FLIGHT: The Genius of Birds (Pt.4) - Hummingbird Tongue

If birds are randomly evolved creatures, then why are Aerospace Engineers copying them today?

In this short clip, we see yet more of the amazing design and engineering of birds' bodies and mechanisms. In order to fuel its heart and wings that can flap up to 100 times-per-second, a hummingbird must eat several times an hour. This groundbreaking sequence from FLIGHT: THE GENIUS OF BIRDS illustrates the system of mechanisms that enable a hummer to consume several times it body weight in nectar each day.
