Are Hummingbirds Colorblind?

Scientists have long known that some animals, especially birds, have better eyesight than humans. As is the case with most primates, humans are trichromatic.

Are Hummingbirds Colorblind?

This means that the human eye has three types of color-sensitive receptors or cones: blue, green, and red.

Are Hummingbirds Colorblind?

The birds on the other hand have four colored cones, which means they are tetrachromatic.

Are Hummingbirds Colorblind?

Furthermore, the human eye can see rainbow colors – red, orange, yellow, green, blue, indigo, and purple.

How Did The Scientists Find Out The Answer?

Mary Stoddard, a Princeton University evolutionary biologist, and her team had conducted a series of field experiments with wild broad-tailed hummingbirds.

How Did The Scientists Find Out The Answer?

Scientists had set up several bird feeders outfitted with LED devices near the laboratory.

The Vividly Colored World of Hummingbirds

As already mentioned, their vision, especially the ability to spot different color spectra, helps them to choose food.

Are Hummingbirds Colorblind?

The researchers concluded that hummingbirds have the ability to distinguish a variety of no spectral colors, including UV + red, UV + green, purple, and UV + yellow.
