Cettia is a genus of small insectivorous songbirds ("warblers") which make up the core of the newly recognized family Cettiidae. They were formerly placed in the Sylviidae, which at that time was a wastebin taxon for the warbler-like Sylvioidea. The range of this genus extends from Europe to the western Pacific. The most recently described species is the Odedi (Cettia haddeni) from Bougainville.

The cettiid or typical bush-warblers share the lifestyle and related adaptations and apomorphies with Bradypterus, the other genus called bush-warblers. However, Bradypterus is related to the grass-warblers of Locustella and Megalurus and is more distant from Cettia. Both "bush-warbler" genera are smallish birds well adapted to climbing 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 such as thick forest and reedbeds. They will walk away from disturbance rather than flush. The plumage similarities and skulking lifestyle makes these birds hard to see and identify.

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

Species

This genus appears to be non-monophyletic. It seems that it will be split eventually. Cetti's Warbler (C. cetti), the type species, seems close to the genus Tesia from Southeast Asia and neighboring regions. Others, such as the famous uguisu (鶯, Japanese Bush-warbler, C. diphone) and the Brownish-flanked Bush-warbler (C. fortipes) belong to a group that might include the aberrant Broad-billed Warbler (Tickellia hodgsoni). This latter species differs wildly in its gaudy colors but in habitus is a typical "bush-warbler".[1]
