Appearance
It can reach a length of 24 cm and a mass of at least 101 grams. The tail and the upperparts are coloured dull olive brown. The belly is white and the rest of the underparts have an orange hue. The throat is speckled with white spots. It can be found in evergreen forests, parks, and gardens. Its diet consists of earthworms, insects, snails, fruits, and spiders.
Naming
In southern Africa alone, there are five subspecies which differ mainly in the relative amounts of white, orange and brown on the underparts: ''T. o. swynnertoni'', ''T. o. transvaalensis'', ''T. o. olivaceus'', ''T. o. pondonensis'', and ''T. o. culminans''. The Karoo Thrush , the Somali Thrush and the Taita Thrush are variously included as subspecies of the Olive Thrush or considered separate species, of which the last is critically endangered. Additionally, the taxa from the northern part of its range are sometimes regarded as one or several separate species .
Reproduction
The female builds a cup nest, typically 2 to 9 m above the ground in a tree or hedge. The 1–3 eggs are incubated solely by the female for 14–15 days to hatching, and the chicks fledge in another 16 days.The male's song is a mix of fluted, whistled and trilled phrases, which varies geographically. It occasionally mimics other birds.
