Obviously, hummingbirds hum, but why? Researchers set out to find the secret behind this mystery and they succeeded.

So, why do hummingbirds hum? Their complex feathered wings produce sound in a similar fashion to buzzing insects due to pressure differences between the tops and undersides of their wings. This is also what allows them to hover so effortlessly.

Scientists believe they can use this information to help make fans and drones quieter.
