15 Smallest Birds in the World

Birds are among our favorite animals because of the fantastic contradictions within this class: fragile and strong, fastest animals and flightless birds, unicolor and colorful birds, cute and weird birds. The list goes on.

For this reason, we’re presenting you today with the smallest birds in the world! While most of the tiniest birds are hummingbirds, we also feature some small passerine birds.

Without further ado, let’s talk about these tiny birds!

1. Bee Hummingbird – The Smallest Birds in the World

The Bee Hummingbird is the smallest bird in the world
Bee hummingbirds (Mellisuga helenae) are the smallest birds in the world and measure only 2.25 inches long. Weighing only 0.07 ounces, these little birds are the tiniest species of hummingbird.

Typically, hummingbirds have slender bodies, but bee hummingbirds are plump and look slightly different from the other hummingbird species.

It is easy to distinguish between male and female bee hummingbirds, as the males are brighter and have bluish upper parts, while the females are less colorful and greenish.

Because these are the tiniest birds in the world, you can imagine they don’t lay many eggs. Females lay two eggs which are as big as coffee beans.

Unlike other birds that mate for life, these petite birds are polygamous and have multiple partners throughout their life.

On a typical flight, their wings can beat 80 times per second. However, that increases to 200 beats per second when they engage in a courtship flight.[1]
