Hummingbird Anatomy: Why These Tiny Fliers Are Amazing
Updated: Feb. 24, 2023There's much more to hummingbird anatomy than you know. Discover the fascinating physical traits that make hummingbirds tick.
All About Hummingbird Anatomy
No fliers are as well-equipped to drink nectar as hummingbirds. With long, thin bills and tongues that lick up to 13 times a second, their mouths alone make them extraordinary. But the wonder doesn’t stop there—they are among the few birds with the ability to hover and even fly backward, allowing them to easily zip from flower to flower. Learn more about why hummingbird anatomy is so incredible.
What makes hummingbird feathers so shimmery?
Eyes
These birds have a keen sense of sight. Their large eyes pick up as many colors as human eyes do, plus ultraviolet light.

Wings
Lead edges of hummingbird wings create tornado-like vortexes to help with hovering. The smaller the hummingbird, the faster its wings beat. But it’s not the speed of its wings that allows a hummingbird to hover—it’s the structure of its wing joints. Hummingbirds can rotate their wings as they flap. This lifts them into the air on both the forward and backward strokes.
Did you know—the hummingbird heart rate is unbelievably fast!
Tongues
Hummingbird tongues act as thin pumps that contract to draw in nectar from flowers and sugar water from feeders.

Feet
Their weak, dainty feet are used for perching only; hummingbirds don’t walk or hop. Learn more about how bird feet work.
Body Temperature
An Anna’s hummingbird‘s body temperature is typically 107 degrees, but it can drop down to 48 degrees when it goes into torpor, a kind of deep sleep, during cold weather.
Tails
Sturdy tail feathers are used like rudders to make hairpin turns. Additionally, research shows that the male Anna’s stiff tail feathers make songlike sounds during courtship displays.
