How Big Is a Hummingbird Heart?

The hummingbird heart is one of the smallest hearts in the world. It is about the size of a pea and weighs only a few grams. The hummingbird’s heart beats very fast, up to 1,260 times per minute.

This is much faster than the human heart, which beats only about 60 to 80 times per minute. The high heart rate helps the hummingbird get enough oxygen to its muscles so it can fly.

The hummingbird is one of the smallest birds in the world, and yet its heart is incredibly big. In fact, it has been said that the hummingbird’s heart makes up almost one-quarter of its total body weight!

This amazing little bird can beat its wings up to 80 times per second, and its heart needs to work overtime to keep up with all that activity.

While we might not think about it often, the size of a creature’s heart really does matter. A bigger heart can pump more blood and oxygen around the body, which is essential for animals that are constantly on the move.

The hummingbird’s big heart allows it to fly long distances and hover in midair for extended periods of time – something that would be impossible if its heart was any smaller.

So next time you see a hummingbird flitting about, take a moment to appreciate all that hard work its little heart is doing!

The average hummingbird’s brain weighs just over 0.1 grams, which is about the same as a grain of rice. Despite their small size, hummingbirds are among the most intelligent of all birds.

They have excellent memories and can remember specific flowers they have visited in the past and how long ago they were there. They can also learn new feeding behaviors from other hummingbirds.

Why Do Hummingbirds Have a Large Heart?

Hummingbirds have a large heart for two reasons. First, their wings flap so rapidly (up to 200 times per second) that they must have a strong cardiovascular system to supply oxygenated blood to their muscles.

Second, hummingbirds consume enormous amounts of energy and must be able to store fat in their bodies to use as fuel.

Their high metabolism and need for quick energy mean that they have one of the highest mass-specific metabolic rates of any animal on Earth.

How Much Does a Hummingbird Heart Weigh?

A hummingbird’s heart can weigh up to 0.11 ounces, which is about 3 grams. The heart rate of a hummingbird is also incredibly fast, up to 1,260 beats per minute!

To put that into perspective, the average human heart rate is only 60-100 beats per minute.

How Much Does a Hummingbird’s Heart Beat?

A hummingbird’s heart rate is among the fastest of all vertebrate animals, reaching up to 1,260 beats per minute when the bird is at rest.

During the flight, a hummingbird’s heart rate can climb to as high as 1,400 beats per minute. To put that in perspective, a human heart typically beats at 60-80 beats per minute.

Hummingbird Body Temperature

Did you know that a hummingbird’s body temperature is about 106 degrees Fahrenheit (41.11 degrees Celsius)? That’s pretty hot! And yet, they are able to fly at high speeds and hover in midair.

How do they do it? It all has to do with their metabolism. Hummingbirds have the highest metabolic rate of any animal on the planet.

This means that they burn more calories per day than any other creature. In fact, they burn so many calories that they have to eat constantly just to keep up with their energy needs. Their high metabolism also allows them to maintain a high body temperature.

This is important because it allows them to fly quickly and perform those amazing aerial maneuvers. If their body temperature was lower, they wouldn’t be able to move as quickly and would become exhausted very easily.

So next time you see a hummingbird zipping around, remember that it’s not just flying…it’s actually running in the air!


The average hummingbird heart is the size of a small bean. It beats at a rate of 1200 times per minute, which is about 20 times faster than the average human heart.

The hummingbird’s heart is so powerful that it can pump blood all the way to its tail!
