The other day I was rewatching the "Signals and Song" episode of The Life of Birds and took special interest in the section about avian eyesight. David Attenborough, ye giver of knowledge, explained that many birds possess color vision far superior to our own, often allowing birds to see light in the UV spectrum. The ability to see UV light means that in some cases - examples in the program include Budgerigar and European Starlings - birds appear to each other much different than they appear to us.
