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... Wikipedia →

With luck
About 10% of wildlife watchers report a White-Backed Night-Heron sighting in Nairobi National Park on a given day, based on 113 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 206th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the White-Backed Night-Heron is recorded against all the birds logged in Nairobi National Park (113 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.
