NOTE: Wing surveys were conducted in the Mississippi Flyway in 1959-60, in the Mississippi,and Atlantic Flyways 
i in 1960-61, and in all flyways in 1961-62 and 1962-63. 
Ratio not shown if based on less than 20 wings. 
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.
