Cettia
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 southeast Asia. The genus gets its name from the Cetti's warbler, itself named after the 18th century Italian zoologist Francesco Cetti. 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. Taxonomy. The genus "Cettia" was erected in 1834 by the French ornithologist Charles Lucien Bonaparte to accommodate Cetti's warbler ("Cettia cetti"). The specific epithet "cetti" had been chosen in 1820 by Coenraad Jacob Temminck to commemorate the Italian zoologist Francesco Cetti. This genus and the genus "Horornis" have been split. Cetti's warbler ("C. cetti"), the type species, seems close  to the genus "Tesia" from Southeast Asia and neighboring regions. Species in the genus "Horornis", such as the famous "uguisu" (鶯, Japanese bush warbler, "H. diphone") and the brown-flanked bush warbler ("H. 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".
