Possible
About 20% of wildlife watchers report a Waller's Starling sighting in Bwindi Impenetrable National Park on a given day, based on 391 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th most-seen of the 400 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February to May
In those months about 30% of wildlife watchers report a Waller's Starling in Bwindi Impenetrable National Park on a given day, against about 10% in January and September–November, the lowest months.
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.
2nd of 8
Of the 8 parks where we can rate Waller's Starling sightings, Bwindi Impenetrable National Park ranks 2nd at about 20%. The best odds are in Nyungwe National Park (Rwanda, about 30%).
GBIF citizen-science records
It is estimated from how often the Waller's Starling is recorded against all the birds logged in Bwindi Impenetrable National Park (391 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.
