Back home in Chippenham the urban fox's presence has been in sound only. We often hear them barking at night at the moment as it's mating time. It can quite unsettling until you realise what's actually going on. I wonder whether we might have the return of Skimble the Bold sometime soon?
When I lived at home mumble mumble years ago, we found evidence of foxes in the garden, but had no actual sightings back then. A fascinating documentary was shown on the TV around this time highlighting the research carried out by Bristol University which showed just how well the fox has adapted to living alongside us. That research in still ongoing and is accompanied by an excellent website which has lots of information about the study and foxes in general.
BTW the tree immediately behind the fox is one of three trees and shrubs Birmingham Organic Gardeners came and planted in my dad's memory this time 13 years ago. Dad was a founder member of the group and he was very proud of (and amused by) the acronym ;)
