Resumo(s)
Ocean contamination, particularly from persistent organic pollutants (POPs), remains a significant threat to
marine predators that occupy high trophic positions. Long-lived procellariform seabirds are apex predators in
marine ecosystems and tend to accumulate contaminants. Prolonged exposure to pollutants negatively affects
their fitness including reproductive success. Low breeding success may represent a hurdle for the restoration of
small and endangered seabird populations, including several highly threatened gadfly petrels. Here we investigated the annual variation (2019 and 2022) in organochlorine pesticide (OCP), polychlorinated biphenyl ether
(PCB), polybrominated diphenyl ether (PBDE), and polycyclic aromatic hydrocarbon (PAH) exposure in the
endangered Bermuda petrel (Pterodroma cahow), and the relationship between female contaminant burden and
breeding parameters. We found that petrels were exposed to a wide range of pollutants (33 out of 55 showed
