About the White-Backed Night-Heron

The white-backed night heron (Calherodius leuconotus) is a species of medium-sized heron in the family Ardeidae, found in sub-Saharan Africa. The white-backed night heron was formally described in 1827 by the German naturalist Johann Wagler under the binomial name Ardea leuconotus. He specified the type locality as Senegambia. This species was formerly placed with the Japanese night heron and the Malayan night heron in the genus Gorsachius. Based on the results of a molecular genetic study published in 2023, it is now the only species placed in the resurrected genus Calherodius that had originally been introduced in 1855 by the French naturalist Charles Bonaparte. Bonaparte specified the type species as Ardea cucullata Lichtenstein which is now considered to be a junior synonym of Ardea leuconotus Wagler. The species is treated as monotypic: no subspecies are recognised.
