Predominance of BDE-209 and other higher brominated diphenyl ethers in eggs of white stork (Ciconia ciconia) colonies from Spain

► Higher brominated BDEs dominate the congener profiles in eggs of white stork. ► Evidence for BDE-209 environmental debromination in white stork eggs. ► Evidence for BDE-209 bioavailability and bioaccumulation in eggs from terrestrial species.
