Top 10 Smallest Birds in the World

The smallest birds in the world captivate our attention and remind us of the incredible diversity found in nature. From the vibrant colors of the bee hummingbird to the resilience of the weebill and the remarkable migratory journeys of the goldcrest, these tiny creatures leave a lasting impression. They serve as a testament to nature’s ability to create wonders in even the most compact forms.

While these birds may be small in size, they showcase remarkable adaptations and behaviors. Their diminutive stature allows them to access nectar from delicate flowers, contributing to pollination and ecosystem health. Despite their small size, they exhibit resilience, agility, and remarkable migratory capabilities.


1. Bee Hummingbird (Mellisuga helenae)

The bee hummingbird, scientifically known as Mellisuga helenae, holds the remarkable distinction of being the smallest bird in the world. Measuring a mere 2.25 inches in length and weighing a mere 0.07 ounces, these tiny creatures are a true marvel of nature.

While most hummingbirds possess slender bodies, the bee hummingbird stands out with its plump physique and distinct appearance. Despite its small size, it exhibits unique features that set it apart from other hummingbird species.

Distinguishing between male and female bee hummingbirds is relatively easy due to their noticeable differences. The males boast vibrant and bright colors, with bluish upper parts, while the females exhibit less flamboyant hues, often appearing greenish in coloration.

Due to their diminutive size, bee hummingbirds do not lay a large number of eggs. Females typically lay only two eggs, which are approximately the size of coffee beans. This limited reproductive capacity further emphasizes the delicate nature of these remarkable birds.

In terms of mating behavior, bee hummingbirds differ from birds that form lifelong monogamous pairs. Instead, they exhibit polygamous tendencies, engaging in multiple partnerships throughout their lives. These astonishing creatures primarily inhabit the island of Cuba and nearby regions in the Caribbean. Their small size allows them to access nectar from delicate flowers, making them important pollinators in their ecosystems.

The bee hummingbird serves as a captivating reminder of the incredible diversity and adaptability found within the avian world. Despite their miniature stature, these birds exhibit remarkable resilience and continue to fascinate scientists and nature enthusiasts alike.

2. Esmeraldas Woodstar (Chaetocercus berlepschi)

The Esmeraldas woodstar, scientifically known as Chaetocercus berlepschi, is a small neotropical species of bird belonging to the hummingbird family. These charming birds hold the distinction of being the smallest birds in South America.

Measuring only about 2.5 inches in length and weighing nearly 0.8 ounces, the Esmeraldas woodstar showcases remarkable adaptability despite its diminutive size. Although the woodstar family consists of six subspecies, their distinctions and characteristics are not extensively studied, leaving much to be discovered about these fascinating birds.

The Esmeraldas woodstar primarily inhabits semi-deciduous or evergreen forests in Ecuador, a country located in South America. Within these lush environments, they thrive by feeding on nectar from flowering shrubs and trees. Their small size and specialized feeding adaptations, such as their long bills and tongues, allow them to extract nectar with precision and efficiency.

Sexual dimorphism is prominent in the Esmeraldas woodstar, with males and females exhibiting distinct differences in appearance. One key distinguishing feature is the vibrant purple throat displayed by the males. This striking coloration serves as a visual cue for both attracting mates and establishing dominance within their territories.

Despite being poorly studied, the Esmeraldas woodstar holds an important ecological role as pollinators. As they feed on nectar and move from flower to flower, they facilitate the transfer of pollen, contributing to the reproductive success of various plant species in their habitat.

The Weebill, scientifically known as Smicrornis brevirostris, holds the title of the smallest bird species in Australia. Measuring only up to 3.5 inches in length, these tiny birds are found throughout mainland Australia, particularly in dry eucalyptus forests and mallee habitats.

Despite their small size, Weebills play an important ecological role. They contribute to maintaining the health of trees by feeding on a variety of insects that can harm the trees. By controlling insect populations, Weebills indirectly benefit the overall ecosystem of their habitats.

Unlike some bird species, Weebills do not have a fixed breeding season. Instead, their breeding patterns are influenced by climatic conditions. These birds have the ability to breed at any time of the year, but they most commonly engage in breeding activities from July to May.

During the breeding season, Weebills construct small, cup-shaped nests made of plant materials such as grass, bark, and spiderwebs. These nests are typically located in the forks of tree branches or amongst foliage. Female Weebills lay a clutch of eggs, and both parents share the responsibility of incubating the eggs and caring for the hatchlings.

Weebills have distinctive plumage, characterized by shades of olive-green on their upperparts and a paler yellowish color on their underparts. Their small, compact bodies and short beaks are well-adapted for maneuvering through dense foliage in search of insects and foraging for small seeds.

8. Costa’s Hummingbird (Calypte costae)

Costa’s hummingbird, scientifically known as Calypte costae, is another fascinating member of the hummingbird family. These tiny birds weigh no more than 0.11 ounces, making them incredibly lightweight. They typically reach a maximum length of 3 to 3.5 inches, with a wingspan measuring around 4.3 inches.

Costa’s hummingbirds predominantly inhabit deserts, semi-deserts, and open meadows in North America. These arid regions serve as their natural habitats, where they find suitable resources and nesting sites. However, if the living conditions in their native environment become harsh or resources become scarce, Costa’s hummingbirds may undertake migrations to other countries in search of better conditions.

Reaching sexual maturity at around one year of age, Costa’s hummingbirds engage in breeding activities between January and May each year. Unlike some other bird species, they do not form exclusive pairs. Instead, both male and female Costas engage in multiple mating interactions during the breeding season.

The vibrant plumage of the male Costa’s hummingbird is a sight to behold. With stunning purple-blue feathers adorning their head and throat, they exhibit a striking and iridescent appearance. These beautiful colors play a crucial role in attracting mates and establishing dominance during territorial displays.

Costa’s hummingbirds, like their larger counterparts, feed primarily on nectar from flowering plants. Their long, slender bills are perfectly adapted for extracting nectar from flowers, and they play a vital role in pollination as they move from one blossom to another.
