The present study investigated inter- and intraindividual variation of the stress response (in terms of plasma levels of corticosterone) to handling in birds. Individual captive great tits (Parus major) were exposed to a standardised capture and handling protocol three times at about 2-week intervals. Mean plasma corticosterone levels were low (<5 ng/ml) when the birds were first sampled and increased in all birds 10 min after handling (mean levels on each sampling occasion 14 to 22 ng/ml… CONTINUE READING
