Hummingbirds Don't Suck Nectar In - They Drink It!

For over two centuries, scientists have maintained that hummingbirds suck in nectar by capillary action (the same way liquid gets sucked up by a straw), using the tube-like channels that lie inside their tongues. However, a new study done by Alejendro Rico-Guevara, an ornithologist from the University of Connecticut, refutes that, and he has video footage to prove it.
