In this study, we examined the levels of POPs and PBDEs in tail feathers, serum and the preen gland of magpies (Pica pica). High and significant correlations (Spearman rank correlation coefficient (rs) up to 0.9 and p < 0.001) were established between concentrations of selected organic pollutants in tail feathers and concentrations in the preen gland of magpies. Correlations of feathers and serum were only significant for the higher chlorinated PCB congeners. The results of this study suggest that preening feathers with oil from the uropygial gland could have an important impact on concentrations of organic compounds measured in the feathers.
