How is a humming bird like helicopter?
Both hummingbirds and helicopters use rapid wing flapping to generate lift and stay in the air. Hummingbirds flap their wings at an incredibly high frequency, up to 80 times per second, while helicopters rotate their rotor blades at high speeds to achieve the same effect. Additionally, hummingbirds and helicopters can both move in multiple directions and hover in place, displaying remarkable maneuverability.
