The little greenbul (Eurillas virens) is a species of the bulbul family of passerine birds. It is found in many parts of sub-Saharan Africa. The little 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.
Includes Hall's greenbul (Eurillas virens [hallae]), named after the British ornithologist Pat Hall and which is only known from a single specimen taken in the Democratic Republic of the Congo. Hall's greenbul may be a melanistic form of E. v. zombensis... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Little Greenbul is recorded against all the birds logged in Arusha National Park (84 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.
