Aug. 29 (UPI) --According to a new study, some birds of prey can detect contrasts between objects at a greater distance than humans -- but only if the object is a different color than the background.

If optimists see the world through rose-colored lenses, some birds see it through ultraviolet ones. Avians have evolved ultraviolet vision quite a few times in history, a new study finds. Birds depend ...

Birds can see ultraviolet wavelengths, giving them a fuller view of the world. Comparing our vision with that of birds, well, at least we can claim opposable thumbs. Birds see a vastly different world ...

BERLIN (AP) — Scientists say they have sequenced the genome of the brown kiwi for the first time, revealing that the shy, flightless bird likely lost its ability to see colors after it became ...

In this episode of The Highlights, we're joined by Mary Caswell (Cassie) Stoddard, a professor in the Department of Ecology and Evolutionary Biology (EEB). We discuss her career in sensory ecology and ...

A gene for red colour vision that originated in the reptile lineage around 250 million years ago has resulted in the bright red bird feathers and 'painted' turtles we see today, and may be evidence ...

Researchers have spent three years studying hummingbirds to deduce whether they can distinguish between spectral and nonspectral colors. A newly published paper has confirmed that these incredible ...

Wild turkeys have incredible eyesight. Their ability to sense a predator, like a hunter leaning back against a tree, is uncanny. Turkey vision can seem even supernatural at times. But really, it’s ...
