The black bishop (Euplectes gierowii) is a species of passerine bird in the family Ploceidae native to Africa south of the Sahara. Three subspecies are recognised. The black bishop was first described by the German ornithologist Jean Cabanis in 1880 and named after H. Gierow, a Swedish explorer and collector in Angola. It is sometimes placed with E. aureus and E. hordeaceus in a separate genus, Groteiplectes.
A study of the molecular phylogeny of bishops and widowbirds published in 2008 found that it formed part of a clade along with the fire-fronted bishop (E. diadematus), black-winged red bishop (E. hordeaceus), northern red bishop (E. franciscanus), southern red bishop (E. orix), Zanzibar red bishop (E. nigroventris) and red-collared widowbird (E. ardens). An alternate common name is Gierow's bishop.

Rare
Under 5% of wildlife watchers report a Black Bishop sighting in Murchison Falls National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 293rd most-seen of the 424 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black Bishop in Murchison Falls National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black Bishop sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 10
Of the 10 parks where we can rate Black Bishop sightings, Murchison Falls National Park ranks 8th at under 5%. The best odds are in Lake Manyara National Park (Tanzania, about 40%), Kibale National Park (Uganda, about 10%) and Ngorongoro Conservation Area (Tanzania, about 10%).
Same genus: Euplectes
The closest relatives of the Black Bishop that you can see in Murchison Falls National Park (genus Euplectes, Bishops and Widowbirds) are Orange Bishop (about 40%) and Black-winged Bishop (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Bishop is recorded against all the birds logged in Murchison Falls National Park (20 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.
