A 12-year-old female cockatiel (Nymphicus hollandicus) presented with a history of acute onset dyspnea. Clinical signs were not evident initially, and survey radiographs were unremarkable. Dyspnea returned 12 hours later and was accompanied by audible wheezing, suggesting tracheal obstruction. An air sac cannula was placed to allow adequate ventilation. Tracheoscopy with a 1.2-mm semirigid telescope revealed a seed foreign body in the trachea proximal to the syrinx. The semirigid telescope allowed visibility of the seed during removal with endoscope graspers. Initial attempts at removal failed, but removal was successful 36 hours later during a second attempt. The bird recovered uneventfully and remains clinically normal 1 year after removal of the obstruction.
