The sombre greenbul (Andropadus importunus) is a member of the bulbul family of passerine birds. It is a resident breeder in coastal bush, evergreen forest and dry shrub land in eastern and southern Africa. It is the only member of the genus Andropadus.
Taxonomy and systematics
[edit | edit source]Eighteen species of greenbuls originally described in the genus Andropadus were re-classified to the genera Arizelocichla, Stelgidillas and Eurillas in 2010.[2] This has left Andropadus as a monotypic genus with the sombre greenbul remaining as its sole extant species.[3]
The sombre greenbul was originally described in the genus Turdus and was later re-classified to the genus Andropadus. Alternatively, some authorities classify the sombre greenbul in the genus Pycnonotus. Alternate names for the sombre greenbul include the sombre bulbul, southern sombre bulbul and southern sombre greenbul.[4]
Subspecies
[edit | edit source]Four subspecies of the sombre greenbul are recognized:[3]
- Zanzibar sombre greenbul (A. i. insularis) - Hartlaub, 1861: Originally described as a separate species. Includes Frick's greenbul which was also originally described as a separate species. Found from southern Ethiopia and southern Somalia to eastern Tanzania
- Transvaal sombre greenbul (A. i. importunus) - (Vieillot, 1818): Found from the highlands of northern South Africa and western Eswatini south along coast to Western Cape
- Endoto sombre greenbul (A. i. oleaginus) - Peters, W, 1868: Found in southern Zimbabwe, southern Mozambique and lowland northern South Africa
- A. i. hypoxanthus - Sharpe, 1876: Found in south-eastern Tanzania to central Mozambique, central Zimbabwe and south-central Zambia

Description
[edit | edit source]
The sombre greenbul is 15–18 cm long, with mainly dull greyish olive-green plumage, paler on the underparts than above. There are variations in colour based on habitat range. Individuals located in southern Africa tend to be plain, olive-green. To the north, birds are yellower with greener upper parts.[27] It has a white iris. The sexes are similar in plumage, but juveniles are even duller than the adult and have dark, grey eyes.[27] There is no colour distinction among sexes.[27] The subspecies A. i. hypoxanthus is much yellower below than the nominate subspecies.
The sombre greenbul is a vocal species, and the most typical call is a monotonous, ringing phrase starting with a penetrating single whistle weeeewee, followed by a jumbled chortle and ending off with a rather plaintive, drawn-out whistle willy. If agitated, a call of peeet peeet peeet repeatedly is likely to be heard.[27]
Behaviour and ecology
[edit | edit source]The sombre greenbul is a common bird, which tends to stay hidden in foliage and is more often heard than seen. It is usually found in pairs or small groups foraging for insects, fruit and small snails.
