out of place animal?

Well I know the climate is changing but didn’t think it was that warm:

A couple from Cornwall have photographed a prairie dog while they were on a moor in Cornwall. Linda and Godfrey Stevens were on the Goss Moor trail when they spotted a small furry creature that they could not recognise. Godfrey Stevens said: "We didn't expect to see anything like that." Newquay Zoo confirmed the picture was that of a prairie dog. They are mammals from the squirrel family and are from the grasslands of North America. Mr Stevens said: "We expected to see wild flowers. It was a real surprise for us." John Meeks from Newquay Zoo said it was a black-tailed prairie dog "without a doubt".
