Epthianura is a genus of bird also known as the Australian chats. Along with the gibberbird in the genus Ashbyia they were once thought to constitute a separate family, the Epthianuridae, although most taxonomists today treat them as a subfamily, Epthianurinae, of the honeyeater family Meliphagidae.
The genus Epthianura is endemic to the continent of Australia, where they are widely distributed across the mainland and, in the case of the white-fronted chat, Tasmania. With the exception of that species they are generally distributed in the central part of Australia; the white-fronted chat being the most coastal species. The Australian chats have adapted to a wide range of habitat types in the interior of Australia, though they generally are found in more shrubby environments than wooded ones and are also seldom found in high altitudes. They are particularly adapted to arid environments, but also frequent riparian woodlands, temporary and permanent wetlands, herblands, and even human modified farmlands.
There are large gaps in the knowledge of the migratory movements of the Australian chats. Some species are apparently nomadic, at least over parts of their range, and others migratory, but the difficulty in reaching and surveying much of their habitat (and the avoidance of the centre of Australia during the height of summer by many observers) means that complete picture of these movements has not yet been obtained. It is also apparent that many of these movements are not only seasonal but dependent on weather conditions, birds may be common in on locality in some years but not in others. This nomadism allows them to make use of unpredictable rainfall in the arid deserts.
