Rare
Under 5% of wildlife watchers report a Waller's Starling sighting in Queen Elizabeth National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 343rd most-seen of the 434 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Waller's Starling in Queen Elizabeth National Park on a given day, against under 5% in November to September, the lowest months. That is one of Queen Elizabeth National Park's wettest months, with about 120 mm of rain against 15 mm in January.
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.
8th of 8
Of the 8 parks where we can rate Waller's Starling sightings, Queen Elizabeth National Park ranks 8th at under 5%. The best odds are in Nyungwe National Park (Rwanda, about 30%), Bwindi Impenetrable National Park (Uganda, about 20%) and Arusha National Park (Tanzania, about 20%).
Same family: Sturnidae
The closest relatives of the Waller's Starling that you can see in Queen Elizabeth National Park (family Sturnidae, Starlings) are Rüppell's Glossy-starling (about 70%), Wattled Starling (about 20%) and Violet-backed Starling (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Waller's Starling is recorded against all the birds logged in Queen Elizabeth National Park (13 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.
