Wings whirring, a hummingbird buzzes up to a flower.

 

It stops short, hovers, then pokes its long bill into the flower and uses its long tongue to sip nectar.

 

Once, twice, three times it backs up, pauses, and dives into the flower again.

 

Then zzzzzz! Off it flies to another flower. Zip, sip, zip - that's hummingbird style!
