I've always wondered: why don't chickens look down when they scratch?

Quote: "As birds can see ultraviolet light, that means that when a bird looks at another bird, they don't see what we see.

In fact, a study of 312 bird species in 142 families showed that all bird families have ultraviolet feathers. Even more interestingly, male and female birds that look the same to us look very different under ultraviolet light - so birds can often tell another bird's gender when we can't."

And here's the paper that studied ultraviolet plumage:

The ubiquity of avian ultraviolet plumage reflectance
