Population justification
No population remains.

Distribution and population

Nycticorax mauritianus was described from seven fossil bones (of which only a coracoid and a tarsometatarsus are available today), from Mauritius (Cowles 1987). Leguat's description of great flights of bitterns in 1693 probably refers to this species, given that the only two other species of Ardeidae known from the island are Dimorphic Egret Egretta dimorpha and Green Heron Butorides striatus (Cheke 1987), species which could in no way be described as bitterns.


It is likely to have inhabited freshwater wetlands.


Hunting is likely to have led to its extinction.
