well shiat. Now I need to look at all my bird feathers under a UV lamp.

Awesome!

I'm almost 40 so I will start being in to birds around there. Still, quite neat.

So do birds see all of the stains in hotel rooms?

So that cocky pigeon strut is completely justified. Those pigeons be pimpin'!

Yes. And that's why they shiat on your car.

I think it's cool that it's a meme to throw UV on basically every animal we can get close to now just to see what happens.

We should make that the next TikTok challenge.  I am dying to see some Poindexter try it with a møøse.

No, subby. If we could see UV like birds do, that "UV flashlight" would just be a bright light in a different color.

Those colors on the wings are fluorescence, where the UV light causes the emission of visible light, which the perfectly normal camera sees just like our eyes see it.

Furthermore, that's fluorescent ink that was used to mark the bird, not a natural color on the feathers.

Here's a better attempt to show how birds see differently from humans, although I'm a bit skeptical about the bird's-eye renderings.

Here's one I like a little better, where they show foliage shot in RGB vs. VGB.

Got my eye lenses swapped out because of cataracts. I can now see at least some UV. Nothing really unusual, except that looking at a UV flashlight is like looking at an arc welder.

Maybe that's why none of those fake bird of prey statues they use to keep pigeons off buildings work. We need to paint them with the same UV colours birds see not just the visible light spectrum we see.
