Résumé :	In 1996, the first systematic survey of Cetti's Warblers Cettia cetti in the United Kingdom and the Channel Islands located a total of 536-593 singing males at 168 sites in 26 counties across southern Britain and on Jersey. This was the largest number recorded since the species first colonised in the early 1970s. Two-thirds of the population was found in only four counties (Hampshire, Dorset, Devon and Somerset) and one-fifth at three individual sites. Cetti's Warblers showed a clear preference for areas of scattered scrub in reed-bed, reed-swamp and by open water. Territory density in these favoured habitats was 0.4-2.1 per ha.
