A female slaty-backed gull (Larus schistisagus) died suddenly without apparent clinical signs. At necropsy, well demarcated 7 to 10 mm yellow to white nodules were presented at the lungs and thoracic cavity. Microscopically, multifocal necrotic granulomas were observed in the lung tissue and amorphous acidophilic fibrin were accumulated in the granuloma and normal alveolar space. Periodic acid-Schiff (PAS) staining demonstrated numerous pinkish red branched hyphae embedded in the center of these granulomas. According to fungal culture using Sabouraud's dextrose agar plate, Aspergillus fumigatus was isolated from lung lesions. This is the first report for pulmonary aspergillosis of wild slaty-backed gull in Korea.

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.
