Technical Abstract: Neoplasms of respiratory tract are rare in birds. This report describes carcinoma of the bronchial epithelium in a Red Shouldered Hawk (Buteo lineatus). Grossly, the caudal air sac and coelomic cavity contained approximately 15 ml of dark brown cloudy fluid that displaced the intestines cranially. Nodular plaques were present on the viscera and air sacs. The caudal aspect of both lungs were mottled pale to dark. Histologically, the mass expanded the bronchial lumen and was composed of papillary proliferations of rows of small cuboidal epithelial cells that were small and uniform in size with a low mitotic index.
