Bee Hummingbird, the tiniest of all and native to Cuba and the Isla de la Juventud, this little bird weighs only about 1.95 grams (0.068 ounces) whereas Giant Hummingbird species weighs approximately 18-24 grams (0.63 – 0.85 ounces)

Hummingbird Species and Weight Variation

There’s a noticeable variation in weight among different species in the world of hummingbirds. As you explore these fascinating creatures, you’ll discover the smallest and largest species and their weights.

Smallest Species

Meet the Bee Hummingbird, the tiniest of all! Native to Cuba and the Isla de la Juventud, this little bird weighs only about 1.95 grams (0.068 ounces). To put things into perspective, that’s roughly the weight of a small paperclip. These minuscule creatures truly live up to their name, as they’re often mistaken for bees.

Largest Species

On the other side of the scale, you’ll find the Giant Hummingbird. This species weighs approximately 18-24 grams (0.63 – 0.85 ounces) and is mostly found in the Andean highlands, spanning from Colombia to Chile. While still tiny compared to other birds, the Giant Hummingbird is noticeably heavier than its smaller counterparts.

As you can see, hummingbirds are fascinating creatures with significant weight variation across species. Keep exploring, and you’ll find countless more interesting facts about these extraordinary birds!

Factors Affecting Weight


Your hummingbird’s weight will be greatly influenced by its diet. These tiny birds consume many nectar, insects, and spiders to meet their high energy demands.

A diet rich in nectar provides quick energy from sugar, while insects and spiders offer necessary protein and fat. You may notice fluctuations in your hummingbird’s weight based on their environment’s availability and variety of food sources.


Their weight will change as hummingbirds develop from hatchlings to mature adults. Young birds will likely weigh less than their adult counterparts as they continue to grow and develop.

This weight difference may not be significant, but keep in mind that healthy growth and development are essential to the overall well-being of your hummingbird.

Mating Season

During the mating season, you may observe a change in your hummingbird’s behavior and weight. Males, in particular, will engage in impressive aerial displays and frequent feeding in an attempt to attract a mate. These energy-intensive activities could lead to some fluctuations in their weight as they consume more food to fuel their efforts.


Finally, migration can have a significant impact on your hummingbird’s weight. The birds will build up a layer of fat before embarking on their long journey to have a sufficient energy reserve. This extra fat increases their body weight by a considerable amount.

Once they arrive at their wintering grounds, they may lose some of this excess weight. Remember, these natural fluctuations are essential to their survival during these challenging times.

Weight Measurements

When you want to measure the weight of hummingbirds, you’ll find that these tiny creatures are incredibly lightweight. In fact, their weight can range anywhere from 2 to 20 grams, depending on the species.

You might be surprised to learn that some hummingbirds, like the smallest species, the Bee Hummingbird, weighs only around 2 grams. This little bird might even weigh less than the weight of a penny!

On the other hand, the Giant Hummingbird, which is the largest species, can weigh up to 20 grams. To help you visualize this, a 20-gram hummingbird is about the same weight as four nickels.

One key factor that affects a hummingbird’s weight is its metabolism. These fast-flying birds have very high metabolic rates, requiring them to consume much nectar, insects, and spiders daily. Their bodies need the energy to sustain their rapid wing flapping and hovering capabilities.

Here’s a quick comparison of some common hummingbird species and their weights:

  • Bee Hummingbird: 1.95 – 2.6 grams
  • Ruby-throated Hummingbird: 2.5 – 3.5 grams
  • Anna’s Hummingbird: 4.3 – 4.6 grams
  • Black-chinned Hummingbird: 3 – 4 grams
  • Giant Hummingbird: 18 – 20 grams

Keep in mind that these weights can vary due to factors such as age, sex, and nutritional status. Hummingbirds can adjust their body weight seasonally, adding a little extra fat during migration to ensure they have enough energy for the journey.

In conclusion, the weight of a hummingbird is astonishingly low, which adds to their mystique and allure as one of nature’s captivating creatures. Now you better understand how much these spectacular birds weigh, and you can appreciate their unique adaptations even more.


Why Weight Matters?

Energy Expenditure

Weight plays a crucial role in the energy expenditure of hummingbirds. Due to their exceptional metabolism, hummingbirds need to consume a significant amount of nectar daily to fuel their high-energy lifestyle. A lower weight translates to reduced energy requirements, and that’s why your little friend’s weight is so important.

Keeping their weight in check allows these fascinating creatures to balance the energy they consume and energy stored. This balance lets them stay active, visiting up to a thousand flowers daily to satisfy their hunger.

Flight Abilities

Another reason why weight matters for hummingbirds is its impact on their flight abilities. With their hovering and rapid maneuvering, it’s no surprise that a lightweight hummingbird would have improved flight capabilities. Lower weight increases their agility and maneuverability, making it easier for them to zip around and evade potential predators.

The ability to move quickly also benefits them during their long-distance migrations. Hummingbirds embark on impressive journeys, with some species flying thousands of miles. A lower body weight makes these treks more manageable by reducing the energy demand required to maintain flight.

As you can see, weight significantly impacts a hummingbird’s lifestyle, from energy expenditure to flight abilities. So the next time you spot one of these fascinating creatures, remember how their delicate balance of energy and weight enables them to thrive uniquely.

How Much Does a Hummingbird Egg Weigh?

When you’re looking at a hummingbird, it’s hard to imagine just how tiny and delicate its eggs must be. Considering their diminutive size, you might wonder how much a hummingbird egg weighs. Let’s take a closer look.

Hummingbird egg weight: A hummingbird egg typically weighs between 0.4 grams and 2.0 grams. The weight can vary depending on the species of hummingbird, but it remains relatively consistent across the board.

To put that into perspective, think about everyday items you might be familiar with:

  • A standard paperclip: 1.0 gram
  • A grain of rice: 0.02 gram

Hummingbird eggs are light and fragile. Even the heaviest hummingbird egg is lighter than a paperclip. That’s fascinating!

Another point to consider is the size of the egg. Hummingbird eggs are usually between the size of a coffee bean and a jellybean, measuring about 1 to 1.5 centimeters in length.

As you can see, hummingbird eggs are tiny and lightweight. But, despite their size, they are still capable of holding the life of a baby hummingbird that will soon amaze us with its breathtaking speed and agility.

How Much Does a Ruby-Throated Hummingbird Weigh?

You might be surprised that the tiny ruby-throated hummingbird is incredibly lightweight. In fact, an adult ruby-throated hummingbird typically weighs between 2.1 and 6.3 grams. To put this into perspective, consider the following everyday items for comparison:

  • A U.S. penny weighs 2.5 grams

Sexual dimorphism plays a role in the weight of these fascinating little creatures. Male ruby-throated hummingbirds are generally smaller and lighter than their female counterparts. A male weighs around 3.4 grams, while a female weighs about 3.8 grams.

Another fascinating aspect of the ruby-throated hummingbird’s weight is that it can fluctuate throughout the day. Due to their high metabolic rate, which requires them to consume a substantial amount of nectar, their weight can change by up to 15% within a single day. This impressive energy consumption is necessary to sustain their rapid wingbeat rate, which averages around 53 beats per second.

In conclusion, the ruby-throated hummingbird is a remarkably lightweight bird, weighing only slightly more than a penny. With such a small body and high energy demands, it’s no wonder that these little marvels of nature capture our fascination and admiration.
