HD Ready? Humans vs. Animals

People often assume animals like cats have highly-tuned senses far beyond our own, with their ability to see in the dark, assuming that humans trump the abilities of animals only in brain power.

But a recent study revealed that many animals are viewing in low resolution where humans are seeing in crystal clear HD, with only a handful of bird species operating at even greater levels of definition.

Human eyes aren’t particularly adept at distinguishing colors or seeing in dim light, but the latest research shows that across the animal kingdom, most species “see the world with much less detail than we do,” said Eleanor Caves, first author of the research paper published on May 30.

“A few birds of prey do better,” said a statement from researchers at Duke University. “For instance, the wedge-tailed eagle of Australia can see 140 cycles per degree, more than twice the limit of human visual acuity. Eagles can spot something as small as a rabbit while flying thousands of feet above the ground.”

But with the exception of these birds of prey—some eagles, vultures and falcons—most birds see less than half as much detail as humans, said the researchers.
