The prevalence and ecology of the haematozoan parasites of a rural population of European blackbirds, Turdus merula, were investigated. Parasites belonging to eight species from four genera (Leucocytozoon, Plasmodium, Haemoproteus, and Trypanosoma) were identified. Prevalence was high: 83% of adults and 80% of juveniles were infected by at least one species of haematozoa, but no parasites were detected in 8-day-old nestlings. There were no sex differences in infection rates and only Plasmodium infection varied with age among adult blackbirds. Haemoproteus infections increased and Plasmodium infections decreased through the sampling period (January to July), but infections with other haematozoa showed no seasonal change. Haemoproteus and Plasmodium were negatively associated with each other, even during the period when infections by both genera were frequent in the study population.
