Comparison of the Metal Concentrations in the Feathers of Three Bird Species from Southern Iran

This study was conducted to determine the concentration of metals, namely cadmium, lead, cobalt and copper, in the feathers of chukar (Alectoris chukar), see-see partridge (Ammoperdix griseogularis) and rock dove (Columba livia) in order to: examine the species, gender and age related variations in trace metal accumulation, and identify any relationships between species. Bird samples were collected in February 2012 from the Hormod protected area, southern Iran and the concentration of metals were measured using a Shimadzu AA 660 flame atomic absorption spectrophotometer. The concentrations in all three species were copper > lead > cadmium > cobalt. The average cadmium concentrations were 2.0, 1.9, and 1.9 mu g/g for A. chukar, A. griseogularis, and C. livia, respectively. The average lead concentrations were 8.0, 5.4, and 7.7 mu g/g for A. chukar, A. griseogularis, and C. livia, respectively. The results showed that in all three species, the highest metal concentrations were observed in female/adult birds and the lowest concentrations were found in female/juvenile birds (except lead in A. chukar and copper in C. livia).
