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 Odzala-Kokoua National Park (9 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.
