A seasonal report is from now dedicated to observations of less common species breeding in Wallonia. This report presents the breeding period of 2013 and 2014 for about seventy species. The regional avifauna has been enriched by a new breeding species: the Mediterranean Gull Larus melanocephalus. The Great White Egret Casmerodius albus and the Pygmy Owl Glaucidium passerinum are confirmed as.Wallonian species.Other species that seem likely to establish include the Eurasian Spoonbill Platalea leucorodia and Glossy Ibis Plegadis falcinellus. Attention is also drawn to the persistence and/or increase of certain other species. These include, for instance, the Eurasian Teal Anas crecca (which is supported by the restoration work by LIFE in the Hautes-Fagnes), the six species of ardeidae nesting at Harchies, the Black Kite Milvus migrans and the Red Kite Milvus milvus, the Wryneck Jynx torquilla, the Wood Lark Lullula arborea and the Common Raven Corvus corax.Unfortunately, negative trends prevail. Species whose numbers have sunk to critical levels include Black Grouse Tetrao tetrix, Hazel Grouse Bonasa bonasia, Corn Crake Crex crex (none of which been seen in 2014) and the Grey-headed Woodpecker Picus canus. Others are clearly endangered species (for example, Common Gull Larus canus and Great Grey Shrike Lanius excubitor).There was no recent breeding evidence of such emblematic species as the Eurasian Bittern Botaurus stellaris, Spotted Crake Porzana porzana, Common Snipe Gallinago gallinago, or Short-eared Owl Asio flammeus.
