Study of mensural parameters, hematology, food preferences and level of different heavy metals in house sparrow (Passer domestics) from grasslands of Punjab, Pakistan

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.
