While hummingbirds are the fastest animals on Earth relative to their body size, outpacing fighter jets and the space shuttle, they do not break the sound barrier. The sound barrier is 767 mph, which is more than three times the speed of the Peregrine Falcon, the fastest bird, which can dive at up to 240 mph. To break the sound barrier, a bird would need to be selectively bred to withstand extreme g-forces and have its circulatory system overhauled, which is not possible in nature. However, male hummingbirds do make high-speed dives to impress females, producing a loud, brief chirping sound.

What You'll Learn
The fastest animals on Earth relative to their body size
While no bird has been observed breaking the sound barrier, hummingbirds are the fastest animals on Earth relative to their body size. They can cover more body lengths per second than any other vertebrate and can even outpace fighter jets and the space shuttle. They also withstand g-forces that would make the average human black out.
The male Anna's hummingbird, in particular, performs impressive high-speed dives as part of its courtship ritual. Its maximum dive speed of 385 body lengths per second is faster than peregrine falcons (200 blps) and swallows (350 blps) diving in pursuit of prey. It is also greater than the top speed of a fighter jet with its afterburners on (150 blps) or the space shuttle during atmospheric re-entry (207 blps).
The speed of the male Anna's hummingbird dive generates a loud sound, and during the dive, the male spreads its outer tail feathers, which vibrate like the reed of a clarinet, producing a loud, brief chirping sound.
While hummingbirds are the fastest animals relative to their body size, it is worth noting that the peregrine falcon is the fastest bird in terms of pure speed. The peregrine falcon can dive at up to 240 mph, an astonishing feat that showcases the incredible capabilities of these birds.

Faster than fighter jets
While hummingbirds are incredibly fast, they do not break the sound barrier. The sound barrier is 767 mph, and the fastest hummingbirds only reach speeds of 385 body lengths per second (blps). To break the sound barrier, a hummingbird would need to be more than three times faster than the fastest recorded hummingbird.
However, hummingbirds are still incredibly impressive when it comes to speed. They are the fastest animals on Earth relative to their body size. They can cover more body lengths per second than any other vertebrate. In fact, their maximum dive speed of 385blps is faster than peregrine falcons (200blps) and swallows (350blps) diving in pursuit of prey.
The speed of hummingbirds is so remarkable that they are even faster than fighter jets relative to their size. The top speed of a fighter jet with its afterburners on is 150blps (885 meters per second), while the space shuttle during atmospheric re-entry reaches 207blps (7,700 meters per second). Both of these speeds are slower than the maximum dive speed of a hummingbird.
The speed of hummingbirds is not just impressive for their size, but also in terms of the g-forces they can withstand. Hummingbirds can withstand g-forces that would make the average human black out and even cause a fighter pilot to black out. This makes them not only faster than fighter jets in terms of speed but also in terms of the forces they can endure.

Withstanding g-forces
While hummingbirds are incredibly fast, they do not break the sound barrier. The sound barrier is 767 mph, and the fastest hummingbirds can only reach a maximum dive speed of 385 body lengths per second (blps). This speed is faster than peregrine falcons (200blps) and swallows (350blps) and is also greater than the top speed of a fighter jet with its afterburners on (150blps) or the space shuttle during atmospheric re-entry (207blps). However, it is still far below the speed of sound.
Despite not breaking the sound barrier, hummingbirds are still incredibly impressive when it comes to withstanding g-forces. Due to their small size, hummingbirds can withstand g-forces that would make the average human black out. In fact, their dives can generate g-forces similar to those experienced by fighter pilots, which is why they are sometimes said to "outpace fighter pilots."
The ability of hummingbirds to withstand high g-forces is due in part to their small size. Smaller objects experience less air resistance and therefore generate less heat when moving through the air. As a result, hummingbirds can maintain their speed and maneuverability even while experiencing high g-forces.
In addition to their size, hummingbirds also have several anatomical and physiological adaptations that allow them to withstand high g-forces. For example, they have a unique skeletal structure that is both lightweight and strong, with a high bone density that helps to reduce the impact of g-forces on their bodies.
Hummingbirds also have a very efficient respiratory system that allows them to take in enough oxygen during high-speed dives, even while experiencing high g-forces. Their wings are also specially adapted for high speeds, with a high aspect ratio and a flexible wing design that allows them to adjust their wing shape and angle to maximize lift and minimize drag.
Overall, while hummingbirds do not break the sound barrier, they are still incredibly fast and agile creatures that can withstand g-forces that would be dangerous for larger animals.

High-pitch sounds for communication
While hummingbirds do not break the sound barrier, they are known for their ability to produce and hear high-pitched sounds that are beyond the range of most birds. This unique capability plays a crucial role in their communication and social interactions.
The Ecuadorian Hillstar (Oreotrochilus chimborazo), a hummingbird species inhabiting Andean high-altitude grasslands, showcases the most complex high-frequency (HF) vocalizations among hummingbirds. Their song has a fundamental frequency of 13.4 kHz, surpassing the range of 2 to 8 kHz typical for most birds. This exceptional ability to produce high-frequency sounds may offer the Ecuadorian Hillstar a private mode of communication in their crowded forest habitat.
The Black Jacobin hummingbird, native to Brazil's Atlantic Forest, also boasts the highest-pitched call of any bird. Its song is so high-pitched that it eluded detection by researchers, requiring specialized equipment designed for capturing ultrasonic bat calls to be recorded successfully.
The ability to produce such high-frequency vocalizations suggests that these hummingbirds may possess specialized vocal cords. However, it remains uncertain whether they can hear their own high-frequency calls. While some owls are known for their ability to hear high-frequency sounds for hunting, the HF song of the Ecuadorian Hillstar serves a different purpose—conspecific communication.
Research has shown that the O. chimborazo hummingbirds exhibit behavioral and neural responses to the playback of HF songs. They alter their body posture, approach the source of the song, and show territorial behaviors. These responses indicate that they can, indeed, hear frequencies above 10 kHz, enabling them to utilize their HF song for communication and social interactions.
In summary, while hummingbirds do not break the sound barrier, they are remarkable for their ability to produce and perceive high-pitched sounds that facilitate their communication and social behaviors. This unique adaptation allows them to thrive in diverse ecological niches, ensuring their survival and reproductive success.

The sound barrier speed
The sound barrier is a speed of 767 miles per hour, which is incredibly fast and challenging to reach. To break this barrier, an object must travel faster than the speed of sound, which creates a sonic boom. While hummingbirds are incredibly fast relative to their body size, they do not break the sound barrier.
Hummingbirds are the fastest animals on Earth for their size. They can cover more body lengths per second than any other vertebrate. They can even outpace fighter jets and the space shuttle relative to their size. Male hummingbirds perform high-speed dives as part of their courtship rituals to impress females. These dives produce a loud, brief chirping sound. The maximum dive speed of a hummingbird is 385 body lengths per second, which is faster than peregrine falcons (200 blps) and swallows (350 blps).
The speed of sound is incredibly fast and requires more than just aerodynamics to break. To reach this speed, an object must also have the circulatory system and endurance to withstand the g-forces that come with it. Additionally, the altitude required to reach these speeds poses a challenge for birds, as they need air density for flight.
While hummingbirds are incredibly fast and agile, they do not come close to breaking the sound barrier. Their speed relative to their body size is impressive, outpacing many other birds and even aircraft. However, their small size also limits their overall speed, and they are unable to reach the speeds necessary to break the sound barrier.
The ability to break the sound barrier is an intriguing concept, and while hummingbirds do not achieve it, they are still remarkable in their speed and agility. Their courtship dives showcase their speed and produce loud sounds that are an essential part of their mating rituals.
