PACIFIC FLYWAY 
The pintail populations was down 19 percent throughout the 
Province and the mallard population was up 18 percent from the 1956 
figure. Total population: indices were up only a trace from last year and 
are the second highest recorded, 1952 - 1957. There is little doubt, 
however, that because of the early leafing of the trees and appearance of 
emergent vegetation that the 1957 population may be the highest in six 
years, because the conditions under which they were observed were greatly 
inferior to those in 1955, the highest year.
