Hummingbirds are tiny creatures that live in tropical regions around the globe. They have long tongues that they use to feed on nectar from flowers. How do these birds manage to get such large amounts of liquid into their mouths?

Hummingbirds have a unique feeding mechanism called the ‘pumping action’. This allows them to extract water from the nectar and then transport it back to their throats. In order to do this, the bird has to flap its wings rapidly, creating a vacuum effect.
