In various parts of the opposite end of England, red squirrels hang on, though beleaguered by the advancing greys. Have noticed road signs in various spots in the part of Cumbria which used to be Westmorland: intended to alert motorists to red squirrels' being around, and to request them to try not to run them over. One such which I observed, read "Caution -- red squirrels": thought that wording perhaps a little unfortunate -- visitors not au fait with Britain's squirrel situation, might misinterpret such a sign along lines of "they can be vicious little brutes -- beware !"
