I was recording for the Instagram story So I caught this bird with my hand and I got to thinking about it It's kind of a shame to have a bird and let it go and not film it in slow motion So, that's what we're gonna do. Alright, this is my daughter's butterfly Thing. Where you at little bird? Hey calm down buddy Calm down, calm down There you go calm down Okay, let's hold you where you don't get hurt There you go. All right. Let's go let you go. What do you think? So I've always been fascinated by birds their wings in particular. You see that the primary feathers one, two, three, four, five six, seven, eight Nine, I thought they had ten primary feathers. Maybe they do and then these are the secondary feathers And then the feathers around his eyes It's really cool. He's scared so we're gonna try to try to get him out of here real quick He's wanting to fly away. I know this isn't like a super in-depth smartereveryday video But this is just a target of opportunity something to learn really quick What I want to know is when he takes off if his tail feathers are correctin' immediately or it has to wait until he's moving in flight before he starts using those. We probably Won't see that because we literally have one shot to do this But I'm really excited. Did you see his eyes like the little Feathery things around his eyes. I've never noticed that anyway, he's getting tired. We got to let him go Alright here we go. Releasing the bird Three, two, one That was fast. All right, let's look at it. I mean we we've probably just got the launch but I like birds All right, I set out to make a cute little video of a bird hopping out of my hand But I actually learned a ton from this footage. Number one It's clear that the bird hops out of my hand, and I've never thought about that I'm sure that's just common knowledge to ornithologists, but for some reason I always thought birds just start flapping to fly And he's hopping why would they not use their legs to get further away from the ground? So their wings don't hit the ground or my hand or whatever. That's just cool. I've never thought about that number two I think it's neat that he points his tail towards the ground on that hop And I've got to believe he's doing that to reduce the vertical component of drag so that he can hop farther Another thing that happens is on the downstroke. You can see that his feathers are together But his feathers delaminate to reduce drag on the backstroke, we've seen that in a smartereveryday episode in the past It's fun to see it again here number four. It's cool to see him transition that tail from being pointed down. He raises it So he's getting ready for horizontal flight so that transition from vertical flight to horizontal flight He straightens his tail out to get it in the game. He's getting ready to make corrections in horizontal flight I think it's really cool to make your own observations because all this probably exists in a scientific paper somewhere But it's fun to actually see it for yourself and try to understand. I'm gonna be looking for these things Every time I see a bird take off from now on. Alright, that's enough of this bird. You want to see my garden? These are my sunflowers. I grow them for All the ladies in my life My daughter my mom my wife While we're here, you want to see my corns-es? My corns-es are bad. I think I overwatered them. These are my corn-es These are my corns-es and Right here look at this bad boy. Look at it. Beautiful It's a good-looking melon right there anyway It's a simple video. I hope you enjoyed it. I'm Destin. You're getting smarter every day. Have a good one. Bye
