Résumé :
|
The annual report for 2015 is dedicated to the nesting in Wallonia of some sixty uncommon species. The Great White Egret Casmerodius albus, the Mediterranean Gull Larus melanocephalus and the Pygmy Owl Glaucidium passerinum are now confirmed as Wallonian nesting birds. Some other species, such as the Eurasian Spoonbill Platalea leucorodia seem to be almost established (attempt failed), but have suffered some breeding problems. Attention is drawn to the continuation or improvement of the nesting status of some remarkable species - such as the Eurasian Teal Anas crecca and the Red kite Milvus milvus and the Black kite M. migrans. But for most of the species, negative changes predominate; nearing critical levels in, amongst others, the Black Grouse Tetrao tetrix and the Hazel Grouse Bonasa bonasia.
