After taking this photograph this male snowy owl became irritated with me being too close and watching him. He later flew off, did a circle, then came back and buzzed my head, I was totally surprised at his behavior. These birds hunt at night and try to sleep during the day. People interrupt their sleep and they can get irritated if bothered.
Taken with my Canon EOS 5D MII, with 400 mm lens.
