The snow on the side of the road is white, and I can not see far away, the temperature of minus 10 degrees in Calgary, Canada, is very beautiful. The grey owl likes to stand on the green tree trunk. It is hard to see it as one. When you find it, you have to be patient and wait, maybe an hour or more, keep your eyes on it and be aware that it's going to fly at any moment. It's really a test of patience and skill.
