Rare
Under 5% of wildlife watchers report a Gray-olive Greenbul sighting in Nairobi on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 224th most-seen of the 234 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Gray-olive Greenbul in Nairobi on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Gray-olive 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.
Only Nairobi, in our data
Nairobi is the only city on Wallace's Line with enough records to rate Gray-olive Greenbul sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gray-olive Greenbul is recorded against all the birds logged in Nairobi (7 verified sightings), 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.
