Karoo thrush

It has traditionally been considered a subspecies of the olive thrush (with which it is known to hybridize), but is increasingly treated as a separate species.

The specific name honours the Scottish military surgeon and zoologist Sir Andrew Smith.

[2] This medium-sized bird has a length of about 24 cm.

It can reach a mass of at least 86 g. It differs from the olive thrush by its longer, entirely yellow bill, its longer wings, and its greyer flanks.

It occurs in South Africa, where it is present in Little Namaqualand, the Karoo and Northern Cape, Free State, Gauteng, Limpopo, Mpumalanga and parts of the North West Province.
