With luck
About 10% of wildlife watchers report a Yellow-spotted Petronia sighting in Nairobi National Park on a given day, based on 120 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 200th most-seen of the 371 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June–September and November–April
In those months about 10% of wildlife watchers report a Yellow-spotted Petronia in Nairobi National Park on a given day, against under 5% in May and October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-spotted Petronia sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 15
Of the 15 parks where we can rate Yellow-spotted Petronia sightings, Nairobi National Park ranks 10th at about 10%. The best odds are in Mkomazi National Park (Tanzania, about 40%), Tsavo West National Park (Kenya, about 30%) and Samburu National Reserve (Kenya, about 30%).
Same family: Passeridae
The closest relatives of the Yellow-spotted Petronia that you can see in Nairobi National Park (family Passeridae, Old World Sparrows) are Kenya Rufous Sparrow (about 60%) and White-browed Sparrow-Weaver (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-spotted Petronia is recorded against all the birds logged in Nairobi National Park (120 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.
