As there is no data available on parasite infection of pigeons (Columba livia) in the region, the present study was carried out on domestic pigeons in Mashhad city in the north-east of Iran. Three hundred specimens were examined for the presence of ecto and endoparasites. A total of 300 pigeons, %21.6(n=65) and %15.3(n=46) were infected with nematodes and cestodes respectively whereas no trematodes were found. The helminths and their prevalence were Nematoda: Ascaridia columbae (20.37%), Capillaria bursata (3.7%), Capillaria caudinfillata (1.85%), Eulimdana clava (2.7%), Gongylonema spp (0.9), Cestoda: Choanotaenia infundibulum (11.11%), Raillietina echinobothrida (6.48%). Six different species of ectoparasites: Columbicloa columbae (42.8%), Pseudolynchia canariensis (16.1%), Menocanthus stramineus (10.7%), Menopon gallinae (7.1%), Lipeurus caponis (5.3%), Argas reflexus (3.5%) and 2 haemoparasites species Haemoproteus columbae (50%) and Leucocytozoon spp. (2%) were identified. Further studies are recommended in assessing the effects of the parasites on the pigeons’ health and production.
