The Lesser Prespa lake, shared between Greece and Albania, is stunningly beautiful when frozen. But alongside our pleasure at such landscapes, are the struggles of animals that have to survive in these harsh conditions. It's all part of nature and the seasons, but that doesn't make it any easier.
Such weather is normal in the high mountains of the Balkans, especially in Prespa at 850m (2,800ft). But this year, unusually, has seen snow and freezing conditions in the Balkan lowlands. Huge parts of the Danube have frozen, as have many wetlands in central Greece. Many wintering birds escape the cold in the north and migrate south to these places, but they are finding snow, not food. Add in bird flu too and, unfortunately, we may see large decreases in numbers throughout 2017.
