A red squirrel avoiding the crowds.

Seen near the Scottish Perthshire village of Killin. This is a rare sight for me living much further south in England, as the much more aggressive grey squirrel dominates and have made the reds almost extinct in England. This was seen scampering under a bridge that I was stood on trying to catch images of the river.
Sciurus vulgaris: Due to their overall population declines, red squirrels are classed as endangered on The Mammal Society's Red List for Britain's Mammals. Scotland supports 75% of the UK population, yet even here they are classed as near threatened.
