but was not pronounced in the south. 
Decreases in breeding populations were found in 8 species: Mal. 
(37.8%), Pin. (25.0%), Bald. (22.2%), Gwt (37.4%), Can. (27.0%), 
LS (10.0%), RN (37.5%), and Rud. (51.8%). Decreases were noted 
both north and south of Highway #1 for nearly all of the above 
species but they were generally more extreme in the south.
