Animals ranging from the red squirrel to the capercaillie grouse are also depicted, as part of an effort to show the importance, and precariousness, of the natural world.

They provide habitat for red squirrels and birds such as capercaillie, crested tits and crossbills.

Most capercaillie are found in the Cairngorms National Park.

Cairngorms is the largest national park in the UK and home to 25% of all threatened and rare species, such as capercaillie and golden eagles.

The capercaillie is a native species that became extinct in Britain in the mid-18th Century.
