We still have red squirrels here in Donegal. Don't ever recall seeing any greys, but I'm sure someone will correct me. It's one of their last strongholds in these islands. Greys simply don't belong here - vermin. North America, fine, British Isles not good. They out compete the native reds, and carry a disease to which they are immune, but is fatal to reds. That definitely makes them unwelcome in my estimation.
