The red squirrel has a typical head-and-body length of 7 + 1⁄ 2 to 9in), a tail length of 15 to 20cm (6 to 8in), and a mass of 250 to 340g (9 to 12oz). Males and females are the same size. The Eurasian red squirrel is somewhat smaller than the American eastern grey squirrel, which has a head-and-body length of 25 to 30cm (10 to 12in) and weighs between 400 and 800g (14oz and 1lb 12oz).

The red squirrel or Eurasian red squirrel ( Sciurus vulgaris) is a species of tree squirrel in the genus Sciurus common throughout Europe and Asia. The red squirrel is an arboreal, primarily herbivorous rodent. When winter's fresh food shortages arrive, squirrels will locate and use up most of their stored supplies, but they won't find them all again. This inadvertently benefits the next generation of squirrels, as these buried seeds stand a chance of growing into new trees that produce new sources of food. Where do squirrels live? Sidorowicz, J.
