THE AMAZING HUMMINGBIRD

The hummingbird is the only bird species that can fly backward. It’s also the smallest bird – the bee hummingbird from Cuba grows to only about 5cm.

Hummingbirds are also the invertebrates who use the most energy. One study found if a hummingbird were the size of a human, it would need to consume a can of cold drink for every minute it hovers in the air because of how fast it metabolises sugar.
