Ruth we mainly have grey squirrels so a red one spotted is a great find. They thrive in Scotland as there are lots of pine forests up there.. The Grey has long been blamed for the decline of our Red squirrel but this is not so.Grey Squirrels don't chase Red Squirrels away. It is simply a gradual ecological replacement due to Greys being more adaptable. Plenty of evidence shows the two species living together for significant periods.
