Steenbok are petite, weighing 7-16 kg and measuring 70-95 cm in length. Unlike the crouched stance of forest duikers, steenbok carry their heads high and have long legs, with a shoulder height between 45 and 60 cm. The hindquarters and lower parts/belly are pure white. The male Steenbok have upright, slender horns projecting above the eyes. Conspicuous black, facial glands are situated in front of the large, dark brown eyes. These pre-orbital glands are noticeable in both sexes.
Agamas are active during the day and are often found scampering around to snatch up their favourite foods. They can tolerate greater temperatures than most reptiles, but in the afternoon when temperatures reach around 38 °C they will settle into the shade and wait for it to cool. Frequent fighting breaks out between males; such fighting involves a lot of bobbing and weaving in an attempt to scare the opponent. If it comes to blows, they lash out with their tails and threaten each other with open jaws. Many older males have broken tails as a result of such fights. Females may sometimes chase and fight one another, while hatchlings mimic the adults in preparation for their future.
The African thrush can be found in all sorts of wooded habitats including forest edge, riparian woodland, scrub cultivation, parks and gardens. The African thrush is normally encountered either singly or in pairs and is rather shy and retiring preferring to remain in cover but will come out and gather at fruiting trees. Usually forages in the ground, flicking leaf litter and searching through vegetation. Where undisturbed or habituated to people will feed out in the open in a similar fashion to the song thrush in Europe, and it is also reported to crack open snails on an anvil stone like a song thrush.
