The little grey greenbul (Eurillas gracilis) is a species of the bulbul family of passerine birds. It is widely distributed across the African tropical rainforest. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical swamps.
The little grey greenbul was originally described in the genus Andropadus and was re-classified to the genus Eurillas in 2010. Alternatively, some authorities classify the little greenbul in the genus Pycnonotus. Alternate names for the little grey greenbul include the grey greenbul and little grey bulbul.

GBIF citizen-science records
It is estimated from how often the Gray Greenbul is recorded against all the birds logged in Kakum National Park (144 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.
