ResumoIn a sample of 269 Common Gulls collected on the west coast of Norway (Agdenes 63°35'N, 9°45'E), 11 different cestode species from three orders were recovered: Anomotaenia micracantha, Choanotaenia larimarina, Dilepis undula, Paricterotaenia porosa, Hymenolepis cirrosa, H. ductilis, H. lateralis, Diphyllobothrium dendriticum, D. ditremum (plerocercoids), Schistocephalus solidus, and Tetrabothrius sp. Ecoparasitological information for the different species is presented based on prevalence and mean intensity in relation to locality, sex, age and intestinal site preference. Different species were found to have their main occurrence at different sites in the alimentary canal. The species' seasonal dynamics in the Common Gulls is described. Variation in the bird infection parameters appeared to be controlled mainly by transmission related events, the availability of infective larvae and host feeding behaviour.
