How do you describe the sound a hummingbird makes? This is somewhat difficult to do, but the sound a hummingbird makes isn’t a true “song.” Hummingbirds will vocalize by making chirping notes. The call of a hummingbird is made up of a series of short buzz trills and chirps. Hummingbirds’ wings ‘buzz’ or make a whirring sound while the birds are in flight. This sound is referred to as a "wing whistle." The hummingbird will frequently vocalize in effort to attract a mate.
