Herring gulls

Birds. In avian populations, organochlorine-associated suppression of T-cell mediated immune response has been found in herring gull and Caspian tern colonies adjacent to the Great Lakes in Northern America.In the most severe cases, immune response was suppressed by up to 50%. Similarly, seabirds exposed to petrochemicals from oil spills have been found to have suppressed immune function. " ...

Because of its high toxicity, there is concern about very low levels of 2,3,7,8-TCDD in biota. This raises analytical problems, and high resolution capillary gas chromatography (GC) is needed to obtain reliable isomer-specific analyses at low concentrations.
