I have been fortunate enough to see a real life snowy owl at the Portland Jet Port in Maine. While I do not have a professional camera I had binoculars and was able to see great detail of the owl. I could even she her turn her head as an airplane made a loud sound overhead. The wing span she had was amazing. I call it she because it seems, and I could be wrong that the males have a lot more white than striations on them. She was a good size. The other time I saw owls was in a very icy winter. The Barred owls were starving as they could not break through the ice pack to grab rodents to feed on. I saw one at dusk sitting in a tree by the side of the road. The next day I saw one in my neighborhood and I believe the same one then sat in a tree at the front of my house. They were amazing to see.
