The black-headed mountain greenbul (Arizelocichla nigriceps), also known as the mountain greenbul or eastern mountain greenbul, is a species of the bulbul family of passerine birds. It is native to the eastern Afromontane. Its diet consists of fruit and nectar.
The black-headed mountain greenbul was originally described in the genus Xenocichla (a synonym for Bleda), then classified in Andropadus and, in 2010 re-classified to the new genus Arizelocichla. Alternatively, some authorities classify the black-headed mountain greenbul in the genus Pycnonotus. Some authorities also consider the olive-breasted mountain greenbul to be a subspecies of the mountain greenbul, while others consider the mountain greenbul itself to be a subspecies of the western mountain greenbul. The common name, 'mountain greenbul', is also used as an alternate name for the western and Cameroon greenbuls. Wikipedia →

Possible
About 20% of wildlife watchers report an Eastern Mountain Greenbul sighting in Arusha National Park on a given day, based on 144 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 84th most-seen of the 373 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February and August–October
In those months about 30% of wildlife watchers report an Eastern Mountain Greenbul in Arusha National Park on a given day, against about 10% in March and December, the lowest months. Those are among Arusha National Park's driest months, with about 95 mm of rain a month against 440 mm in April.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eastern Mountain Greenbul sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Eastern Mountain Greenbul sightings, Arusha National Park has the highest daily chance: about 20%. Next come Ngorongoro Conservation Area (Tanzania, about 10%).
GBIF citizen-science records
It is estimated from how often the Eastern Mountain Greenbul is recorded against all the birds logged in Arusha 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.
