Ansorge's greenbul (Eurillas ansorgei) or Ansorge's bulbul, is a species of the bulbul family of passerine birds. It is found in western and central Africa. Its natural habitat is subtropical or tropical moist lowland forests.
Ansorge's greenbul was originally described in the genus Andropadus and was re-classified to the genus Eurillas in 2010. Alternatively, some authorities classify Ansorge's greenbul in the genus Pycnonotus. Some authorities have considered Ansorge's greenbul as a subspecies of the little grey greenbul. The common name and scientific name commemorate the British explorer and collector William John Ansorge who collected natural history specimens in Africa.

Possible
About 20% of wildlife watchers report an Ansorge's Greenbul sighting in Bwindi Impenetrable National Park on a given day, based on 319 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 89th most-seen of the 400 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June–September and November–December
In those months about 20% of wildlife watchers report an Ansorge's Greenbul in Bwindi Impenetrable National Park on a given day, against about 10% in January–May and October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ansorge's Greenbul sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Bwindi Impenetrable National Park, in our data
Bwindi Impenetrable National Park is the only park on Wallace's Line with enough records to rate Ansorge's Greenbul sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Eurillas

GBIF citizen-science records
It is estimated from how often the Ansorge's Greenbul is recorded against all the birds logged in Bwindi Impenetrable National Park (319 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.
