Color Vision in Birds

Similar to Sam's post about ultraviolet sensitive vision in aye-ayes, I found an article tracing the genetic roots of ultraviolet sensitive vision in birds. Posted just a few days ago, a study conducted on 40 bird species reveals that ultraviolet vision in birds evolved due to single nucleotide changes. In birds, there are two amino acid alterations that can change color vision in birds, and one particular SNP occurred at least 11 different times!
