Résumé :	This winter was characterized by a long cold period with substantial snow cover during December. Many birds abandoned woods, fields, and the frozen open water surfaces. Numerous passages of birds escaping winter conditions were recorded (for example Common Buzzard Buteo butec), together with striking influxes of Rough-legged Buzzards Buteo lagopus and of Northern sub-species Long-tailed tits Aegithalos caudatus caudatus. The wintry conditions increased the presence of birds at bird feeders, including species which normally rarely visit them (Common Wood Pigeon Columba palumbus, Common Linnet Carduelis cannabina, Yellowhammer Emberiza citrinella...).In the countryside too, unharvested cereal areas (agro-environmental measures for wildlife) attracted large numbers of seed eaters, notably Yellowhammer Emberiza citrinella (up to 1000 on a single site). A return to normal winter conditions occurred in early January. Globally there were no significant arrivals of water birds normally overwintering in more northern regions.
