I love the idea that birds have evolved ultraviolet sexual ornaments that humans can't even see. Just as humans have evolved ideological sexual ornaments that birds could never understand.https://twitter.com/scifri/status/1161001898251624449 …

Birds don’t just see the world from higher up than the rest of us; they also see a whole range of light that we can’t. Birds have a fourth color cone in their eyes that lets them see ultraviolet wavelengths. http://scifri.me/t52 pic.twitter.com/S3sJq6OnlF

  A whole new rainbow of colors. Makes me wonder how beautiful the world would be if we could see it from these many different perspectives.

  You are correct. As a nightjar, I have never understood the human’s ideological regalia.

  The supposedly drab males aren't drab at all.

  A little jealous that I can't experience seeing the world in this colourful way.

  Good reason for genetic manipulation. I want those cones. I want more colours.

  Once read a book filled with animal examples of mating rituals to argue that human males should regularly bring trivial gifts to their females to reinforce the pairing, and that failure to do so invites competitors. Many bird examples, even pair-bonding birds exhibit that trait.

  Aren't there a few human tetrachromats though? Maybe they could see these bird sexts?
