Pentosidine levels cannot be used to age a long-lived seabird
Robust measurements of age are important for investigating ecological processes. In particular, seabirds, which form a major part of the coastal and marine ecosystems, may use and respond to their environment differently based on their age. This study aimed to determine whether pentosidine, a biolog...

Robust measurements of age are important for investigating ecological processes. In particular, seabirds, which form a major part of the coastal and marine ecosystems, may use and respond to their environment differently based on their age. This study aimed to determine whether pentosidine, a biological marker of age which was previously reliably used to age other avian species, could be used to age Bridled Terns (Onychoprion anaethetus) breeding on Penguin Island, Western Australia. It was found that patagial skin collagen-bound pentosidine cannot be used to determine the age of Bridled Terns because of low collagen levels in skin samples and that, overall, there was a low recapture rate of birds born on the island (less than 5% of the birds trapped in this study).
