Are Hummingbirds The Smallest Birds In The World

Last Updated on October 19, 2023 by Susan Levitt

When it comes to birds, size can vary greatly. Some birds are so large that they cannot even fly, while others are incredibly small and nimble. One question that often arises is whether or not hummingbirds are the smallest birds in the world. As an AI language model, we do not have a personal opinion on this matter, but we can certainly provide you with some objective facts.

Firstly, it is important to define what we mean by "size." In terms of birds, size can refer to a variety of measurements such as body length, wingspan, weight and more. For the purpose of this article however, we will be focusing primarily on body length as it is often used as a standard measurement for bird size comparisons. With that said, let’s dive into the world of hummingbirds and other small bird species to determine if hummingbirds really are the smallest birds in existence.

Introduction to the Question

You’re here to find out if there’s a species of bird that could fit in the palm of your hand. The answer is yes, and it’s none other than the hummingbird. These tiny birds are known for their ability to hover in mid-air by flapping their wings at incredible speeds. With over 300 species of hummingbirds, they can be found throughout the Americas, from Alaska to Tierra del Fuego.

While there are other small birds in the world, such as the bee hummingbird and fairyfly, the hummingbird remains the smallest bird family on Earth. The bee hummingbird is only found in Cuba and measures up to 6 cm long with a wingspan of around 7 cm. Meanwhile, the fairyfly is a type of parasitic wasp that ranges from 0.14mm to 1mm long – making it smaller than some single-celled organisms.

Hummingbirds have unique adaptations that allow them to survive despite their size. For example, they have one of the highest metabolic rates among all animals, which means they need to consume large amounts of nectar each day just to sustain themselves. Their hearts also beat incredibly fast – up to 1,260 beats per minute – which helps pump blood through their bodies efficiently.

In conclusion, while there are other small birds and insects in existence, none quite compare to the humble hummingbird when it comes down to being considered as "the smallest." It is fascinating how these tiny creatures can survive thanks to their unique adaptations and specialized diets. We should continue learning about these amazing creatures so we can understand how we can better protect them for future generations.

Definition of Size

The section currently focuses on defining the size of avian species. When we talk about bird size, we are usually referring to two main measurements: weight and length. While there are over 10,000 species of birds in the world, their sizes can vary greatly. For example, the largest bird in terms of weight is the ostrich, which can weigh up to 320 pounds. At the other end of the spectrum, there are tiny birds like hummingbirds that weigh only a few grams.

When it comes to defining bird size based on length, things get a bit more complicated. This is because some species have longer tails or wings than others, even if their body length is similar. Therefore, scientists often use standardized measurements such as wing chord (the distance between the wrist and tip of the longest primary feather) or culmen length (the measurement from the base to the tip of a bird’s beak) to compare different birds’ sizes.

So where do hummingbirds fit into all this? Well, they are certainly small by both measures. In terms of weight, most hummingbird species weigh less than an ounce (which is approximately 28 grams). And while their body lengths vary depending on species and gender – ranging from just over two inches to around five inches – they have relatively short wings and tail feathers compared with other birds.

While hummingbirds might seem incredibly small to us humans, they are not actually the smallest avian species in existence. That title belongs to bee hummingbirds – found only in Cuba – which measure just two and a quarter inches long and weigh less than two grams! However, despite not being absolutely smallest bird in existence these little creatures continue to captivate many with their incredible speed and agility as well as their vibrant colors making them truly spectacular creatures!


You’ll be absolutely amazed by the incredible size and agility of these tiny creatures found in Cuba. Hummingbirds are indeed one of the smallest birds in the world, with some species measuring only two inches long and weighing less than a penny. Despite their small size, they have exceptional flying abilities and can flap their wings up to 80 times per second. Their high metabolism allows them to consume nectar from flowers that are twice their body weight in a single day.

Hummingbirds have unique adaptations that enable them to fly so quickly and efficiently. Their wings are almost completely feathered, allowing for greater flexibility and control during flight. They also have extremely strong pectoral muscles that provide the power needed for hovering and darting movements. Additionally, they have specialized tongues that can extend twice the length of their bills to reach deep into flowers for nectar.

While hummingbirds may be small, they play an important role in pollinating plants throughout their habitats. As they feed on nectar from flowers, pollen sticks to their feathers and is carried from plant to plant as they move about. This helps ensure the survival of various plant species within ecosystems where hummingbirds reside.

In conclusion, hummingbirds are incredibly fascinating creatures due to their small size and impressive flight capabilities. They serve an important ecological function as pollinators while also being visually stunning with vibrant feathers and unique markings. It’s no wonder why so many people find joy in observing these tiny birds fluttering around gardens or buzzing past on hiking trails.

Other Small Bird Species

We’re going to talk about some other small bird species that are just as fascinating as hummingbirds. First up is the Bee Hummingbird, which holds the title of being the smallest bird in the world. The Elf Owl is another tiny bird, measuring only around 5 inches tall and weighing less than an ounce. The Weebill and Goldcrest are also noteworthy for their diminutive size, both measuring around 3-4 inches in length.

Bee Hummingbird

Well, would you look at that – this little guy is almost too small to see! We’re talking about the bee hummingbird, which is not only the smallest hummingbird species but also the smallest bird in the world. These tiny birds are found exclusively in Cuba and can weigh as little as 2.6 grams and measure just 5-6 centimeters long.

Here are three fascinating facts about weebills:

  1. They have curved bills that allow them to extract insects from bark crevices.
  2. Weebills build intricate nests made of spiderwebs and grass on the tips of branches.
  3. They have a unique call that sounds like "wee-bill" – hence their name!


You’re going to love meeting the Goldcrest, a teeny-tiny bird with a big personality that’s sure to charm you with its energetic movements and cheerful calls. Found in Europe and Asia, this tiny bird is just 3.5 inches long and weighs only 0.2 ounces, making it one of the smallest birds in the world.

Despite its size, the Goldcrest is a master of survival. It has adapted well to cold climates by increasing its metabolic rate during winter months and fluffing up its feathers for insulation. It feeds on insects and spiders found in coniferous forests, often hanging upside down from branches to catch them. The Goldcrest’s song is high-pitched and melodious, resembling that of a whistle or flute. Its energy levels are impressive as it hops agilely from branch to branch in search of food or mates. Overall, the dainty little Goldcrest is a fascinating creature worth admiring for its resilience and tenacity in a world full of giants!

Comparing the Sizes

As you compare sizes, it becomes clear which feathered friend reigns supreme in the realm of tininess. While the Goldcrest is indeed a small bird, its size pales in comparison to that of the hummingbird. The smallest species of hummingbirds can measure only 2.25 inches in length and weigh less than a penny! In fact, some species are so tiny that they are often mistaken for insects.

One factor that contributes to the hummingbird’s petite size is their high metabolism. These birds have to consume a large amount of nectar each day to fuel their energy demands, which means they need to be light enough to fly efficiently. Additionally, their wings beat at an incredibly fast rate – up to 80 beats per second – allowing them to hover and maneuver with incredible speed.

Despite their small stature, hummingbirds are known for their impressive feats of strength and endurance. They migrate thousands of miles each year between North and South America, crossing open ocean and enduring harsh conditions along the way. They also have one of the highest body temperatures among birds, which helps them maintain their fast metabolic rate.

In conclusion (oops!), while there are certainly other small birds out there like the Goldcrest, none quite compare in terms of sheer tininess as the mighty hummingbird. These little dynamos may be small in size but they more than make up for it with their remarkable abilities and resilience in the face of adversity.
