Corticosterone responses of hand-reared and parent-reared grey-faced petrel chicks (Pterodroma macroptera gouldi)

Abstract 10.1002/zoo.20047.abs Hand-reared grey-faced petrel (Pterodroma macroptera gouldi) chicks (Order Procellariformes) that were subjected to a standardised blood sampling protocol immediately before they fledged showed a reduced corticosterone response compared to parent-raised chicks. Serum corticosterone concentrations were lower in hand-reared than parent-reared birds 30 and 60 min after handling was initiated (21.5±6.7 vs. 105.4±7.4 ng/ml […]
