A 20-year-old male cockatiel (Nymphicus hollandicus) exhibiting dysphagia, regurgitation, and lethargy was diagnosed with invasive squamous cell carcinoma involving the crop. The neoplastic mass was closely associated with the right vagal nerve and was obstructing 80% of the crop lumen. Dysphagia appeared to be linked to nerve dysfunction resulting in ileus of the upper digestive tract. This is the first published report of squamous cell carcinoma in the crop of a psittacine species resulting in nerve dysfunction and possible vagal indigestion.
