I have had three interesting encounters recently.
Yesterday, descending through Winterseeds farm, I was swooped several times by a bird I never saw. I had my cap on to keep the sun out of my eyes, and the brim did not help my powers of observation.
The last time I came off Fairfield there was a Highland Longhorn on the path - I know thy are docile but I still chose to go around it. Lower down there was a goat and its kid - initially they moved away, but then the mother turned and stood her ground - again, I chose to give her a wide berth.
