The mountain sooty boubou (Laniarius poensis), western boubou or mountain boubou, is a species of bird in the family Malaconotidae. It was formerly considered conspecific with the Albertine sooty boubou (Laniarius holomelas), with Willard's sooty boubou (Laniarius willardi), and with Fülleborn's sooty boubou (Laniarius fuelleborni).
It is found in the Cameroon line from Bioko, Equatorial Guinea north to Mount Oku, Cameroon and the Obudu Plateau, Nigeria. In the Cameroon highlands, it is found in montane forests, usually above 600 m in elevation. On Mount Cameroon, this species can occur at extremely low elevations on the windward slopes near the coast, with records from as low as c. 520 m above sea level. On both Bioko and Mt. Cameroon, this taxon is restricted to montane forests. Wikipedia →

Possible
About 20% of wildlife watchers report a Western Boubou sighting in Volcanoes National Park on a given day, based on 84 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 156 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July and August
In those months about 30% of wildlife watchers report a Western Boubou in Volcanoes National Park on a given day, against about 10% in February–May and October–December, the lowest months. Those are among Volcanoes National Park's driest months, with about 30 mm of rain a month against 250 mm in April.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Western Boubou sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Western Boubou sightings, Volcanoes National Park has the highest daily chance: about 20%. Next come Nyungwe National Park (Rwanda, about 20%) and Bwindi Impenetrable National Park (Uganda, about 10%).
GBIF citizen-science records
It is estimated from how often the Western Boubou is recorded against all the birds logged in Volcanoes National Park (84 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.
