Is it true that the hummingbird's wings beat 320 times per minute?
assistant
Yes, the hummingbird's wings beat at a rate of about 320 beats per minute. The average hummingbird has a wing span of 4-5 inches and weighs 0.2 ounces. A hummingbird can fly up to 20 miles per hour. So its wings are able to beat fast enough to keep up with its speed.
