Photos: Hummingbirds Slurp Up Tasty Nectar

Hummingbirds zip from flower to flower, licking up nectar with their tongues. The exact way these tongues work has long eluded scientists, but a new study shows that hummingbird tongues are elastic micropumps that rapidly pull in nectar once they reach the inside of the flower.

Sparkling violetear

Hummingbirds fuel their high-speed lifestyle with tiny drops of nectar and the occasional fly. (Image credit: Kristiina Hurme)

Black-throated mango

Pretty plumage

Hummingbirds feed on long, tubular flowers that make nectar hard to reach. (Image credit: Kristiina Hurme)

Split second

Nectar snack

When hummingbirds drink, they are licking 15 to 20 times per second. The amazing speed at which hummingbirds can drink is possible due to the physics of the elastic micropump, the researchers said.
