I am just filled with awe after watching this:
Space may be the final frontier, but scientists have found plenty of head-scratchers right here on one of Earth’s zippiest creatures, the humble hummingbird. The July issue of National Geographic Magazine includes stunning photography by Anand Varma of ornithologist Christopher Clark’s experiments studying how the Anna’s hummingbird sees, moves, and eats.
Clark recreated studies from UC Berkeley and the University of British Colombia that use smoke, optical illusions, and specially-created tools in conjunction with high-speed cameras to reveal hummingbirds’ strange body parts. For example, the reason they can hover is because their unique bone structure allows them to create lift on the upswing, as well as the downswing of their wings.
You can see and read more about this at The Creators Project. I might have to put that video on a loop.
