Blood films and sera samples from wild Oklahoma raptors (Strigiformes —36 birds, 3 species; Falconiformes—50 birds, 7 species) were examined for hematozoa and tested for serologic antibody response to Newcastle Disease Virus (NDV), encephalitis (EEE and WEE), ornithosis, and influenza. Twenty-nine of 36 (80.5%) Strigiformes and 24 of 50 (48.0%) Falconiformes showed the presence of one or more hematozoa. Serologic testing revealed the serum of one adult male red-tailed hawk positive for antibody to NDV and one additional adult male red-tailed hawk positive for antibody to type-A influenza.
