The purpose of the work was determination of extensiveness and intensity of invasion of intestinal parasites in racing pigeons from the south of Poland including the size of flocks. The material for study included 70 collective samples of faeces. During the research the presence of Eimeria sp. in 65.7% of cases, Ascaridia sp. in 10% of the samples and Capilaria sp. in 17.14% of the samples was stated. The results confirm domination of low intensity of the invasion of Eimeria (below 1 thousand oocytes in 1 gram of faeces in 41.4% of the samples, 1–5 thousand oocytes in 1 gram of faeces in 17.2% of the samples, over 5 thousand oocytes in 1 gram of faeces in 7.2% of the samples). Intensity of invasion of nematoda was low and did not exceed 500 eggs in 1 gram of faeces.
