Yesterday I went out to feed the birds and noticed that there were quite a few holes in the snow, caused by a mammal of some sorts. They led from the pond to the side of the garden where there is only a leaning fence panel - an easy way into the garden for mammals. The holes didn't seem like the ones William made when he walked in the snow, but unfortunately there was a bark path underneath the snow so there were no other clues.
I spent the last 10 minutes listening to the scream of a fox - probably on the field at the back of our garden, although I don't know how far the sound could carry. I'm pretty sure it was a fox after checking what a fox scream sounds like on youtube (can't believe I ever lived without it). I wonder how I can get more clues as to what is drinking at the pond at night. The garden is really muddy, but in the absence of snow I can't really see even the cat prints that I know must be there. Any ideas?
