In September 1960, the alimentary tracts and tracheas of 10 partridges from Ciechanów region (Warsaw voivodeship) were examined. The hunting grounds the birds derive from are marshy and covered with numerous shallow water pools. Six partridges showed the presence of 6 species of parasites, 3 of them - Prosthogonimus ovatus (Rud., 1803), Ascaridia galli (Schrank, 1788) and Capillaria obsignata Madsen, 1945 being found in this country for the first time in partridges.
