Birds of pray constitute a special group of animals. They are exposed to contact with a number of, often sick, victims. Moreover, they cumulate some toxic compounds present in their victims’ bodies. Therefore, they are closely studied by ecologists and veterinarians. Literature data and our own experience show that birds in captivity often suffer from trichomonosis with characteristic nodular necrotic-inflammatory lesions in the beak cavity. This is most common in young birds fed with pigeon meat. Other significant health problems are tuberculosis, colibacteriosis and aspergillosis, but these are rarely found in the natural environment. Wild birds of pray commonly suffer from parasitic infestations caused by Trichomonas and coccidia, such as Caryospora and Eimeria, as well as Sarcosystis, Frankelia and Toxoplasma. Virus infections are mainly caused by herpesviruses and paramyxovirus PMV-1.
