Range DescriptionRunion Night-heron Nycticorax duboisi was endemic to Runion (to France), and is known only from an incomplete tibiotarsus collected by Bertrand Kervazo in the Grottes des Premiers Franais in 1974. The only historical record of the species is Dubois' (1674) description of "bitterns or great egrets, large as big capons, but fat and good. They have grey plumage, each feather tipped with white, the neck and beak like a heron and the feet green, made like the feet of the "Poullets d'Inde". The specimens are deposited in the Musum National d'Histoire Naturelle, Paris (Cowles 1994).
