The Réunion night heron (Nycticorax duboisi) is an extinct species of heron formerly occurring on the Mascarene island of Réunion. It was for a long time only known from a single description, that of Dubois published in 1674. He stated: Bitterns or Great Egrets, large as capons, but very fat and good. They have grey plumage, each feather spotted with white, the neck and beak like a Heron, and the feet green, made like the feet of Poullets d'Inde (Porphyrio, W.R.). This bird lives on fish.
