Résumé :	After March 4 the migratory movements which began in late January-February gathered pace. The following three weeks allowed rapid movements and the return of some early migrants, for example Black Kites Milvus migrans on 5th March and Barn Swallows Hirundo rustica on the 8th March. Towards the end of March early April, weather conditions worsened but then migration started again. Only few species, for example Sand Martin Riparia riparia, Sedge Warbler Acrocephalus schoenobaenus and Willow Warbler Phylloscopus trochilus, started their migration a bit late. In late April and early May, conditions worsened again, blocking the movement of such unexpected species as a couple of Red-breasted Merganser Mergus serrator in the Fagne region.After that, periods of anticyclonic conditions allowed the sighting of various rare migrators: Red-throated Diver Gavia stellata, Red-footed Falcon Falco vespertinus, Spotted Crake Porzana porzana, Stone-curlew Burhinus oedicnemus, Whiskered Tern Chlidonias hybrida and White-winged Black Tern Chlidonias leucopterus, Red-throated Pipit Anthus cervinus, Woodchat Shrike Lanius senator... Mid May to mid June saw an exceptional appearance of some large raptors: Golden Eagle Aquila chrysaetos on May 17, Short-toed Eagle Circaetus gallicus on May 27, Steppe Eagle Aquila nipalensis on May 28, Eurasian Black Vulture Aegypius monachus 28-30 May, Griffon Vulture Gyps fulvus 6-7 June, and Bonelli's Eagle Aquila fasciata on June 14.
