Cetti's warbler (Cettia cetti) is a small, brown warbler in the family Cettiidae, which breeds in southern and western Europe, northwest Africa and the east Palearctic as far as Afghanistan and northwest Pakistan. The sexes are alike. The bird is named after the 18th-century Italian zoologist, Francesco Cetti. This species is often difficult to see because of its skulking habits.
Cetti's warbler was described in 1820 by the Dutch zoologist Coenraad Jacob Temminck from specimens collected by Alberto della Marmora in Sardinia. Temminck coined the binomial name Sylvia cetti. The specific epithet was chosen to commemorate the Italian zoologist Francesco Cetti. Cetti's warbler is now placed in the genus Cettia that was erected in 1834 by the French ornithologist Charles Lucien Bonaparte, a nephew of Napoleon, with Cetti's warbler as the type species.
The phylogenetic relationships among the Cettia species are shown below, based on the data by the Cornell Lab of Ornithology. Wikipedia →

Rare
Under 5% of wildlife watchers report a Cetti's Warbler sighting in Cévennes National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 118th most-seen of the 126 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Cetti's Warbler in Cévennes National Park on a given day, against under 5% in November to September, the lowest months. That is one of Cévennes National Park's wettest months, with about 260 mm of rain against 35 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cetti's Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 11
Of the 11 parks where we can rate Cetti's Warbler sightings, Cévennes National Park ranks 8th at under 5%. The best odds are in Camargue (France, about 60%), Doñana National Park (Spain, about 50%) and Monfragüe National Park (Spain, about 50%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Cetti's Warbler that you can see in Cévennes National Park (order Passeriformes, Perching Birds) are Chaffinch (about 70%), Great Tit (about 60%) and Eurasian Blackbird (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cetti's Warbler is recorded against all the birds logged in Cévennes National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
