from 1959-61 in 10 States and Provinces was used for weight¬ 
ing. Kill estimates were provided "by State Conservation 
Departments and the Canadian Wildlife Service. Average 
kill for 3 years was used in an effort to minimize gross 
errors in annual estimates. 
Results 
Table 5 shows the ratios of immatures per adult female 
for States and Provinces from which 50 or more wings were 
received each year. Also shown are the ratios of immatures 
per adult (males and females combined). 
The number of immatures per adult female varied among 
States and Provinces each year (as did the number of imma¬ 
tures per adult). The number of immatures per adult female 
in the continent-wide kill, weighted by kill estimates, was 
1.8 in 1962 and 1963* Similarly, the number of immatures 
per adult was 1.1 in both years. 
These values indicate that woodcock productivity was 
identical in both 1962 and 1963* However, in 1963, the 
hunting season was closed in a number of eastern States 
because of fire hazard caused by dry conditions. For 
this reason, dates of hunting differed, and data gathered 
in the 2 years are not completely comparable. Furthermore, 
kill information used for weighting does not pertain to 
the same years,'and reliability of the estimates is not 
known. Therefore, woodcock productivity may have varied 
more than was apparent from the wing samples.
