Nine species of fairy-wrens, three emu-wrens and eleven grasswrens are found in Australia and all are endemic. They are small birds and, generally, the adult males are the brightest coloured. They are generally found on the ground or low down in vegetation. The taxonomy of the grasswrens has undergone much change in recent times, from eight species in 1986, then to ten in 2004 and now at eleven. As currently classified, three subspecies of the Western Grasswren Amytornis textilis and two of the Thick-billed Grasswren A. modestus have been declared extinct.
