Survival rate = G1:2% 
Standard error = ev 
95% confidence interval = 22.0-40.4 
Mortality rate = 68.8% 

The immature survival rate for this period was 25% 
(Table 14). 
Hunting Mortality 
For adult doves, mortality attributable to hunting was 
computed as 18% of total mortality; for immatures, the 
figure was 19% (Table 15). Hunting caused about 20% of 
adult male mortality and 14% of adult female mortality 
(P < 0.05), 
Productivity Needed to Maintain 
a Stable Population 
Productivity required to maintain a stable population was 
estimated by using the survival rates from Tables 11 and 
14, Considering the entire period, 2.3 young produced per 
adult were required to maintain a stable population 
(Table 16).
