  1. Great video but please, next time you hold a live bird, don't grip it around the chest. Birds' ribcages need to expand in order for birds to breathe. Doves are incredibly docile normally but you can tell this one is in distress because it can't get any air. Just a heads-up.

  2. Hey Destin, you should look at the Bee Humming Bird. It hovers by pushing air down on both the front and back stroke. At least, I think that's right. Would be amazing to see one of those in slow mo.

  3. & they said no one created all these things. ..I wonder how something that was well thought wasn't created…just boom bang appears in such engineered way. WoW . there has to be someone behind it all ..

  4. I don't know about other birds but pigeons primary wing feathers ,ten on each side , are actually individual wings them selves. On the down stroke lock together and on the(back) up stroke unlock to provide continuous lift. If you watch a pigeon take off the do not lose any altitude as the wings sweep backwards the continue to go up . They are even more amazing than you know. Being pray for everything They Have adapted into the most amazing masters of flight . Homing pigeons can have average speeds of 60mph over hundreds of miles nothing comes close . They are the true masters of the air.

  5. Do you like somebody to tie you up, and show you to the crowd while he is explaining how human organs work?
    If you dont like that, so does the bird

  6. This is gonna help with my flying project a lot…

    I promise not to sue you if I break every bone in my body by trying to fly.

  7. Hello Destin, thank you for the knowledge. I have a question for you: If some insects, some mammals and some birds can fly, would some people be able to fly by their own muscles power with the wrigth wing-suit ? My answer is yes and I am doing this project

  8. they have wings which can function like a helicopter blade AND like the  stiff wings of an aerofoil, reciprocally and  quickly

  9. now you know how feathers and wings   work- so you can make your Daedalus wings and jump off the roof at the parking garage

  10. Why don't birds use the return stroke also to create thrust, like in swimming using a flipper on the foot or a like a Chinese folding fan.
    And are the birds changing their body direction to direct the thrust for lift and then thrust for forward flight, assuming that they generate thrust only backwards relative to their body ?

  11. I was sure this had to be the case; brainstorming about having wings for human flight, it occurs that the wings must slice through the air on the backstroke, same as our body does naturally whilst treading water.

  12. This would be amazing to see Hummingbird wings reacting the same way… I'll have to search for that.

  13. Hey Destin, I thought you noticed that delamination of the feathers in one of your previous videos….. “the bird take off”. Glad I noticed that😅. So your videos and other science channels are changing my perspective 😄

  14. We continue to learn more about complex flight from watching the birds. Check out some of the latest NASA studies on complex wing designs.

  15. I fly. Paraglider. And would love to developed a flapping technique that will enable me to gain altitude. I do a flap process when landing but it is to reduce my forward speed to do as birds do. Not able to life the wing up and vent air from above through the wing but will keep watching for development of the sport.

  16. On another video I commented how impossible it is for any application of the theory of evolution to explain the smallest of creatures' design! The DNA that defines every creature by internal design every cell contains has no possible origin outside pre-determined purpose for each creature. There's no exception, either!

  17. As with rowing a boat, one feathers the oars on the forward (non power) stroke to save resistance with the air against the oars blade.

  18. This is really useful for artist and animators too. Thank you for sharing. Definitely something more to think about and appreciate the next time I go hiking and bird watching. Love your homing pigeon too!!!

  19. Thanx, very nice video, the thing I would like to know is the anatomy of a bird wing that prevents it from washing out (that is the mechanism that prevents the feather ends to ride up under the stress of the down stroke.)

  20. Dude u killed that pigeon at the end of the video! It didn't last trough the end of the following day if it was lucky. Let it go… Lmao! A predator got that thing 110%. U let a banded all white pigeon just go. I hope it was a homing pigeon and it lived a couple blocks away at ur buddy's house.

  21. Birds should not get their wing its wrong its not normal they dont clip their wings in the wild wtf or humans doing

  22. idiots saying he pulled a bird from nowhere yet at that moment there was a video cut where I believe he had to get the bird from its cage and continue shooting the video

  23. Thank you, It makes me try to imaging how Pterosaur flight might compare. As their wings were made of one piece rather than the multiple feathers of a bird wing, there would clearly be some important differences. Any ideas?

  24. Hee Destin, my physics friends assure me that the Bernoulli explanation is only tiny fraction of the story. There's a better explanation.
