Suspected osteoma in an eclectus parrot (Eclectus roratus roratus).

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.
