10 Smallest Birds In The World

Bee Hummingbird (5.5cm)

The bee hummingbird measures just 5.5 cm (males) and 6.1 cm (females) long, weighing 1.95 grams. These tiny birds are found only in Cuba and feed on flower nectar.

Esmeraldas Woodstar (6.4cm)

The Esmeraldas woodstar, a slightly larger hummingbird, inhabits only the west coast of Ecuador. This rare bird has an estimated population of 1,000 to 2,700 mature individuals, which is declining due to habitat loss.

Calliope Hummingbird (7cm)

The calliope hummingbird, the smallest bird native to the U.S. and Canada, measures 7 cm long. It feeds on nectar and small insects. Named after the Greek muse Calliope, its call is a high-pitched zing.

Costa’s Hummingbird (7.6 cm)

This striking male with a bright purple cap and throat resembling a plum dazzles females during courtship displays by catching the sunlight. These birds are found in the southwestern United States and Mexico.

Pale-Billed Flowerpecker (8 cm)

The pale-billed flowerpecker has a symbiotic relationship with the mistletoe Dendrophthoe falcata, feeding on its berries, pollinating the plant, and aiding in seed dispersal.

Weebill (8cm)

The aptly named weebill, Australia’s smallest bird, is a grey-and-yellow insectivore with a stubby beak. Weighing just 6 grams, similar to a pencil, it primarily feeds on beetles and flies and occasionally eats seeds.

Cape Penduline Tit (8cm)

In southern Africa, the petite passerine builds nests that have a clever design: a false entrance leading to an empty chamber to baffle egg thieves and a smaller real entrance that shuts after the bird enters or leaves.

Goldcrest (9cm)

The UK’s smallest bird, the goldcrest, is known as the "king of the birds" in European folklore. It sports bright orange/yellow plumage on its crown. Weighing less than a postcard, females can lay up to 12 eggs, about one and a half times their body weight.

Common Firecrest (9.3cm)

The Firecrest features a yellow crown, black eyestripe, and white eyebrow stripe. Found in the UK, Europe, and parts of northwestern Africa, it is admired for its striking appearance.

Spotted Pardalote (9.5 cm)

Australia's smallest bird after the Weebill, the colourful Spotted Pardalote, is also known as the "headache bird" for its relentless repetitive call during breeding season.
