Here is the list of top 10 smallest birds in the world:

1. World’s Smallest Bird: Bee Hummingbird

Length: 5.5 cm

Scientific Name: Mellisuga Helenae

The world’s tiniest bird, the bee hummingbird, measures a mere 5.5 cm (for males; females are slightly larger at around 6.1 cm). These delicate creatures, weighing only 1.95 grams, can be found exclusively in Cuba. They sip nectar from flowers and often mistaken for buzzing bees, hence their name.

The Esmeraldas Woodstar, a rare neotropical hummingbird, belongs to a group of six smaller species. They are among the tiniest birds, with males sporting a vibrant purple throat. These birds inhabit the Pacific coast of western Ecuador, thriving in forests and feeding on nectar. Sadly, deforestation poses a significant threat to them, making them a vulnerable species in need of habitat protector.

3. World’s Third Smallest Bird: Calliope Hummingbird

The Calliope hummingbird, the tiniest native bird in the US and Canada, dwells in the western region from California to British Columbia. During winters, it migrates to the Southwestern US, Mexico and Central America. Once believed to be in the Stellula genus, recent evidence suggests it belongs to Selasphorus. Its name, Calliope, comes from the Greek muse and its previous genus name means “little star.”
