Identification
Cetti's Warbler is a small bird with discreet plumage and behaviour. With its thin beak and its posture, it resembles a warbler. The upper parts are warm brown, clearly tinged with chestnut. The flight feathers and the tail feathers are dark brown. The primary projection is very short. Although it has only 10 tail feathers (the norm is 12), its tail is wide (family character) and slightly rounded at the tip, the feathers edged with chestnut.
The head has a pale eyebrow which sometimes widens at the back of the eye, becoming diffuse. A grey tinge covers the sides of the neck and head. The throat is white to cream. The dark eye is marked by a white eye arc that contrasts with its upper homologous, merged into the eyebrow. The thin and fairly short beak is black, with the base of the lower mandible paler, pink.
The lower parts are dark khaki, with the chest invaded by the same grey as the cheeks. The robust legs are yellowish, rosaceous or reddish.
The juvenile has a duller plumage.
It could be confused with the Common Grasshopper Warbler which can frequent the same reed beds, but the latter is colder brown, does not have the grey tint in the front of the body, has a stronger beak and shows very long undertail feathers.

Voice song and cries
The song of the Cetti's Warbler is a short, explosive phrase, very loud, made of notes in quick succession, the first detached from the others. It can be translated with the following onomatopoeia TÍ tipitipitipi ti-pi-ti-pi. It has several calls, a plip like a sparrow, a low and dry pset, a uit like a wren, but more emphasized. A churr of a river warbler punctuates interactions between individuals. The alarm call is a rapid succession of tit or tet which can even go into a trill and is reminiscent of the equivalent call of the wren which by the way can frequent the same places.
Habitat
Cetti's Warbler is found at least in western Europe in densely vegetated wet areas with bushes such as willows, brambles, plum trees, etc. along rivers, pools, marshes, irrigated crops and on the margins of wet woodlands such as alder, poplar, riparian habitats. Phragmites marshes are especially sought. They are always close to water but the tree cover should not be too extensive. Further east, it is also found in more open wetlands with small copses along streams, including at high altitude.
Behaviour character trait
The presence of the Cetti's Warbler is most often detected by its song. Indeed, it lives hidden in the cover of vegetation and rarely shows itself in the open.
This cettiid is mainly sedentary to the west of its range and can therefore be affected by severe cold winters to the point of disappearing abruptly from a territory, as was the case in northern France in January 1985.
Flight
Its flight is low and direct, for example when it moves from one bush to another. Its short wings do not allow for sustained flight over long distances and eastern migrants make night stops when heading to their wintering grounds.
Dietfeeding habits
The Cetti's Warbler is an omnivorous insectivore. It feeds on insects and their larvae, as well as spiders, small molluscs, worms, etc. It looks for food on the ground like a troglodyte or even a small mammal.
Reproduction nesting
Cetti's Warbler is known for frequently practicing polygamy, particularly where it is common. Females normally make two successive nests.
Geographic range
Cetti's Warbler occupies a variable width band that stretches from the Atlantic to central Asia and eastern Kazakhstan. To the west, it is mainly Mediterranean, occupying the coast of the Mediterranean, except for Libya and Egypt, but it also moves north on the Atlantic coast due to the oceanic climate. This is why it can be found everywhere in France, except for the extreme northeast, and occasionally in the south-east of the UK. It is sedentary there.
On the other hand, the populations of the extreme south of western Russia, Kazakhstan and inner Turkey are migratory and winter in the southern part of the nesting area, but also disjointly up to the Persian Gulf and the north of the Indian Ocean.
