Summary

This study was conducted to determine the influence of residues of organochlorine pollutants on reproductive success in the brown pelican. A sample egg was taken from each of 93 marked nests in the nesting colony in South Carolina. Periodic visits were made to determine the fate of marked nests. Each sample egg was analysed for residues of organochlorine pollutants. Nest success in the brown pelican was related to residues of DDE and dieldrin in sample eggs. DDE seemed primarily responsible for nest failure; however, deleterious effects of this pollutant on nest success were not satisfactorily separated from those induced by dieldrin. Significant intercorrelation of all five organochlorine residues identified in the eggs complicated [...]
