There is no bird that only flaps its wings every 3 hours. Because it would not be able to stay up in the sky for those 3 hours. I plumt to the earth everytime. I hope this helped you.
almost all birds
I bird controls its altitude by flying. It flaps its wings to go up, and stops flapping them to go down. Its simple.
Well I can tell you that the average Humming Bird Can flap its wings 50-53 flaps a second so if you times that many flaps to the hour you'll get your answer.
The bird's wings act as an airfoil, as air goes over the wings it creates lift. When a bird flaps its wings the feathers twist in such a way that they catch more air on the downbeat than on the up beat, which creates a net downward force on the air, ans thus an upward force on the bird.
A device to aid lift, such as Slats and Flaps on the wings.
When a bird flaps its wings without taking flight, it typically does so to maintain balance, regulate body temperature, or communicate with other birds. The movement is rhythmic and can vary in speed and intensity depending on the bird's needs.
flaps its wings about 12 times a second.
Hummingbirds beat their wings 70 times per second!
