Field Identification

c. 17 cm; 41–63 g. Male brown , with bare blackish-grey head ; pale bristly tufts around base of bill; secondaries and tertials narrowly edged yellowish; bill yellow to light brown. Distinguished from G. bona­partei by pale bill, bare face, and lack of grey on neck; from G. calvus by smaller bill, indistinct yellowish-buff edges to wing feathers, and bristly tufts above bill; from G. sladeni by paler, more yellow-brown coloration, more yellow on wings, paler bill. Female like male. Immature has feathered brown head, soft darker tufts about head, and darker bill than adult.

Systematics History

Closely related to G. sladeni; both also rather close to G. calvus. Monotypic.

Subspecies

Monotypic.

Distribution

S Sierra Leone E to S Cameroon, Congo and W DRCongo and S to Gabon and Cabinda (N Angola).

Habitat

Primary and dense secondary forest and nearby fruiting trees, riverine swamps in high forest, also logged forest and plantations. In lowlands to 1100 m.

Movement

Resident, and sedentary.

Diet and Foraging

Fruits and insects. Hangs in manner of tit (Paridae) to secure fruits. Feeds in fruiting trees with often more common G. bonapartei and, especially, G. calvus.

Sounds and Vocal Behavior

Series up to 5 seconds long of soft hoots; “pyew” notes pitched higher than those of G. calvus; “tyee” chatters or rattles.

Breeding

Apparently Sept–Jan in Liberia, Nov–Dec in Ghana, May–Jun in Nigeria, most of year but especially in dry season in Cameroon, and Oct–Apr in Gabon. Nests colonially, either alone or with G. calvus and to lesser extent G. bonapartei. Nest and eggs undescribed, but holes of this species observed at 10–35 m in trees.
Not globally threatened. Status uncertain. Little known, and possibly overlooked; easily confused with G. calvus and G. bonapartei; further information required, especially since it is usually less common than those 2 species; may have special requirements, as yet unidentified, so possible that any pressures on it remain to be elucidated. Favoured, at least temporarily, by forest clearance. Known to occur in Gola Forests Reserves (Sierra Leone) and Taï Forest National Park (Ivory Coast).
