grey squirrel

This is the grey squirrel or Sciurus carolinensis, which in Europe

is considered extremely destructive to native trees and the only native squirrel species, Sciurus vulgaris [the Red Squirrel].  The Grey Squirrel has made it to the Invasive Species Specialist Group of the World Conservation Union’s list of “100 of the World’s Worst Invasive Alien Species.”  British and Italian environmental groups have ranked the Grey Squirrel as second in negative impact only to the Norway rat (Rattus norvegicus).

The Grey Squirrel may be carrying a virus which is deadly to the red squirrel, but harmless to the grey. That said, it out-competes the red squirrel for food, and is damaging to trees as it can strip them of their protective bark, exposing them to disease. Grey squirrels feed on nuts, flowers, fruits, seeds, tree bark, fungi as well as bird eggs, nestlings and frogs.
