ABSTRACT 
An index of size of the woodcock breeding population in 
1962 was obtained from a Singing Ground Survey conducted in 
20 eastern and central States and 4 eastern Canadian Provinces. 
East of the Appalachians, 148 routes run both in 1961 and in 
1962 were available for comparison. West of the mountains, 
115 comparable routes were covered. 
The population index showed a slight decrease in the east 
(-3 percent) and no change in the west. For the 2 regions com- 
bined, there was no significant change in size of the breeding 
population from 1961 to 1962 (index value, -2 percent). 
An index of woodcock reproductive success in 1960 and 1961 
was obtained from age ratios in the hunting kill as determined 
from wings. For both seasons combined, hunters contributed 
21,343 woodcock wings. 
Age ratios in the hunting kill varied among States and 
Provinces each year. For the combined kill, the ratio of 
immatures per adult female was 1.8 in 1960 and 1.9 in 1961. 
The ratio of immatures per adult male and female in the 
continent-wide kill was 1.1 in both years.
