Though the common ancestor of all modern birds could fly, many different bird species have independently lost their flight. Flight can have incredible benefits, especially for escaping predators, hunting and traveling long distances. But it also has high costs: consuming huge amounts of energy and limiting body size and weight. Gillian Gibb explores what makes birds give up the power of flight.

4:09 You just couldn't resist could you TED-Ed!
Just trying to emuse. :)
I BELIEVE I CAN FLY >:D
TED-Ed ugh
I didn't know these people had jokes
TED-ED We saw what you did there! Toucan play at that game!
Other birds "swim" in the air, penguins can "fly" underwater.
Lol
air is a fluid so this is quite right
No way, good call
whats interesting is there are birds that utilize the same idea by mixing it. they start in the air, dive into the water to catch their prey and fly back up
Suneil Parimoo yyyyeeeessss
Because they're playing in Survival Mode

What about elytra?

The TH-cam video of the same name is sad
I just had flashbacks......
cuckoo head 3:05 Ohhh, how sad 😢.
Not ur profile tho
@@vol10O000 yes, I absolutely agree with you.
Flightless birds' responses to predators:
Cassowary - I will gut you and then punt your corpse into next Thursday.
Ostrich - Only part of me you're eating is my dust.
Kiwi - What kind of dipping sauce would you like?
Tbf, several species of kiwi are quite capable of defending itself. They have powerful kick and sharp claws and with a bit of bluff, can even repel stoat.
@@waranontwiwaha9385 r/woooosh
Kiwi:🤬🤬😡😡😡
@@raptorzilla0710 , dont you wosh the interesting facts teller you dunce
Kiwi: _kicks the predator in the jaw_ “TAKE THAT FOE! Anyway, how was your day?”
Their legs grew *THIICCCC*
SBBwasaight Vuong I am so happy you commented this 😂😂👏🏾
i was the exact same thing when they talked about the big birds evolution
maybe they are flying when we are not watching...

Top 10 anime plot twist of all time
*Chicken has left the chat*
Roosters are named after what they do best.. roost. Chickens for centuries a very good at roosting and in nature this involved jumping, flying up into the trees and gliding into other trees to avoid predators.
Many don't think Chickens as flying birds because they don't fly long distances.
Don't think chickens are a bunch of chickens. They can get quite vicious if they when need be.
Chickens can fly , I just test recently and they flew away but on very low and short distance only
Chickens can fly, albeit their flights are very short.
Chickens *can* fly but they can’t fly far, which is the reason they don’t fly away in your yard
*Eagle has joined the chat*
Just one question; Since the birds can quickly lose their ability to fly in a few generation in absence of threats, how fast can they regain that ability?
That's an interesting question
as far as i understand, every bird species of today has once partially lost the ability to fly then re-gained it later, once all the flying birds had gone extinct during the K-Pg event due to the loss of tree-top environment and they filled the flying niche
I don't think that ever has happened
It might be possible but it'll take much longer than how they lost the ability since there should be a much longer process for anatomical changes...
Thet can't
0:28 That has got to be the most pissed off looking bird I have ever seen.
Well it the most deadliest bird ever and it my favorite bird
Ever see one in real life? No, because you’d probably be dead. they will maul you like a freaking tiger with claws that are probably twice as sharp. They are the most dangerous bird on the planet.
Flarbargason I saw one in real life at the zoo
【InsertNameH3re】 fair point, so have I. But those are far more docile because they were born in captivity. If they just dropped a wild one in the little fields you see them in (or at least where I saw them) they would definitely get out and go on a rampage.
Just saw it literally days ago when I visited Sydney zoo! It looks the same lmao
Evolution giveth, evolution taketh away
Facts in Motion I like your videos
No evolution occurred it's all creation and have a creator of life it's God
@@jasonni183 yes, evolution is as saying the earth is flat. Everyone believed that previously. Or that the universe had no beginning. All proven false and it correctly stood in the Quran. I get so sad that everyone believes evolution is true (yes "believes" because they're deluding themselves and not actually thinking about it) and then in a hundred years maybe when it's proven false everyone will think "how could they think evolution is true?" That's how people now think about people which thought the earth was flat. And evolution doesn't even explain where we come from. We also have DNA repair mechanisms, so how can errors lead to better change? Do people really think that we created ourselves? Can something nonexistent create itself? I hope they'll all be guided inshallah. Also, DON'T start a discussion with me now. Think for yourself.
@@Cyber_One+ No, and no. We have found fossils of our ancestors. We have found evidence within the plates of the earth. Evolution is real, whether you like it or not.
@@kayelynnphelps8676 No it's not, I said I don't want to discuss this, because every single time it starts from the beginning all over again with the same wrong claims. And that's no evidence, the fossils say nothing, and they even have to be manually reconstructed, because only tiny little fragments of them are actually recovered. And guess what? They completed a human skull fossil with the help of a chimpanzee skull. Yeah. Think about that. I'm constantly thinking about this and evolution is most definitely wrong. I'm not going to say anything anymore. God gave you the entirety of knowledge to the palms of your hand. Use it to find the right way. This is your one and only chance. You came here because you wanted paradise, this is the test. If God were to give direct evidence, there'd be no test and no paradise. Hope you'll get guided soon.
Please make a video on how the continents were formed.
Hi Nafiz, here's one on how the North American continent was formed: ed.ted.com/lessons/how-north-america-got-its-shape-peter-j-haproff and here's one on what happens when continents collide: ed.ted.com/lessons/what-happens-when-continents-collide-juan-d-carrillo. :)
I really do like Penguins, they are cute.
Same
Did you hear about all of the little fairy penguins that got mauled by dogs in New Zealand?
They also said the n word
Person: On a scale of 1 to 10, how much do you like penguins?
Me: How to count past infinity
batmanfanforever08 but theyre gonna melt you with their eyes!!!
4:04 Just like Naruto!
Study shows the "Ninja run" actually generate more air resistance than regular sprinting.... so that is why you don't see it on Olympics... Plus human arms are not as effective as bird's wing when steering. (Ostrich sometimes does use their wings like air brakes/oars/rudders to turn)

