The black-headed mountain greenbul (Arizelocichla nigriceps), also known as the mountain greenbul or eastern mountain greenbul, is a species of the bulbul family of passerine birds. It is found in eastern Africa. Its diet consists of fruit and nectar.

Taxonomy and systematics

The black-headed mountain greenbul was originally described in the genus Xenocichla (a synonym for Bleda), then classified in Andropadus and, in 2010 re-classified to the new genus Arizelocichla. Alternatively, some authorities classify the black-headed mountain greenbul in the genus Pycnonotus. Some authorities also consider the olive-breasted mountain greenbul to be a subspecies of the mountain greenbul, while others consider the mountain greenbul itself to be a subspecies of the western mountain greenbul. The common name, 'mountain greenbul', is also used as an alternate name for the western and Cameroon greenbuls.
