Grey Squirrel (Sciurus carolinensis)

The grey squirrel was introduced to this country at the beginning of the 20^th century and is abundant. You’re unlikely to walk through any park or wood without seeing one especially in the warmer months. They don’t hibernate but are less active in the winter. They are larger than the native red squirrel and better adapted to modern surrounding unlike the red squirrel that stick to the treetops in forests and woods solely. They are born bald and with their eyes closed. In forests where they are too abundant they can have a really negative effect on the trees, stripping the bark. They can live up to 20 years.
