| Résumé : | Until 2012, the Middle-spotted Woodpecker was almost absent as a breeding bird in the northernmost part of Schleswig-Holstein (N Germany). In 2014 and 2015, 48 territories found in 15 forests gave evidence for a strong increase, indicating a rapid northward expansion towards the German-Danish border. Most likely, Denmark will be colonized soon, following the disappearance of the species in the 1950s. |
