Résumé :
|
European Bittern Botaurus stellaris numbers have declined in the last years in France, just as they have elsew here in Europe. In the Camargue, booming males censuses had not been conducted since 1982-1985 when 70 were recorded (greater Camargue area). In spring 1996, a complete census was carried out on the same area and 138 booming males were recorded. Most of these (55 males) occuned in the eastern part of this area (Plan du Bourg). The most recent estimate for the French breeding population is 300 - 350 pairs.
