10 of the World’s Smallest Birds

Australia may have a reputation for ecosystems occupied by large and deadly animals, but the petite weebill is proof that this continent is far more diverse than that. Its name is derived from its small size, but it also has a cry that sounds as if it’s saying “I’m a weebill”. These cries are loud and can be heard all year long in environments where this species can be found.

And while these birds may be restricted to the continent, they’re dispersed widely over the landmass, appearing practically everywhere except in particularly harsh sections of the interior. These birds display distinctive plumage that’s a combination of cream and a bright yellow, and they tend to make a home and stay there for the rest of their lives. Highly sociable birds, they’ll hunt in flocks — often including other bird species — and mating pairs will raise their young together.
