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.

Yellow-crowned Gonolek
Laniarius barbarus
The yellow-crowned gonolek is 22 cm (8.7 in) long with a long tail and short wings. The adult is a vividly-coloured bird, although easily overlooked as it lurks in undergrowth. It has solidly black upper parts apart from its golden crown, and scarlet underparts other than a buff-yellow undertail. The legs are dark. Sexes are similar, but juveniles are paler and duller.
