5 Surprising Facts You Probably Didn't Know About Hummingbirds

Hummingbirds can flap their wings up to 100 times per second, making them incredibly fast and agile in flight.

The smallest known bird in the world is a bee hummingbird which is just 5.5 cm in length. With some species growing to a length of only 4 inches, hummingbirds are among the smallest birds.

Hummingbirds are the only birds who can fly backwards. This is due to their unique ball-and-socket wing joints, allowing for incredible aerial mobility.

They can quickly consume nectar with their long, forked tongues that reach far beyond their beaks.

A hummingbird's brain makes up 4.2% of its body weight, the biggest percentage of any bird. This helps them remember where flowers are and where to feed.
