When the humming- birds hover over the flowers to suck their nectar, their wings have to flap as fast as 50 times per second to maintain their posi- tion. The beating of their wings at such a speed produces a faint humming sound. That is why these birds were given the name hum- mingbirds, although they do not actually hum from their mouths.
How did the Hummingbirds get their name?
