  • Hey, it's me Destin

  • Sorry for the vertical video there. 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

Hey, it's me Destin
