The present study was conducted to investigate the prevalence of helminthic parasites of gastrointestinal tract (GIT) and its effect on blood picture in the captured migratory sparrows (Aluda arvensis). The parasitized sparrows were treated with a broad-spectrum anthelmintic i.e., panacur containing fenbendazole. On the basis of the cloacal swab samples seen under microscope, a prevalence rate of 56% (n=112) among all the two hundred migratory sparrows was observed. Half of these positive birds (n=56) in number were necropsied in order to recover the live parasites from the gastrointestinal tract. Live Heterakis gallinae and Ascaridia galli were recovered from 50% and 32% of the birds, respectively and 18% birds showed live mixed infection of both the parasites. None of the birds was parasitized with live trematode and/or cestode. The hematology revealed that total erythrocyte count, hemoglobin, lymphocytes and eosinophils were decreased and total leucocytic count was increased. From the remaining live, half of the parasitized birds i.e., 56 migratory sparrows, a treatment trial was conducted and an efficacy rate of 95% was observed 7 days post-medication.
