The black-headed weaver (Ploceus melanocephalus), also known as yellow-backed weaver, is a species of bird in the family Ploceidae. It is a resident breeder in damp areas in tropical Africa. The black-headed weaver was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Loxia melanocephala. He specified the type locality as Guinea. Linnaeus based his account on the "Gamboa Groasbeak" that had been described and illustrated in 1750 by the English naturalist Eleazar Albin in his book A Natural History of Birds. Albin had sketched a live specimen belonging to the Duke of Chandos at his country house, Cannons, which was located about 11 mi (18 km) northwest of London near Edgware. The specific epithet melanocephalus, melanocephala combines the Ancient Greek μελας/melas, μελανος/melanos meaning "black" with -κεφαλος/-kephalos meaning "-headed". The black-headed weaver is now one of 67 species placed in the genus Ploceus that was introduced in 1816 by the French naturalist Georges Cuvier.

With luck
About 10% of wildlife watchers report a Black-headed Weaver sighting in Semuliki National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 170th most-seen of the 280 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Black-headed Weaver in Semuliki National Park on a given day, against under 5% in February–March, June–July and September–December, the lowest months. That is one of Semuliki National Park's wettest months, with about 120 mm of rain against 5 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-headed Weaver sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 13
Of the 13 parks where we can rate Black-headed Weaver sightings, Semuliki National Park ranks 10th at about 10%. The best odds are in Queen Elizabeth National Park (Uganda, about 40%), Murchison Falls National Park (Uganda, about 30%) and Kibale National Park (Uganda, about 20%). All parks ranked.
Same genus: Ploceus
The closest relatives of the Black-headed Weaver that you can see in Semuliki National Park (genus Ploceus, Typical Weavers) are Vieillot's Weaver (about 20%), Village Weaver (about 20%) and Black-necked Weaver (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-headed Weaver is recorded against all the birds logged in Semuliki National Park (22 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.
