[i]Mustela nivalis[/i]
This is probably my favourite shot of this recent South-east England trip.
My first time seeing our native weasel as anything other than a fast-moving blob in the car headlights. Was a good bit of timing on my part as it turned out - they'd just been fed and were busy bringing home the bacon, as it were. These glass-windowed burrows are very handy for giving a view of what would otherwise be a very difficult species to view.
