Lake Kerkini in Greece is one of the most beautiful birding sites in Europe, offering visitors an unparalleled diversity of colours. This protected national park has always been the scene of unique interactions between birds from all over the Mediterranean and its abundant diversity has given rise to a unique spectacle: collective hunts, often gathering more than a thousand birds of a dozen different species. But the surrounding forest, now threatened, predicts a new change for this lake and its feathered inhabitants.
