Résumé :	While working on the Northern Goshawks Accipiter gentilis in the "Entre-Sambre-et-Meuse" region, the author found a pair of Ravens Corvus corax nesting well outside their usual breeding area in the Ardennes.Nesting occurred both in 2010 and 2011 in the same nest, located in a wild cherry tree Prunus avium. There were two youngs in each brood, but after fledging only three were seen again. Differents observations are discussed. Most are in line with the ornithological literature. The author comments on two particular observations: a strange variation in the time of appearance of the first egg and the confirmed consumption of corn seeds. The author also reflects on the meaning of the male bird's noisy flight. Has it a particular function ?
