Red squirrels have been edged out of most of Britain, displaced by greys originally from north America. They are still in Scotland, on Brownsea Island in Portland bay, on the Isle of Wight and the Isles of Scilly. And, of course, on mainland Europe.
That’s where we saw this one, in the gardens of the Alhambra Palace in Granada (a long time ago). It was yet another squirrel which was used to being fed, and came closer rather than fleeing when people were around.
