Continental United States weighted ratio3-- 
NOTE: Wing surveys were conducted in the Mississippi Flyway in 1959- -60, in the Mississippi and Atlantic Fly- 
ways in 1960-61, and in all flyways in 1961-62 and 1962-63. 
1 R-East, W-west of the Continental Divide. 
2 Ratio not shown if based on less than 20 wings. 
3 In estimating flyway and U.S. ratios, the ratio for each State was weighted in proportion to the estimated 
size of the kill in that State.
