The yellow-bearded greenbul (Criniger olivaceus) is a species of songbird in the bulbul family, Pycnonotidae. It is found in western Africa. Alternatively, the yellow-bearded greenbul has been classified in the genus Xenocichla (a synonym for Bleda) and has also been considered as conspecific with the white-bearded greenbul. Alternate names for the yellow-bearded greenbul include the olive bulbul, olive greenbul, olive-bearded bulbul, yellow-bearded bulbul, yellow-throated olive bulbul and yellow-throated olive greenbul. The name 'olive bulbul' should not be confused with the species of the same name, Iole virescens.
It is found in West Africa from eastern Sierra Leone to south-western Ghana. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.

It is the 242nd most-seen of the 250 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-bearded Greenbul in Kakum National Park on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Yellow-bearded Greenbul is recorded against all the birds logged in Kakum National Park (5 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.
