Interestingly, they are incredibly territorial, and you will often hear them battling with other hummingbirds.īelow, you will learn how to identify the CALLS, TWITTERING, and HUMMING of a Ruby-throated Hummingbird ( Archilochus colubris). Other body parts of the hummingbird, specifically the tail, also influence how the humming sounds to humans.Despite their small size, Ruby-throated Hummingbirds make a variety of calls and sounds. This is because it is not only the wing movement that creates the hum. The unique flight of hummingbirds is what allows them to hover mid-air with minimal vertical movement.Īlthough all hummingbirds have the hovering in common, the humming sound has more variation. Scientists have not discovered a specific purpose for the sound yet but the wing movement does serve an essential purpose. Specifically, it is a combination of their u-shape motion and rapid flapping that creates the distinct sound. The recognizable hum of hummingbirds is an effect of how they move their wings. The faster wing movement allows for less vertical movement which makes it easier to suck nectar out of flowers. Hummingbird flap their wings very rapidly so that they can stay in place. Why Do Hummingbirds Flap Their Wings So Fast? Essentially, they may buzz around you because they recognize you as a food source. If you feed them regularly they will start to recognize that you are the bearer of more food. Hummingbirds are quite intellectual birds.
The humming sound is created by their specific wing motion shape, frequency and aerodynamics. Hummingbirds don’t create a buzz like bees but rather a hum, hence their name. Frequently Asked Questions: Do Hummingbirds Make a Buzzing Sound? Perhaps in the future, a more natural wing motion could make drones less noisy. By examining the aerodynamics of hummingbird flight, they might come up with a solution to help drones fly more quietly.Īt this moment, drones are so loud because it creates the same wing movement as helicopters. The scientific research team that discovered the exact source of the hummingbird sound also came to a different conclusion. This is very similar to how a hummingbird hovers, except they do it while flying in the air. In contrast, faster arm and leg movement makes it feel like you are bobbing less in the water because you are counteracting the force of gravity. The slower you move, the more noticeable the bobbing up and down in the water. This extremely rapid motion is what lets them hover to suck nectar from flowers. Hummingbirds can flap their wings anywhere between 20 – 80 times per second, unrivalled by other bird species. However, there is an important evolutionary function to their rapid wing movement. So far, it seems that the sound of a hummingbird is just a byproduct of their movement. This helps to explain the different hummingbird flight sounds. Compare the different sounds you get when moving a paper fan versus a long ribbon through the air. For example, Anna’s Hummingbirds have a shriller sound than Scissors Tail Hummingbirds.Īnna’s Hummingbirds have shorter broad tails that open like a fan while the Scissors Tail Hummingbirds have long thin two-pointed tails. The shape of the hummingbird tail also affects the sound that we hear. This is because the wings are not the only thing that creates a sound. Do All Hummingbirds Sound the Same?Īlthough the general wing movement is almost identical in all hummingbird species, the exact hum timbre may differ per species. Hummingbirds move their wings in a u-shape which creates the sound frequency between 40 Hz – 80 Hz that is pleasant to human ears. This is because of the different movement patterns. After all, many flying insects flap their wings much faster but are known for very different sounds compared to the hummingbird. The rapid wing flapping is not the only reason for the hum, though. It is this difference in pressures that develops the characteristic hum. Unlike other bird species that build lift only once per wingbeat, the hummingbird is capable of creating lift twice per wingbeat. At most, you hear a slight whooshing sound which is the sound of air lifting them up. Most birds are virtually silent in flight and this is also because of the aerodynamics of their wings. How high pitched that buzz sound is depends on how fast or slow they flap their wings. Each specific wing shape and movement pattern creates a different sound.įor example, mosquitoes and flies create a buzzing sound. Like with most birds and insects, the sound that we hear flying around us is the sound of their wings.
What Part of a Hummingbird Makes the Humming Sound? As of yet, it is still unclear whether the sound serves a function in itself but we now know what exactly creates the hum. The humming sound of hummingbirds is created by the distinct movement of their wings. Why Do Hummingbirds Make a Humming Sound?
