The Golden Greenbul (Calyptocichla serina) is the only member of the Calyptocichla genus of greenbuls. It is not closely related to any of the other greenbul species, forming a separate clade from the two main clades which make up the bulbul family Pycnonotidae.
The Golden Greenbul is brightly coloured for a greenbul due to its bright yellow belly and white throat; otherwise it is not particularly distinct in plumage, with unmarked olive upperparts, tail and wings. It has a long slender pinkish-brown bill, a feature not shared by other greenbuls.
Range and habitat
The species is confined to forests in West Africa and the Democratic Republic of the Congo, where it is common.
