Rodent dinner table

I cleared a pile of logs that had been drying on the terrace only to find that it has clearly been used by some rodent or other as a place to take nuts and shell them, leaving gnawed husks aplenty. I suspect it's one of the bank voles we often see dashing across from hedge to hedge.A reminder that leaving things alone in the garden is a sure way of encouraging wildlife.  Our piles of logs and clumps of weeds quickly become valuable habitat and shelter for something.
