Southern Boubou
Laniarius ferrugineus
The male southern boubou is a fairly distinctive 20–22 cm long bird with black upperparts extending from the top of the head down to the tail, a striking white wing stripe, and a relatively long black tail with white outer feathers. The underparts are white shading to rufous on the lower belly, undertail and flanks. The bill, eyes and legs are black. The female is similar to the male, but dark grey above and with a rufous wash to the breast. Young birds are like the female, but mottled buff-brown above, have a buff wash to the wing bar, and are barred below.

Tropical Boubou
Laniarius major
The tropical boubou is fairly large for its family (bushshrikes), measuring 23–25 cm in length. Its weight can vary between about 38-70 g, but typically adults weigh between 50 and 60 g. Females are on average a bit smaller than males, but individual variation is so large that for most practical purposes the sexes seem to be of identical size. The wing measures about 98 mm on average (between 85 and 110), the tail is a mere two millimetres longer both on average and as regards variation. Voice: This species is heard more often than seen, but its calls often help to locate it visually. To vocalize they move higher off the ground than during their usual activities, and may perch on an exposed site. They also nod their head and bow their body when calling, making them even conspicuous sometimes.
