Visceral urate deposition (visceral gout) is a common finding during post-mortem examination of poultry. Rare cases of visceral gout may occur in wild birds. A rare case of visceral urate deposition in a little bittern (Ixobrychus minutus) is reported here. In May 2013, carcass of a little bittern was submitted for necropsy to the Clinic of Poultry Diseases (Faculty of Veterinary Medicine, Razi University) by local authorities of Iran Department of Environment. At necropsy, white chalky deposits were observed on the heart and thoracic air sacs of the bird. To confirm the presence of urates, chalky deposits were collected from pericardium and tested by muerxide test. Heart and kidneys were sampled, preserved in 10% neutral-buffered formalin solution and submitted to laboratory for histopathology. Murexide test was positive for presence of uric acid in chalky deposits collected from pericardium. Light microscopy of affected organs confirmed the condition as visceral urate deposition. To the best of our knowledge, this is the first report on the occurrence of visceral urate deposition in a little bittern.
