Stoat or weasel

Three days ago I saw a small creature running across our front porch. When I went to look more closely (having thought it either a rat or a mouse) I found it was either a stoat or a weasel – I really can’t tell them apart. I have never seen one here before. Are they common around the river?

Otter visiting

I think the otter has been visiting our pond again. I think I saw a mink swimming across the pond about a month ago, but now there is a regular track across the field from the river to the pond and evidence of the grass being flattened – similar to the pattern a couple of years ago when the otter was here. Not yet seen any spreint however.
