Opisthocomus hoazin (Statius Muller, 1776)

Le hoazin huppé ou hoazin (Opisthocomus hoazin), aussi appelé hoatzin ou sassa (en créole guyanais), est une espèce d’oiseaux tropicaux que l’on rencontre en Amérique du Sud, dans les marais du bassin amazonien et du bassin de l'Orénoque. C'est la seule espèce du genre Opisthocomus de la famille des Opisthocomidae et de l'ordre des Opisthocomiformes, ce qui en fait une espèce originale à de nombreux égards.
