title: Cloacolith in a blue-fronted amazon parrot (Amazona aestiva).
abstract: A 4-year-old blue-fronted Amazon parrot (Amazona aestiva) was admitted for vocalization secondary to constipation. Saline infusion cloacoscopy revealed the presence of a 2-cm-diameter cloacolith within the coprodeum that was obstructing the rectal opening. The cloacolith was fragmented with a pair of biopsy forceps and the pieces removed. The cloacolith was subsequently analyzed and was composed of 100% uric acid salts. The bird improved completely and was able to defecate normally after the procedure. Cloacoliths are relative uncommon cloacal conditions, and this case documents cloacoscopic findings, rectal obstruction, and confirmation of its uric acid composition by urolith analysis.
