of banding, as determined by band recoveries.

*Corrected to compensate for time and place of banding: during the hunting season 
and halfway down the flyway. Not corrected to compensate for bands not reported. 
Of particular note is the finding that yearly variations in rate of mallard loss were 
somewhat similar at the two banding stations, about 175 miles apart. There was also simi- | 
larity in trends in the year-to-year percentage losses in the mallard, the black duck, and even 
in the early migrating blue-winged teal. 
The lowest rates of hunter-bag losses in mallards occurred in 1939, 1941, 1943, and 
1947. The highest were in 1940, 1942, 1944, 1945, and 1946. The bag in the period 1944-1947 
averaged-about 1.5 per cent more per year than it did in the period 1940-1943.
