Yesterday’s nasturtium looked inviting to a hummingbird, but how does he drink its nectar?
This Science Friday video — originally published on May 27, 2011 — shows how both the dog and the hummingbird use their tongues to drink.
The dog drinks by sucking liquid up in a column, not by using its tongue as a ladle to its mouth.
The hummingbird is even more amazing. Its tongue has a zipper that opens in liquid and shuts when withdrawn. It holds the liquid inside its tongue.
Watch and see!

p.s. What kind of hummingbird is this? (I have no idea.)
