An approximately 10-yr-old, captive-born female toco toucan (Ramphastos toco) was presented due to an acute onset of depression and apathy. On visual and physical examination, it showed an abnormal posture and dehydration, respectively. Serum biochemistry revealed hyperuricemia (39.4 mg/dl) and elevated glutamic oxaloacetic transaminase (GOT; 1,050 U/L). Radiographs demonstrated an enlargement of the cardiac silhouette. The bird died 7 days after presentation, despite treatment with enrofloxacin, allopurinol, a preparation of hepatorenal protectors, and complex B vitamins with dextrose. Necropsy revealed severe fibrinohemorrhagic pericarditis with a 15 mm long and 2.5 mm diameter, rigid foreign body in the pericardial exudate. Microscopically, this foreign body was of vegetal origin.
