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. 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. I saw this skiddish little guy peaking from a hole in a dead tree in an empty lot in Rockaway, NJ USA. I used my Nikon D3100 and 70-300mm zoom lens.
