Stones of Stenness and a sheep

I heard there was an osprey hunting around the Loch of Harray so headed out there. Didn't see it. As I walked up to the dig at the Ness of Brodgar, however, a hobby flew fast and low past the viewing stand and then over and beyond the nearby bungalow. I thought it was a hobby immediately but didn't see the red feathering around the legs as it went by. Checking a BTO ID video on the internet later, it turns out that juvenile birds at this time of year don't have the redness. I had a look at the dig and then walked around the RSPB reserve before the wind and rain came on and made me head for home.  This sheep is a Texel. I always think they resemble the Mitchell brothers from Eastenders. What do you think?
