I did research bc I was thinking about bird eyes drying up in the wind and it turns out that they have eyelids under their other eyelids called ✨ nictitating membranes✨ and they’re ✨mostly transparent✨
Which is actually pretty cool. It makes sense because biology usually does (emphasis on usually)
Here is a picture of said nictitating membrane (warning: horrendous)
:D
And basically nicky membranes do the job of eyelids but while being transparent because birds can’t afford to be blind for 0.2 seconds that’s just too damn long. They also have proper eyelids but nicky membranes for the win I do suppose.
Also nictitating straight up just means ‘blinking’. It’s called a blinking membrane. But you know scientists, they want to feel smart with their fancy words that keyboards say aren’t real.
>:(((
But basically yeah birds have secondary (Google says tertiary but I don’t care) eyelids.
Afterthought: Every time I see nictitating membrane I’m reading it as nicotine membrane.
I am assuming this is maybe from some ask meme but I cannot find it so I will instead reward this message with a random animal fact.
Did you know pigeons produce "milk" from their crop? When their babies are very young they can't handle regurgitated food, so they'll secrete this goo for their babies and feed them that for a little while until they can deal with being thrown up in like a proper bird.
Every year I decide to draw biblically accurate Turkeys, and every year I am reminded that Turkeys are wack ass birds.
This is a SPECIMEN of a turkey and it still looks wacky as hell. Why are they so large? Why are their heads so small? The little tuft of chest hair? The droopy beak? Why is he built like that?
Screw the bald eagle, Benjamin Franklin was right this thing should’ve been our national bird.
Once upon a time (10 minutes ago) I wrote about nictitating membranes on birds. Now I’m putting on my writer’s cap (one of those multicoloured hats with the propeller on the top) and bringing out my world building tools (an inflated toy hammer and ibuprofen).
Avians. Angels. Archangels. I don’t care what you call them, I’m talking about Bird Boys. Flapper Folk. Feathered Fuckers. Them Man with Burd Wings. Squawkers in the form of Homo sapiens (alternatively, Homo erectus).
I’m SAYING that more-human-than-bird birdfolk may also have a need for nictitating membranes (every time I write that damn word, someone somewhere dies from the absurdity) because, well, they’re flying. And, thus, unless they be blinking a lot (every bird ever: 😧) then they’d be needing nicky membranes.
Eyelids: poo, make you blind for 0.2 seconds, not transparent, cannot see through, thick, ugly, poo poo, terrible 👎🤬😰😫🙄🥱🤮
Nicky membranes: transparent, can see through, visibility 100% throughout blinking process, thin, lovely, sleek, elegant ✨🥰😍❤️❤️🔥😚😩🤯
But for real though, human eyes are definitely not equipped to deal with the brutal, destructive force of wind. Eyes v Wind, I wonder who will come out victorious with a devastating 100-0.
Humans used to have nicky membranes themselves, but we lost them because we weren’t smart enough to realise their amazing worth (nicky please come back I miss you we can talk about it nicky ple-)
OKAY SERIOUSLY THOUGH (watch me not be serious like the clown I am) nictitating membranes do the exact same job as normal eyelids, which is blink. Blinking clears away whatever is in the eyes that isn’t supposed to be there (e.g, prophetic visions of me with your mom) and ~moisturises~ the eye. While maintaining vision (quoth the Wikipedia).
Because birds-but-actually-humans (back to my initial point (fucking finally)) do be flying, having human eyes is a no go because those eyeballs would shrivel up and die.
Anyways I rest my case. I’m smart take my advice (nicky membranes + feathers-glued-onto-human creature).
Also it’s almost 1am and I’m a grandpa these days so my head dead and my brain shrivelled like raisin and that’s it goodnight folks I’ll be here whenever I decide to show up.
