A Grey parrot and a Yellow-crowned Amazon were presented with severe respiratory distress and weight loss, and collapse and melena, respectively. Despite supportive therapy, both parrots quickly succumbed and died, with no ante-mortem diagnosis made. Postmortem examinations yielded a diagnosis of a follicular and papillary form of thyroid adenocarcinoma. Although thyroid neoplasia has been reported in birds, these two cases are the first described thyroid neoplasia in these parrot species and the first reported papillary form of thyroid adenocarcinoma in birds.
