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.

Likely
About 40% of wildlife watchers report a Bruce's Green-Pigeon sighting in Mole National Park on a given day, based on 153 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd most-seen of the 266 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 60% of wildlife watchers report a Bruce's Green-Pigeon in Mole National Park on a given day, against about 20% in February and June, the lowest months. That is one of Mole National Park's wettest months, with about 190 mm of rain against almost none in January. July has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Bruce's Green-Pigeon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Bruce's Green-Pigeon is recorded against all the birds logged in Mole National Park (153 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.
