The grey squirrel is a native of North America and was introduced into the United Kingdom. Many people regard the grey squirrel as a pest and there can be no doubt that it’s introduction to this country has led to the decline of the native red squirrel both through competition for feeding (The grey being much more flexible in its requirements) and the introduction of a virus which kills the red squirrel.
But we are where we are. In certain areas of the country, it is possible to manage grey squirrel infiltration to prevent the further loss of the native red squirrel. However in the majority of the country such measures are not possible and so in those areas we might as well enjoy the comical antics of the grey squirrel.
