The feeding habits of House Crow indicated that it is an omnivorous bird. The fresh and dry excreta of House Crow was collected from its roosting, foraging and nesting sites. The mean weight of excreta was 0.146 ± 0.14 g/ pellet and it was semisolid varied from grey to brown in colour. Parasitological examination of excreta of House Crow showed the prevalence of two parasite species, strongyle eggs (38.09%) and cestode (4.76%). The cestode was present in sample from agri field area only and srtongyle eggs were observed in samples from both agri field and residential areas. The heavy metal analysis in excreta of House Crow included As, B, Ca, Cd, Cr, Co, Fe, K, Mg, Mn, Na, Ni, P, Pb, S and Zn. In which As, B, Cd and Pb are included in category of heavy metals. The levels of As, B and Pb were above the normal range but below the toxic range reported for body tissues of birds. OPs, OCs and synthetic pyetheroid pesticide residues were analyzed in House Crow excreta. Pesticide residues were found to be absent in excreta samples of House Crow.ennullThesis
