French: Bulbul aux ailes olive German: Malaienbülbül Spanish: Bulbul Aliverde
Other common names: Olive-brown/Large Olive Bulbul

Taxonomy: P[ycnonotus]. plumosus Blyth, 1845, Singapore.
Genus as currently constituted probably polyphyletic; in-depth analysis of morphology, voice, behaviour and genetics required to redefine its limits. Present species previously included in genus Brachypus, which possibly merits resurrection; further study required to clarify relationships. Race name insularis previously considered invalid (and replaced by new name hachisukae), as preoccupied by a race of Andropadus importunus (formerly included in expanded present genus).

Taxonomy: P[ycnonotus]. plumosus Blyth, 1845, Singapore.
Genus as currently constituted probably polyphyletic; in-depth analysis of morphology, voice, behaviour and genetics required to redefine its limits. Present species previously included in genus Brachypus, which possibly merits resurrection; further study required to clarify relationships. Race name insularis previously considered invalid (and replaced by new name hachisukae), as preoccupied by a race of Andropadus importunus (formerly included in expanded present genus). Races porphyreus, hutzi and insularis only dubiously separable; full review required in order to assess their validity. Other described races are chiroplethis (Anamba Is), billitonis (Belitung) and sibergi (Bawean I) all barely distinguishable from nominate, and treated as synonyms of it. Five subspecies provisionally recognized.
