It is flapping wings.
When an insect flies, the size of its wings and the speed of their flapping affect the sound they make.
Um, a flapping sound?
The speed of the bee's wings produces a 'hum' which falls within the range of our hearing. The crow's wings do produce a 'note' but it's too low for our ears to detect. Human hearing range falls roughly between 20 Hz and 20,000 Hz,
that sound comes from them flapping their wings rapidly
that would be the wings, like all flying insects that make a buzzing sound.
The high speed flapping of their wings makes a vibration sound that is the 'buzz' that you can hear.
Because it didn't know the words? They don't hum. Their wings are making the humming sound. The hummingbirds chirp.
