I suppose people who live there are accustomed to black squirrels, but I think this is the first time I've ever seen them. Two were darting about on this tree that is close to a roof in Dell Close, Houghton Regis when I spotted them this afternoon.
Another place to look is 'Rabbit Lane', the cycle/footpath that runs from Cemetery Road to Porz Avenue on the western side of Houghton Hall Park. I've seen one there is November 2016, although it scurried away before I could get my camera ready.
