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.
The white-backed night heron is 50–55 cm (20–22 in) in length with a black head and a short crest, or prominent feather display on the top of its head. The heron has large red eyes with white-ringed markings around them, and the lores, or the region behind the eye, are a pale yellow...

Rare
Under 5% of wildlife watchers report a White-Backed Night-Heron sighting in Mole National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 255th most-seen of the 266 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a White-Backed Night-Heron in Mole National Park on a given day, against under 5% in February–June and August–December, the lowest months. That is one of Mole National Park's driest months, with almost no rain against 220 mm in August. July has too few records to rate.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most White-Backed Night-Heron sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
9th of 10
Of the 10 parks where we can rate White-Backed Night-Heron sightings, Mole National Park ranks 9th at under 5%. The best odds are in Lake Mburo National Park (Uganda, about 20%), Liwonde National Park (Malawi, about 10%) and Niokolo-Koba National Park (Senegal, about 10%).
Same family: Ardeidae
The closest relatives of the White-Backed Night-Heron that you can see in Mole National Park (family Ardeidae, Herons, Egrets, and Bitterns) are Cattle Egret (about 50%), Grey Heron (about 50%) and Squacco Heron (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-Backed Night-Heron is recorded against all the birds logged in Mole National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
