With the ability to fly the distance than 385 times in body length per second, hummingbirds are thought to move the fastest animal on earth.

Hummingbird is a family of small birds living in North America. When flying they can stand still a place beats off frequency up to 70 times per second. This is the only birds on the planet capable of flying backwards. Than 300 species of hummingbirds eat nectar. They owned the mine to a length of 10 cm deep into paddy many flowers. Tongue of hummingbirds also quite long so they can smoke nectar. They can be standing still a space flight, flying back and keep the bird fixed. They usually fly at a rate of approximately 50 km/h. The breeding season the males have done lots of diving down to charm the birds.

Experiments show that male hummingbirds can reach speed 92.8 km/h as they dive from a height of 30 meters to impress the birds. Because the average body length of 10 cm of hummingbirds so with that speed, every second they are flying distance than 385 times the length of the body.

Meanwhile, a jet fighter plane was flying distance than 150 times per second when the body length of up lick. Shuttle spacecraft flight distance than 207 times the length of body when they returned to earth. In the course of the dive, hummingbirds suffer great force 10 times Earth’s gravity. Even the pilots of fighter jet machine experienced vomiting when one must also suffer the same force with magnitude
