Highland cattle are of course a domestic breed but the goats I saw on my previous lochside walk up near the north end of the loch are feral, there seems to be quite a healthy thriving population and are a common sight for walkers on the West Highland Way.
The next photo was taken rather quickly of an unknown creature in the water. It took a bit of time to realise we were watching a mink swimming just off shore carrying dead prey which appeared to be only slightly smaller than the mink itself. After swimming, the mink scampered across the beach and headed behind rocks to better cover. American mink have no natural predators, save man, in this country and are a result of the generations following escapees from mink farms as far back as the 1920s. The mink population have become a nuisance in parts but I was intrigued to watch it as I've never previously seen one.
