Hhhmz! A hummingbirds flew past me while I was in the garden and yet, it still managed to halt perfectly in front of a blooming flower nearest to me. Just as soon I began to wonder, how fast do hummingbirds fly and in which way do they achieve their flight in addition to their distinctive hum.
Hummingbirds can give the impression by their small body size that they are very fast and of course they are. The Anna-Hummingbird, about ten centimeters in size, reach speeds of 385 body lengths per second (27. 3 m/s or 98 km/h). So they can get acceleration values of about ten times the acceleration due to gravity.
To the comparison: Peregrine falcons come on speeds of up to 200 body lengths per second in the nosedive and fighter jets, like e. g. the MiG-25 (a Mach 3 fast interceptor), reach only the approximately by 40 times of its total length by one second.
They got this enormous achievement mostly by their biological construction.
For example: the heart of the hummingbird is very large in relation to the body and beats 400 to 500 times per minute, its respiratory rate is up to 250 strokes per minute, so lots of oxygen gets into their wings and they can perform so strong. During sleep, many hummingbirds reduce their heart rate to save energy.
