It’s in their very name– hummingbirds make a humming sound! In addition to making high-pitched, chirpy tweets, these birds beat their wings so rapidly that it produces a buzzing noise that almost sounds like a bumblebee. On the Arizona Sonora Desert Museum’s website, you can listen to the sounds of the metallic green Anna’s Hummingbird. These little creatures are only four inches long and weigh as little as a tenth of an ounce, but they still play an important role in their ecosystem– the Anna’s Hummingbird eats more insects than any other North American hummingbird!
