A 7-month-old, male eclectus parrot (Eclectus roratus roratus) was presented with a slow-growing mass over the chest and localized self-trauma to the area. Repeated sternal trauma secondary to an improper wing trim was observed in this case before development of the lesion. Surgical excision of the mass was performed for diagnostic and treatment purposes. On histopathologic examination, the mass was characterized by well-differentiated trabecular bone surrounded by a thin layer of periosteum. These findings were consistent with, but not exclusive to, a diagnosis of osteoma. This benign bone lesion is rare in human and veterinary medicine, with even fewer reports of this condition in avian patients. Trauma to the sternum from falling because of wing clipping was the most likely inciting cause in this parrot.
