Hello everyone. Last week I was in the Scottish Cairngorms with my good friends Danny Green and Mark Hancox. This time we were up in the mountains in search of , the Ptarmigan. It was a hard slog as conditions were treacherous. I have the aches and bruises to prove it! More than worth it though just to see this hardiest of birds. The Ptarmigan is possibly Britain's toughest bird species. Perfectly adapted to the harsh cold . In snowy conditions, their feathered feet act as snow shoes, so the Ptarmigan can walk even on soft snow. They are masters of disguise, changing their colour to suit the season. In winter, they go completely white except for a short black tail, their plumage blending in perfectly with the snow making them hard to spot for the Golden eagle that preys on them. They are the only birds in Britain to turn completely white. This wide-ranging gamebird can be found in many of the world's alpine and arctic regions. The mountains of Scotland actually represent the most southern part of its range. Tough old bird. And a lot tougher than me. Respect!
