The white-throated greenbul (Phyllastrephus albigularis) or white-throated bulbul, is a species of passerine bird in the bulbul family, Pycnonotidae. It is widespread across the African tropical rainforest. It was formerly considered to be conspecific with the Angola greenbul.
The white-throated greenbul was formally described and illustrated in 1882 by the English ornithologist Richard Bowdler Sharpe based on a specimen collected in the Fantee region of central Ghana. He coined the binomial name Xenocichla albigularis. It is now one of 21 species placed in the genus Phyllastrephus that was introduced in 1832 by the English naturalist William Swainson. The genus name combines Ancient Greek φυλλον/phullon meaning "leaf" with στρεφω/strephō meaning "to toss" or "to turn". The specific epithet albigularis combines Latin albus meaning "white" with Modern Latin gularis meaning "throated". The Angola greenbul was formally considered to be a subspecies. The white-throated greenbul is now monophyletic: no subspecies are recognised. Wikipedia →

With luck
About 10% of wildlife watchers report a White-throated Greenbul sighting in Semuliki National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 138th 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 50%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a White-throated Greenbul in Semuliki National Park on a given day, against under 5% in January, April–May, August and November, the lowest months. That is one of Semuliki National Park's driest months, with about 40 mm of rain against 140 mm in May.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-throated 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.
Yes
Of the 4 parks where we can rate White-throated Greenbul sightings, Semuliki National Park has the highest daily chance: about 10%. Next come Kibale National Park (Uganda, about 10%) and Bwindi Impenetrable National Park (Uganda, under 5%).

GBIF citizen-science records
It is estimated from how often the White-throated Greenbul is recorded against all the birds logged in Semuliki National Park (42 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.
