Studies were made on the effect of a diet of 10 ppm of a polychlorinated biphenyl (Aroclor 1254) on the reproduction of ring doves. Embryonic mortality was greatly increased when the eggs were incubated by the parent birds and decreased by artificial incubation. Monitoring of egg temperature suggests that increased mortality was due to decreased parental attentiveness. This observation stresses the importance of using conditions that are similar to natural conditions in testing the effects of environmental contaminates on avian reproduction.
