 They are less wren-like than the typical shrub-warblers ("Cettia") but like these drab brownish or buffy all over.They tend to be larger and slimmer than "Cettia" though, and many have bold dark streaks on wings and/or underside.Most live in scrubland and frequently hunt food by clambering through thick tangled growth or pursuing it on the ground; they are perhaps the most terrestrial of the "warblers".
