The Karoo thrush (Turdus smithi), also known as Smith's thrush, is a member of the thrush family in Africa. 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]
