Feral pigeon (Columba livia) has been known as a good indicator for accumulations of chemical pollutants in urban areas. However, it is against the animal rights to kill the indicator species in order to monitor pollutants accumulations in wild birds. Eggs and feathers of birds, therefore, have been used as non-invasive monitoring materials. Even though eggs are a good indicator for accumulations of lipophilic pollutants, but unsuitable for some heavy metals such as lead and cadmium because bird’s ovary builds a sort of barrier to inhibit higher accumulations of some heavy metals in the eggs. Therefore, feathers instead of eggs have been used as a non-invasive indicator for accumulations of heavy metals. However, there are few studies of heavy metal accumulations of feral pigeon in Korea. In this study, we characterized the characteristics of heavy metal accumulations of feathers in relation to eggs, bloods, viscera and bones in feral pigeons between two sites (Hangang Park of urban area and Hampyeong Park of rural area). The concentrations of lead (Pb) in the blood, liver and bone were significantly different between Hangang Park (with higher Pb concentrations) of urban area and Hampyeong Park (with lower Pb concentrations) of rural area. The Pb concentration in the feathers was also significantly higher at Hangang Park than at Hampyeong Park. The correlations among the concentrations in the breast, wing and tail feathers, the blood, lung, liver, kidney and bone showed that the Pb concentrations in the feathers were significantly positively correlated with the levels in the kidney and bone. Overall, feathers of feral pigeon may be candidate for bioindicator to monitor for Pb accumulations in urban areas.
