Abstract

Variation in metal contamination in six species of birds, namely the Cormorant (Phalacrocorax carbo), Cattle Egret (Bubulcus ibis), Little Egret (Egretta garzetta), Pond Heron (Ardeola grayii), Common Myna (Acridotheres tristis) and Jungle Babbler (Turdoides striatus) in Nilgiris district, Tamil Nadu, India. The accumulation of heavy metals differed among the species studied. On an average, Little Egret accumulated high concentrations of copper (53.31±23.19ppm) followed by Cattle Egret (16.27±9.83ppm) in liver. Of all the species, Jungle Babbler recorded the maximum concentrations (20.59±9.07ppm) in muscle. The Pond Heron recorded the maximum concentration (35.38±11.14ppm) in brain. On an average the maximum level was in the kidney of Common Myna (7.76±1.80ppm).
