Possible
About 30% of wildlife watchers report a Waller's Starling sighting in Nyungwe National Park on a given day, based on 404 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 45th most-seen of the 252 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Waller's Starling in Nyungwe National Park on a given day, against about 10% in March and November, the lowest months. That is one of Nyungwe National Park's driest months, with about 30 mm of rain against 550 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Waller's Starling 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 8 parks where we can rate Waller's Starling sightings, Nyungwe National Park has the highest daily chance: about 30%. Next come Bwindi Impenetrable National Park (Uganda, about 20%) and Arusha National Park (Tanzania, about 20%).
GBIF citizen-science records
It is estimated from how often the Waller's Starling is recorded against all the birds logged in Nyungwe National Park (404 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.
