I think birds of prey see in colour, but I haven’t checked.

Pretty bird and a great photo. From what I’ve been able to find, cats have some colour vision, but not nearly as acute as humans. In the eye there are two types of structures. Rods are receptors for light and cones are receptors for colour. Cats have more rods than us which is why they see in low light. They have about ten times less cones, though, so their colour vision is limited. It’s thought they see about the same as a colour blind human. Better with blues, greys, greens and yellows not so good with pinks and reds and purples. Apparently they’re also nearsighted.
That’s a well camouflaged dinosaur.
Lady chaffinch. Though I don’t know, do cats and birds of prey see colour?

All birds see in colour, and they are tetrachromants, so they see even more colours than primates do.
Thinking about it, it wouldn’t make sense for them to be so bright if they couldn’t see it. Nature rarely wastes resources.
Love the ruffled feathers in the head, looks as if she’s curious about something.
