AppearanceThe Cape Bulbul is 19–21 cm long, mainly dull, blackish brown with a diagnostic white eye-ring, and yellow undertail coverts. The head has a small crest. The short, straight bill, legs and feet are black and the iris is dark brown. The sexes are similar in plumage.
This species is much darker than the other South African bulbuls, and differs in the eye ring colour and brown lower belly, whereas the other dark bulbuls have a pale lower belly. The dark belly helps to identify juveniles, which lack the distinctive eye ring of the adult.
BehaviorThe Cape Bulbul is a common and conspicuous bird, which tends to perch at the top of a bush. It is active and noisy, usually seen in pairs or small groups foraging for fruit, nectar and insects.
The most typical call of this species is a liquid whistle of two or more varied notes ''pit-peet-pitmajol, piet-piet-patata''.
In part of its range, it gets parasitized by the Jacobin cuckoo.
