Table 2.

Survival and recruitment (in parentheses) rates by logistic regression. The factors ‘birth year’ and ‘rearing colony’ were included as fixed effects in each model, to account for temporal and spatial variation in survival and recruitment. Sample sizes are 34 survivors (30 recruits) from 152 fledglings. p-values less than 0.05 are shown in italic.
