How does a hummingbird’s vision differ from a human’s?
A It can’t see bright colors
B It can’t see until it’s a year old
C It can see ultraviolet light
Hummingbirds rely on excellent vision to fly and find food, and their sensitivity to ultraviolet light allows them to see some colors that humans can’t. We humans have three types of color receptors in our retinas, called cones, that allow us to see blue, green, and red light, respectively. Hummingbird eyes have been shown to have four types of cones—the fourth allows them to see distinct colors by blending UV light with the other lights to create entirely new ones.
The correct answer is It can see ultraviolet light.
