The rufous-bellied helmetshrike or Gabon helmetshrike (Prionops rufiventris) is a passerine bird belonging to the Vanga family, Vangidae. It inhabits tropical forest in Central Africa. It is sometimes included within the chestnut-bellied helmetshrike (P. caniceps) of West Africa.
It is 20–22 cm long. The adult has glossy black upperparts and throat and reddish-brown underparts with a narrow white breastband. The top and sides of the head and the chin are pale blue-grey and there are bushy whitish feathers on the forehead. The wings are broad and rounded with a white band across the primaries. The bill, legs and feet are orange-red and the eye is yellow with a bare orange-red ring around it. The eastern subspecies P. r. mentalis has darker underparts and a grey-brown eye. Juvenile birds are duller than the adults and have a pale buff-white breast and belly and a largely whitish head. The bill is blackish and the legs and feet are dark orange.
It is a noisy bird with a variety of complex chattering and whistling calls. Birds often call together in a duet or chorus. They also make bill-snapping sounds and the wings produce a sound during flight. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rufous-bellied Helmetshrike is recorded against all the birds logged in Semuliki National Park (79 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.
