The sombre greenbul (Andropadus importunus) is 15-18 cm long, with mainly dull greyish olive-green plumage, paler on the underparts than above. It has a white iris. The sexes are similar in plumage, but juveniles are even duller than the adult and have dark eyes. The subspecies A. i. hypoxanthus is much yellower below than the nominate subspecies. The sombre greenbul is a common bird, which tends to stay hidden in foliage and is more often heard than seen.
Habitat and Distribution
It is a resident breeder in coastal bush, evergreen forest and dry shrub land in eastern Africa from Ethiopia to the Cape in South Africa.
It is usually found in pairs or small groups foraging for insects, fruit and small snails.
Calls and Songs
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.
