Chronic regurgitation in a cockatiel (Nymphicus hollandicus) with a trichobezoar.

Crop disorders are very common in small psittacine birds. Psittacine birds are very curious and like chewing on different materials. Therefore, they are predisposed to ingest foreign material. In the literature only very few cases have been reported. This case report describes the clinical examination, the diagnostic workup and the ingluviotomy in a cockatiel with a bezoar in the crop.
