This special issue of our Ringing & Migration journal fills an important gap in the resources for bird ringers and researchers working on European birds. It describes the moults of the Eurasian Hoopoe Upupa epops, European Bee-eater Merops apiaster, Common Kingfisher Alcedo atthis ispida and A. a. atthis, Eurasian Wryneck Jynx torquilla, Great Spotted Woodpecker Dendrocopos major, White-backed Woodpecker Dendrocopos leucotos, European Green Woodpecker Picus viridis, and Grey-headed Woodpecker Picus canus. For these species and some more woodpecker species (Eurasian Three-toed Woodpecker Picoides tridactylus, Middle Spotted Woodpecker Dendrocoptes medius, Lesser Spotted Woodpecker Dryobates minor, Black Woodpecker Dryocopus martius) the publications provides plumage criteria for ageing and sexing, illustrated with graphs and photos. 70 pages.
