Los Angeles Times article. According to California scientists, some Forster’s tern colonies have reproduction success rates as low as 7%, posing a serious threat to their survival. It is unclear, however, how much of this difficulty is due to PBDEs; these birds also carry high concentrations of mercury and PCBs.
