Rare
Under 5% of wildlife watchers report an Olive-headed Greenbul sighting in Ngorongoro Conservation Area on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 485th most-seen of the 519 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report an Olive-headed Greenbul in Ngorongoro Conservation Area on a given day, against under 5% in October to August, the lowest months. That is one of Ngorongoro Conservation Area's driest months, with about 5 mm of rain against 190 mm in April.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Olive-headed 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.
3rd of 3
Of the 3 parks where we can rate Olive-headed Greenbul sightings, Ngorongoro Conservation Area ranks 3rd at under 5%. The best odds are in Arusha National Park (Tanzania, about 30%) and Mkomazi National Park (Tanzania, about 20%).
GBIF citizen-science records
It is estimated from how often the Olive-headed Greenbul is recorded against all the birds logged in Ngorongoro Conservation Area (7 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.
