Aquatic organisms absorb the pollutants directly from water and indirectly from food chains. Heavy metals levels were determined in different organs of the wild birds (Anas crecca, Fulica atra, Larus genii, Egretta garzetta and Ceryle rudis) by using Atomic Absorption spectrophotometer. The samples collected from Lake Quaron which suffers from a serious pollution problems. The results revealed that heavy metal levels in Larus genii , Anas crecca and Egretta garzetta found to have their highest concentration in liver while Fulica atra and Ceryle rudis were in feather. The lowest heavy metals concentration found in all birds in muscles. 
The evaluated wild birds considers as an important bioindicator for the degree of pollution in aquatic ecosystems.
