It is a conspicuous bird, which tends to sit at the top of a bush. As with other bulbuls they are active and noisy birds. The flight is bouncing and woodpecker-like.
Habitat and Distribution
It is a common resident breeder in much of Africa. It is found in woodland, coastal bush, forest edges, riverine bush, montane scrub, and in mixed farming habitats. It is also found in exotic thickets, gardens, and parks.
This species eats fruit, nectar, and insects.
This species nests throughout the year in the moist tropics, elsewhere it is a more seasonal breeder with a peak in breeding coinciding with the onset of the rainy season. The nest is fairly rigid, thick walled, and cup-shaped. It is situated inside the leafy foliage of a small tree or shrub. Two or three eggs is a typical clutch. It, like other bulbuls, is parasitised by the Jacobin cuckoo.
