Grey squirrels are notorious for displacing red squirrels in European woodlands. They out-compete the native reds for food, feeding more at ground level and being able to digest acorns, which the reds can't. They also carry a deadly pox virus which does not affect them. Grey squirrels were introduced to the UK from the USA in the late 19th or early 20th century. They're now widespread throughout England south of Cumbria and Wales, and common in local pockets in Scotland. They are absent from the rest of mainland Europe, except for small localised populations in Italy.

The eastern gray squirrel or grey squirrel (depending on region) (Sciurus carolinensis) is a tree squirrel in the genus Sciurus native to the eastern and midwestern United States, and to the southerly portions of the eastern provinces of Canada. The native range of the eastern gray squirrel overlaps with that of the fox squirrel (Sciurus niger), with which it is sometimes confused, although the core of the fox squirrel's range is slightly more to the west.
A prolific and adaptable species, the eastern gray squirrel has been introduced to, and thrives in, several regions of the western United States. It has also been introduced to Britain, where it has spread across the country and has largely displaced the native red squirrel, Sciurus vulgaris. In Ireland, the red squirrel has been displaced in several eastern counties, though it still remains common in the south and west of the country. There are concerns that such displacement might happen in Italy and that gray squirrels might spread from Italy to other parts of mainland Europe.
