摘要: We assessed heavy metal concentrations in feathers of 38 Kagus Rhynochetos jubatus living on ultramafic soils New Caledonia. Concentrations metals down were similar to shafts primary or secondary feathers, whereas the vanes much higher, indicating that not due external contamination but rather ingestion. Although there was no anthropogenic pollution our study area, iron (Fe), zinc (Zn), manganese (Mn), chromium (Cr), selenium (Se), strontium (Sr) and cobalt (Co) 1.2–21 times higher Kagu than average other bird species studied, majority those from polluted environments. may have specific adaptations enable them live environments with naturally high concentrations.
