While I was photographing this bird he seemed to like to show off for me, jumping around in the snow, while I took pictures from about 50 feet away. I think must have gotten annoyed with me because suddenly he charged toward me, taking flight, while I continued shooting. This photo shows him flying right towards me. He veered off when he saw I wasn't going to run but I was able to get this photo. Camera settings were, continuous focus and shutter, 1/1250 sec., f/8, and 650mm focal length, ISO 400..
