Article summary

After a strong decline during the 20th Century, the Red-Backed Shrike Lanius collurio breeding  population has been recovering in Belgium, where 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 land  targeted by one of these projects (“LIFE Prairies bocagères”) 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 Wallonia over the same timeframe. 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.
