Where do birds live?
Highland Perthshire has many tall mountains. There are 28 of the highest 282 mountains here (called Munros).
Not many birds live high up, but in winter there are a few who make it their home.
The Snow Bunting, named after its snowy 'plumage', is a large, arctic bird found in the Highlands.
Snow Bunting's song (click play above)
It's a 'songbird' - like small birds in the garden. It gives the silent, wintery hilltops of Scotland the same sound as a chirpy woodland walk in the summertime.
Outwith this season, Snow Buntings are in Canada, Greenland and Scandinavia.
Birds sometimes change their appearance with the seasons
They are easier to see when in Scotland because their white feathers turn brown in Winter.
Since Scottish winters aren't extremely cold, Snow Buntings can find more seeds and insects in the Highlands than in very cold Canada and Norway.
