The range of this genus extends through the warm regions from Africa around the Indian Ocean and far into Asia.

Both "bush warbler" genera are smallish birds well adapted to climbing among shrubbery.

These are quite terrestrial birds, which live in densely vegetated habitats like thick forest and reedbeds.

Locustellid bush warblers tend towards greyish browns above and buffish or light grey tones below.

Cettiid bush warblers tend to be somewhat more compact, with less pointed tails, but are otherwise very similar.
