During fall 1974, approximately 1,000 to 1,500 common crows (Corvus brachynhvnchos) died of aspergillosis in south-central Nebraska. The binds were debilitated, lethargic and dyspneic. On necropsy, typical lesions of aspergillosis were found in the lungs and air sacs. Histopathologic examination revealed granulomatous lesions around fungal hyphae in the respiratory system.
