I can usually hear a hummingbird before I see it because of the noise of its wings. The hummingbird’s wing beat between 15-80 beats per second, depending on the size of the bird. Most of the North American hummingbirds have a wing beat of around 50 beats per second. Their wings beat in a figure-8 motion which allows them to hover and move in both directions.
It is difficult to stop motion of a hummingbirds wings. I like the blur of the wings – it shows movement.
Here are a few photos of a hummingbird hovering.
