how fast do hummingbirds wings beat per minute
Hummingbird They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species, to in excess of 80 in some of the smallest. Of those species that have been measured in wind tunnels, their top speed exceeds 15 m/s (54 km/h; 34 mph) and some species can dive at speeds in excess of 22 m/s (79 km/h; 49 mph).[1][2]
Fastest animals The fastest land animal is the cheetah, which has a recorded speed of 109.4–120.7 km/h (68.0–75.0 mph).[1] The peregrine falcon is the fastest bird and the fastest member of the animal kingdom with a diving speed of 389 km/h (242 mph).[2] The fastest animal in the sea is the black marlin, which has a recorded speed of 129 km/h (80 mph).[3]
