4) Grey Squirrels

Grey squirrels, like they're cousins the red squirrels, are mammals. They also make drays. They originally come from North America. They have pushed the reds up north, poor reds. Grey squirrels are greyish in colour, usually with reddish heads. They are very similar to red squirrels, so, to find out more, use the red squirrel fact file.
