Biting lice were collected (mostly in Poland) from 15 species of Charadriiformes (Charadriidae, Scolopacidae, Laridae and Alcidae). We tried to determine the frequency of occurrence of particular species of Mallophaga. Quantitative and qualitative analysis of co-occurrence of external parasites (Mallophaga and some Astigmata) was also carried out. We stated that inter-species competition is not significant in shaping the fauna of external parasites of Charadriiformes.
Examination of 10 bird species of the family Charadriidae have revealed the following nematode species: Strongyloides turkmenicus, Syngamus palustris, S. trachea, Porrocaecum semiteres, Tetrameres dubia, Eucoleus contortus and Capillaria sp. Three of them: S. turkmenicus, S. palustris and T. dubia parasitizing those hosts were found the first time in Czechoslovakia. Tringa glareola was found a new host for S. palustris.
