Abstract:This study aimed to determine the levels of heavy metals in birds' feathers and blood. In the study, ten (10) individual bird samples were collected using mist nets between 6:00 to 9:00 am within the forest of Elizade University and analyzed by Atomic Absorption Spectrophotometer (AAS) for metal analysis. Cadmium, lead, and iron had higher concentrations than WHO guidelines in both feathers and blood. Essential metals such as copper, zinc, and iron were found in higher concentrations than non-essential metals like lead and cadmium in both feathers and blood. A similar pattern of metal concentrations was detected in both blood and feathers (Zn>Fe>Cu>Pb>Cd) — Lonchura bicolor and Lonchura cucullata exhibited the highest levels in blood and feathers, while Eurillas latirostris showed the lowest. Lonchura bicolor and Lonchura cucullata can be used as environmental bio-indicators within Elizade University. The levels of non-essential metals cadmium and lead should be regulated within Elizade University.
