No trip to Northumberland would be complete without Red squirrels, so here's one for you, gnawing on a pine cone of some sort. Actually this squirrel is caged at Thorp Perrow Arboretum (which is in North Yorkshire, as has been pointed out to me) and photographed through the mesh as described in my previous post. I did see a few in the wild but they were too quick for me this year. I did notice that they seemed more deeply coloured, with notably blacker tails than the ones I had seen last year, which may be meaningful in some way but is probably just natural variation or dodgy memory.
