Résumé :	A largely sedentary population of Little Egrets Egretta garzetta has become established throughout the coastal regions of western and northern France. This population is still increasing, but numbers are temporarily reduced by periods of severe winter weather. Cold-weather mortality results in fewer breeding birds in the following spring, but the impact has been insufficient to stall the long-term population growth. Only those birds feeding at saltpans appear able to carry sufficient reserves to last them through cold periods. No significant movements of Little Egrets have been noted at these times, and it is suggested that displaced birds disperse widely into the surrounding area, in search of alternative feeding sites.
