Sombre Greenbul

The sombre greenbul, Andropadus importunus, is a modestly adorned bird, cloaked in a predominantly dull greyish olive-green plumage. This unassuming avian resident measures between 15 to 18 centimetres in length. The underparts are a shade paler than the upper parts, with variations in coloration depending on the bird's habitat range. Birds in southern Africa exhibit a more uniform olive-green, while their northern counterparts are tinged with yellow and greener upper parts. A distinctive white iris punctuates its otherwise muted appearance. Both sexes are similarly attired, and the juveniles present an even more subdued look with dark, grey eyes.

Identification Tips

To identify the sombre greenbul, look for its olive-green plumage, which is paler below, and the white iris that stands out against its otherwise drab coloration. Juveniles are duller with grey eyes. The subspecies A. i. hypoxanthus is notably yellower on the underside compared to the nominate.

Habitat

The sombre greenbul is a denizen of coastal bush, evergreen forests, and dry shrublands, where it remains largely concealed within the foliage.

Distribution

This bird is a resident breeder in eastern and southern Africa, with its range extending from southern Ethiopia and Somalia down to eastern Tanzania, and from the highlands of northern South Africa and western Eswatini down the coast to the Western Cape.

Behaviour

A common bird, the sombre greenbul is more often heard than seen due to its preference for staying hidden in the foliage. It is typically encountered in pairs or small groups as it forages for insects, fruit, and small snails.

Song & Calls

The vocal repertoire of the sombre greenbul includes a monotonous, ringing phrase that begins with a sharp whistle, followed by a chortle, and concludes with a plaintive, extended whistle. When agitated, it emits a repetitive peeet sound.

Diet and Feeding

The sombre greenbul's diet consists of insects, fruit, and small snails, which it seeks out in its natural habitat.

Conservation status

The IUCN Red List has classified the sombre greenbul as Least Concern, indicating that it currently faces no significant threats to its survival.
