The proventriculus:keel ratio was evaluated as a prognostic indicator for short‐term survival in parrots with proventricular disease. Measurements were made from right lateral radiographs of 41 parrots with proventricular disease. Results were compared with the previously described abnormal proventriculus:keel ratio range and to short‐term clinical outcome at 1‐month postdiagnosis. The ratio in all parrots was >0.52, and 39% of parrots succumbed to their disease within 1 month of diagnosis. There was no significant association between the proventriculus:keel ratio and survival duration (P=0.9). The proventriculus:keel ratio is a sensitive indicator of proventricular disease in parrots but is insensitive as a prognostic indicator.
