The present study assessed heavy metals content in the eggs of the (house sparrows (Passer domesticus) and laughing dove (Spilopelia senegalensis) to give baseline data about metals concentration in two species from urban environments in the Basrah city(south of Iraq). The house sparrow is strappingly connected with human surroundings, and be able to live in urban or rural locations. Laughing dove live successfully in the urban environment . Although, it is one of the great inhabitants of the avian world. However, using common species with broad allocations prevents disagreeable effects on an endangered species population and may permit comparing concentrations of metals gathering between different environments. Concentrations of pb and cr in eggs of the birds were determined using Atomic Absorption spectrometry. Result established that eggshell in two birds species were collected high concentrations of lead metal arrived at (25.6,18.6ug/g) respectively, while, egg content was accumulate lowest level of lead ranged between (3.5 ug/g )and (2.5ug/g), respectively . Conversely, level of chromium was low in eggshell and egg content of two birds species. Positive relationships were observed between pb and cr level in eggshell and egg content in house sparrow.
