Bruce's green pigeon (Treron waalia), also known as the yellow-bellied fruit pigeon or the yellow-bellied green pigeon, is a species of bird in the family Columbidae. Its range extends across the Sudan (region) towards the Red Sea and the Southwestern Arabian foothills savanna and Dhofar Mountains.
It is a frugivore bird species that specialises on eating the fruits of a single species of fig tree, Ficus platyphylla. Unlike most birds, it does not have a uropygial gland. Despite its name, Bruce's green pigeon is mostly grey with a light yellow breast and olive green upper wings. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bruce's Green-Pigeon is recorded against all the birds logged in Niokolo-Koba National Park (28 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.
