Hummingbirds Fly and Feed Inside a Wind Tunnel While Being Filmed by a High-Speed Camera
The latest episode of the series Deep Look by KQED and PBS Digital Studios features slow-motion video of hummingbirds flying and feeding inside a wind tunnel. The experiment shows how hummingbirds use their wings differently than most birds to be able to hover in one place to eat, even in the rain and wind up to 20 miles per hour.
They have to. Because of their high metabolism, hummingbirds have to eat their own weight in flower nectar every day.
