Squirrel Nation is a history of Britain's two species of squirrel over the past two hundred years. The red squirrel, although rare, is among the most cherished of native species. Grey squirrels, by contrast, are one of the most frequently seen wild creatures in our gardens, parks, towns and countryside, and many Britons consider it to be a foreign interloper, introduced from North America in the late nineteenth century. By examining this animal's colonization of Britain, Peter Coates also explores timely issues of belonging, nationalism, citizenship and the defence of borders within Britain today. Ultimately, though people are swift to draw distinctions between British squirrels and squirrels in Britain, Squirrel Nation shows that Britain's two squirrel species have much more in common than at first appears.
