Parus Major Rock Wren Animal Bird

Parus Major Rock Wren Animal Bird

Metal accumulation in three passerine bird species, Great Tit Parus major, Rock Bunting Emberiza cia, and Blackbird Turdus merula, was analyzed in a polluted zone where there is a coal-fired power plant Cercs, Northeast Spain, and a non-polluted zone located 40 km from the source of pollution. Rainwater from the polluted area was acidic (pH 5.2) but the calcareous composition of the soil in this zone buffered the soil and water pools; there were no significant differences between soil pH in the two areas. Metal accumulation in organs and tissues was dependent upon the species and the diet.
