The objective of this study was to collect some morphometric, hematological and heavy metals data on Passer domestics. For this study, 20 samples (10 male, 10 female) were collected from the wetlands of District Okara, Punjab, Pakistan. The size of the beak, tail, body length and chest circumference were all found to differ significantly between the sexes. Hematological parameters showed no significant variations between the sexes. The gut of the Passer domestics reveals that it eats largely grains and insects. The feeding preferences of male and female are identical. Atomic Inductively Coupled Plasma Spectrophotometer was used to determine heavy metals level in various body organs. Five heavy metals including Zinc (Zn), Chromium (Cr), Cadmium (Cd), Iron (Fe), Nickle (Ni) were detected in muscles, liver and kidney.
