This misty morning, after surveying the copious evidence of someone’s haze-inducing, lager session at the viewing shelter, I was walking back to along on Buddleia Trail to fetch a rubbish bag when I spotted a movement way ahead on the path. The brown critter scurrying across into the border at first made me think “rat” for a millisecond, until I realised it was much more slender and nippy. Armed with neither my spectacles nor binoculars I froze and waited. To my surprise it re-emerged and continued its frantic exploration of the margins and hedges, zapping from one side of the path to the other, all the while getting closer. A weasel!

As the wrens voiced their protest to this unwelcome visitor it got to within about 20ft of me before diving into the scrub. My optimism that it might re-emerge even closer wasn’t to be rewarded, but as I resumed my way down the path a check behind me yielded one last glimpse a few yards up the path.
