<div style="text-align: justify;">Out of around 200 pigeons (housed at Mahendra Chaudhury Zoological Park, Chhatbir, Punjab), two pigeons exhibiting signs of depression, lethargy, droopiness and blood tinged greenish diarrhoea were quarantined for detailed examination. The faecal examination revealed a concurrent parasitic egg load of capillarid, ascarid and strongyle eggs. Morphological observations after clearing of retrieved parasites from the deceased pigeons revealed the presence of Ascaridia columbae, Capillaria obsignata, and Ornithostrongylus quadriradiatus. Histopathological studies of the intestines revealed sloughing and hyperplasia of the lining epithelium; whereas kidneys of one of the pigeon exhibited the extensive tubular damage and marked haemorrhages with cut sections of the parasite, Paratanaisia bragai. The other vital organs showed no signs of any significant lesions in both pigeons. This seems to be the first report of fatal concurrent gastrointestinal and renal pathology due to A. columbae, C. obsignata, O. quadriradiatus and P. bragai in pigeons kept at zoological park in India.</div>
