Sombre Greenbul
Andropadus importunus
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. It has a white iris. The sexes are similar in plumage, but juveniles are even duller than the adult and have dark, grey eyes. There is no colour distinction among sexes. The subspecies A. i. hypoxanthus is much yellower below than the nominate subspecies.

White-browed Bulbul
Pycnonotus luteolus
The white-browed bulbul is about 20 cm (7.9 in) long, with a moderately long (8 centimetres or 3 inches) tail. It has olive-grey upperparts and whitish underparts. This species is identifiable by the white supercilium, white crescent below the eye, and dark eyestripe and moustachial stripe. The vent is yellowish and there is some yellow on the chin and moustache. The throat is, however, largely whitish unlike in the similar looking and sounding yellow-throated bulbul, which is found in rockier habitats. Three or four hair-like filoplumes are present on the nape. Sexes are similar in plumage.
