    TIL crows, starlings and similar birds only *look* black to us — they’re actually very colorful in ways human eyes are unable to perceive. 🤯

    Remember that next time people can’t see your “colors”.

    Some colors just require different eyes.

      @leaverou That's a starling, not a crow, but very cool nonetheless! Magpies also have pretty iridescent green-black feathers, while crows and ravens seem inky black - would love to see a bird's eye version of a raven.

              @catraxx Thanks! I did fact check it and it seems to apply to crows too, but couldn't tell what the bird was in the infographic. I edited the OP.

                      @leaverou Could you make the colors visible by taking a photo in RAW format and adjusting the color settings? I don't know how camera sensors work, but maybe they're able to capture these colors.

                        @leaverou I don't think that infography makes any sense. We do have a sensibility to green, but we still see colors from 400nm to 800nm. Also, what species of crow is that? I don't know any with white spots and a yellow beak.

                        Is there any source for that?

                        Edit: definitely, the curves don't mean anything

                          @ShnoofleBear @leaverou it's arbitrary really - you can use freq or wave length for scale

                            @petitmote @leaverou having less types of cone cells means you have more metameres, but I don't think it applies here. chroma range is another matter. and there's brightness range.

                              In the right sunlight you can see most of these colors (Never seen one this vibrant).
                              But I'd imagine a camera has the range to pick a lot of it up since the visible spectrum is the typical target.

                                @mattesilver @leaverou yes, I don't think the curve corresponds to the sensibility of the numan eyes nor the colors of the photography

                                        I used to toss peanuts to crows regularly, and they were comfortable approaching me. One day in early winter, an hour or so after sunrise, a crow walked close, in front of me, between me and the sun. I was wearing amber polarized sunglasses, and just for ten seconds or so I saw red and turquoise bars on its wings - one of the most astonishing and beautiful things I remember. I've never been able to duplicate it, and have never found corroborating evidence, but I remember thinking "oh that's how they can tell each other apart"

                                          TIL crows, starlings and similar birds only *look* black to us — they’re actually very colorful in ways human eyes are unable to perceive. 🤯

                                          @leaverou Evidence, if needed, that we do not see the real world - what we experience is an approximate proxy.

                                          Besides - the light rays from an object tend to fan in all directions - we only got a tiny sliver of these rays impinging on our retinas. So we only ever perceive very partially. And only perceive a minuscule fraction of all wavelengths.
