Blood parasites often incur a substantial fitness cost to the infected individuals, sometimes resulting in death of the host. Some bird species, however, are apparently free of blood parasites, presumably due to the lack of exposure to blood parasite vectors. Protective immunity may be also responsible for the absence of infections by haematozoa. In this study, we tested the presence of blood parasites in Common Gulls (Larus canus) and Black-headed Gulls (Chroicocephalus ridibundus) nesting in… CONTINUE READING
