With luck
About 10% of wildlife watchers report a Yellow-spotted Petronia sighting in Masai Mara National Reserve on a given day, based on 316 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 130th most-seen of the 398 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November and December
In those months about 20% of wildlife watchers report a Yellow-spotted Petronia in Masai Mara National Reserve on a given day, against under 5% in May and June, the lowest months. Those are among Masai Mara National Reserve's wettest months, with about 100 mm of rain a month against 15 mm in July.
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.
9th of 15
Of the 15 parks where we can rate Yellow-spotted Petronia sightings, Masai Mara National Reserve ranks 9th 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 Masai Mara National Reserve (family Passeridae, Old World Sparrows) are Gray-headed Social-Weaver (about 20%), Northern Grey-headed Sparrow (about 10%) and Swahili Sparrow (about 10%), 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 Masai Mara National Reserve (316 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.
