Photo by @anandavarma. Water vapor from a fog machine helps visualize the air flow around a hovering Anna’s Hummingbird. Those whirlpools of air you see on each side of the bird are called wingtip vortices and they are generated with each flap of the hummingbird’s wings. By visualizing the aerodynamics of hummingbird flight, researchers are able to better understand how these tiny birds are able to stay aloft. Check out today’s instagram story to see these birds in slowmo or check out my feed to see more images from the story that is out in the July issue of the magazine.
