Tf estimated; this table was compiled before results for the fall of 
1946 were available; the additional birds shot in subsequent years 
should not importantly affect the mortality rates calculated here. 
- Munro (1943) has reported that females rather consistently 
exceeded males in numbers banded by A. J. Butler in British Columbia, 
the sex ratio for 13,959 mallards being 5.7 per cent males against 
5.3 ver cent females. "Banding recoveries show that more females 
are shot than males; in a 12-year period the numbers recorded were 
1299 females and 1277 males. Thus hunting probably i8 not a factor
