I have enjoyed many sightings fishing, short eared owls quartering a field once, and a hobby hunting right close to me, they stick in the mind a bit. Favorite bird is difficult. I have also always wanted to see a Hoopoe and I have a nice illustration on one of my prints By Archibald Thornburn, a Victorian painter of wildlife, the best in my opinion but George Lodge of the same area comes close so, always hankered to see one in the flesh. Favorite bird, they all bring a little diversion on a fishless day except sea gulls, they divert me to madness but even then I have an admiration for them, adapters and survivors first class.
I will opt for the Robin, always a joy wherever or whenever you see them.
