摘要: To circumvent difficulties associated with monitoring adult predatory birds, we investigated the feasibility of different non-destructive strategies for nestling white-tailed eagles (Haliaeetus albicilla). We were able to quantify polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and organochlorinated pesticides (OCPs) in body feathers (16.92, 3.37 7.81 ng g− 1 dw, respectively), blood plasma (8.37, 0.32 5.22 mL− ww, preen oil (1157.95, 30.92 440.74 respectively) all nestlings (N = 14). Strong significant correlations between concentrations (0.565 ≤ r 0.801; P < 0.05) indicate that levels closely reflect internal state contamination. found fewer feather concentrations, which almost exclusively PCB (0.554 0.737; 0.05). These results differ from a previous study on younger nestlings, may studied here, ready fledge nest, possibly undergoing certain physiological changes have confounded use as biomonitor matrix. Finally, provide an integrated discussion birds.
