The Asian Desert Warbler is a tiny, sandy-toned warbler of semi-desert and dry steppe, breeding from the Volga delta across Central Asia to western Mongolia and wintering from Arabia to north-western India. It is pale grey-brown above and whitish below, with a rufous tail, yellowish bill and legs and a pale yellow eye. Once lumped with the African Desert Warbler, it is now treated as a separate species. It is a rare vagrant to Europe, mostly in late autumn.
