It is a great shock to see them where you don't expect them, isn't it. They look far too exotic for northern England, or northwest U.S.A. I remember opening my drapes one spring day to see a peacock sitting on my fence. I thought I was hallucinating, so I walked away and then back again. It was still there. When I went out in the garden, I saw another one flying low onto a neighbor's fence. They had escaped from a private park about 7 miles from where I live. Hope that one of them drops some tail feathers as a keepsake.
