This small warbler (only 12 cm) nests in our region in low and dense scrubland (“garrigue”). Sedentary and therefore present throughout the year, but sensitive to cold, its population fluctuates and can be decimated during severe winters. In summer it feeds mainly on caterpillars, beetles, flies and spiders. In winter its diet is probably supplemented by vegetable matter: various grass seeds, berries and grains seem to attract small groups of warblers.
This species has been declining in Europe for some twenty years, especially in the Iberian peninsula where its habitats are gradually shrinking. In France, it still occurs but its numbers fluctuate sharply and need monitoring.
