The swamp boubou (Laniarius bicolor), also known as the Gabon boubou, is a species of bird in the Malaconotidae or bushshrike family. It is native to western and southern Central Africa. In the north of their range, savannah thickets constitute an important part of their habitat, while in the south they are strongly associated with river systems and marshes, for which they are named. The pair bond appears to be maintained by duetting, which in the south is generally synchronous or overlapping. It is most similar to L. major major, with which it perhaps hybridizes, but the underpart plumage is immaculate white, while the female contributes a ratchet-like note to the duet.
It is found in Angola, Botswana, Cameroon, Republic of the Congo, DRC, Gabon, Namibia, Zambia, and Zimbabwe. Its natural habitats are regenerating forest, moist to seasonally dry savannah thicket, coastal scrubland and mangroves, and ravine forests of the Angolan escarpment. In the south of its range it is confined to floodplain systems. Along these rivers and swamps they frequent dense, tangled riparian vegetation, edges of reedbeds, papyrus stands or clumps of water fig on islands. Wikipedia →

Possible
About 20% of wildlife watchers report a Gabon Boubou sighting in Moremi Game Reserve on a given day, based on 234 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 95th most-seen of the 334 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.
December
In that month about 30% of wildlife watchers report a Gabon Boubou in Moremi Game Reserve on a given day, against about 10% in January–February and April–July, the lowest months. That is one of Moremi Game Reserve's wettest months, with about 85 mm of rain against almost none in May.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Gabon Boubou sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Gabon Boubou sightings, Moremi Game Reserve has the highest daily chance: about 20%. Next come Chobe National Park (Botswana, about 10%).
GBIF citizen-science records
It is estimated from how often the Gabon Boubou is recorded against all the birds logged in Moremi Game Reserve (234 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.
