A flightless brown hawk owl (Ninox scutulata) weighing 180 g was rescued and referred to the teaching veterinary hospital with humerus open fracture. On physical examination and radiography, open fracture of the left humerus was found. After 3 days, orthopedic surgery was operated with intramedullary pins and wires. The bird died 2 days after surgery with anorexia. On necropsy, multiple green nodules with 2-3 mm in diameter were observed at the surface and inside of the left lung. Numerous conidial heads and spores were seen in the center of foci in the histopathological examination. The mycelia penetrated the surrounding pulmonary parenchyma, showing inflammation and necrosis. The fungus was isolated from the lung and cultured on Sabouraud Dextrose Agar at $30^{\circ}C$ for 7 days. The colony was blue-green color with a powdery surface. The fungus was identified as Aspergillus fumigatus by DNA analysis, including the internal transcribed spacer region, partial ${\beta}$-tubulin, and the calmodulin gene. This case was diagnosed as pulmonary aspergillosis secondary to open fracture of pneumatic bone in a brown hawk owl.

Wild owls are widespread in Korea, even being common in urban areas due to the presence of hills or small mountains in and around the cities. This results in high levels of contact between owls and domestic animals. This study investigated the prevalence of avian hematozoan parasite infection in 2 common owl species in Chungbuk province of Republic of Korea for 3-year period: the Eurasian eagle owl (Bubo bubo) and the Brown hawk owl (Ninox scutulata). Peripheral blood smears taken from 56 wild owls were examined by microscopic examination and confirmed by molecular technique. Twenty (36%) of these samples tested positive for the Haemoproteus infection. The infection rate was higher in Brown hawk owls (50%) than in Eurasian eagle owls (33%). These results indicate that the wild owls may act as a reservoir for Haemoproteus infection in susceptible domestic birds.
