4, but see text Cettia /ˈtʃɛtiːə/ is a genus of small insectivorous songbirds ("warblers") which make up the core of the newly recognized family Cettiidae.

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

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

Megalurid bush warblers tend to be somewhat slimmer and have a very long and pointed tail, but are otherwise very similar.

This latter species differs wildly in its gaudy colors but in habitus is a typical "bush warbler".
