Résumé :	After a strong decline during the 20th Century, he Red-Backed Shrike Lanius collurio breeding population has been recovering in Belgium, here the species is mostly found in the Southern half of Wallonia. Its main habitat, extensive hay meadows bordered by hedgerows or bushes, is the focus of restoration projects inside the Natura 2000 site network. A comprehensive inventory of Red-Backed Shrike breeding territories was repeated during a six-year period, in an area of 4.600 ha of open and targeted by one of these projects ("LIFE Prairies bocageres") in the Fagne-Famenne region. Within this study area, the breeding population increased from 200 territories in 2013 to 407 in 2019. This Increase is 1,5 to 3 times larger than the average rate observed in Wal-lonia over the same time frame. Direct drivers behind this dynamic are not yet quite well understood, but may include favorable evolution of the species habitat, especially preserved in nature reserves, covering now 9% of the open habitats in this area.
