The megalurid bush warblers are related to the grass warblers of Locustella and Megalurus, but share lifestyle and related adaptations and apomorphies with Cettia, the other genus of bush warblers. These belong to an older lineage of Sylvioidea. Both "bush warbler" genera are smallish birds well adapted to glimbing among shrubbery. They are markedly long-tailed birds, at first glance somewhat reminiscent of wrens.
These are quite terrestrial birds, which live in densely vegetated habitats like thick forest and reedbeds. The will walk away from disturbance rather than flush. The plumage similarities and skulking lifestyle makes these birds hard to see and identify.
Megalurid bush warblers tend towards greyish browns above and buffish or light grey tones below. They have little patterning apart from the ubiquitous supercilium. Altogether, they appear much like the plainer species among Acrocephalus marsh-warblers in coloration. Cettid bush warblers tend to be somewhat more compact, with less pointed tails, but are otherwise very similar.
