The Llangollen Canal

 Bee fly. I love them.

 Definitely vole feeding. Water vole? Or field vole?

 This burrow is the right size for water vole.

I found myself on a stretch of the Llangollen canal past Ellesemere where I knew there was a history of water vole presence, so I stopped and had a look. The signs weren't quite as definitive as last time, but there were quite a few burrows of the right diameter - think Pringles tube - and some definite feeding. However, it's not just water voles who cut stems at 45%; field voles do too, and there were also field vole burrows. So this is a site to watch, I'd say.
