The yellow bishop (Euplectes capensis), also known as Cape bishop, Cape widow or yellow-rumped widow, is a resident breeding Afromontane bird species. This common weaver occurs in less arid vegetated areas, such as fynbos, moist grassland and bracken-covered valleys at altitudes from sea level to the Ethiopian Highlands.
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the yellow bishop in his Ornithologie based on a specimen collected from the Cape of Good Hope. He used the French name Le pinçon du Cap de Bonne Espérance and the Latin Fringilla Capitis Bonae Spei. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the yellow bishop. Linnaeus included a brief description, coined the binomial name Loxia capensis and cited Brisson's work. The specific name capensis denotes the Cape of Good Hope. This species is now placed in the genus Euplectes... Wikipedia →
With luck
About 10% of wildlife watchers report a Yellow-rumped Widowbird sighting in Dar es-Salaam on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January, May–June and October
In those months about 20% of wildlife watchers report a Yellow-rumped Widowbird in Dar es-Salaam on a given day, against about 10% in February–April, July–September and November–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-rumped Widowbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 cities where we can rate Yellow-rumped Widowbird sightings, Dar es-Salaam has the highest daily chance: about 10%. Next come Harare (Zimbabwe, about 10%) and Cape Town (South Africa, under 5%).
GBIF citizen-science records
It is estimated from how often the Yellow-rumped Widowbird is recorded against all the birds logged in Dar es-Salaam (19 verified sightings), 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.
