Eagle, certainly not a tortoise!
I got up to 3 brown hares in the field next to the cottage. Two were leverets just running around together. The other was a watchful parent, who seemed to shepherd them at times.
Then the golden eagle returned yet again yesterday afternoon and ate something just on the hill behind. It stayed for quite a while again, which seems to be a habit.
Later yesterday, as I was enjoying the evening sunshine, I opened the back door and there was a hare just grazing, in the shadow of the cottage.
