Amazing Hummingbird Stunts
The dives that male Anna’s hummingbirds (Calypte anna) perform during courtship dances are some of the most astounding in the animal kingdom. At their peak speed in the dive, they are traveling at 61 miles per hour. Adjusted for body length, this makes them the fastest bird on Earth. Even more astonishing is the maximum g-force they reach in pulling up out of their dives. According to new research, they experience more than 9 times the force of gravity, a number that can cause human pilots to blackout. For more information on this study, see ScienceNews.
