<br /> <p>Hummingbirds are well known for having wings that move so fast that the human eye can hardly see. Greg, who recorded this video, had been trying for ages to get a close up shot of one of these birds on the move. He set up his GoPro beside a feeder and eventually got the footage he wanted. This video slows the images in slow motion so the viewer can see each wing flap. Credit: Facebook/Greg Hogan</p><br />