is it just me or the voice of this person is my FAVORITE among all other lecturers? just calms me down while i learn something new 😊
yes! my absolute favorite narrator on this channel by far
@@audreydeatherage2131 same!
Dodo bird is one of my favorite species of flightless birds
You won't ever be able to see one in real life.
And Penguin is mine 🐧
I prefer cassowaries. Dodos are wimps.
I don't know but I love kiwis.
@Bipedal being food is what made them go extinct
Don't change the person who reads the script. The narrators voice is quite relaxing.
Thanks for making such amazing content free for all of us, and helping in making the world progress. I'm trying to do the same, but no where near you guys.
I always enjoy Anton Bogaty’s animations!
and Adison's voice!
is he rich?
who?
Anton
My flight school in New Zealand have these flightless birds studying pilot licenses, and we are training together to fly in the skies after graduation.
I love these videos! They are the perfect length. Entertaining and full of useful knowledge as well. Great animation and commentary
Becaue *R Kelly* hasn't taught them how to BELIEVE they can!
Ah you are mistaken Phil, it is in fact a classic!
Greatest song ever written if you ask me.
I'd have to agree with you. It's a life-changer of a song.
He’s too busy molesting and caging young girls.
Fancy seeing you here
“Why can’t some of the birds fly”
Penguin: *Ok next video should be: why can’t most of the birds swim*
The illustrations here are so cute!
I freaking LOVE this style of animation! All the animals look so cute 🥰 🥰
You are so funny and creative please keep doing what you're doing because you're doing it amazingly
It's tEd eD..
kiwi are so adorable and dodo are just like "Dude see me or get ready to get rekt"
Title: 'Why can't some birds fly?'
Penguins: ''And i took that personally''
"Never try to declare a war on flightless birds" -Australia
A special shout out to the graphic department guy! This animation is genuinely funny, interesting and yet educational.
Why don't chickens fly?
*Because their ancestors knew that they had to be a part of KFC in the future*
It says the common ancestor of all birds could fly. If you go back a bit further, the common ancestor of all birds could not fly. This ancestor was a dinosaur.
This was so well animated and explained! KEEP up the good work :)
펭귄과 키위 새 등은 날개가 있지만 날지 못한다는 것이 항상 이상하다고 느꼈는데, 이제 이 동영상을 보고 알게 되었습니다. 이런 동영상들을 보며 제 지식이 점점 더 늘어가는 느낌입니다.
These videos are great. They're so insightful, with amazing narrators and good animation :)
You shoulda mentioned the giant moa. This bird was 12 feet tall and weighted 500 lb, and used to run around NZ some 800 years ago until the Maori killed them.
The madagasy elephant bird was a little bit bigger thou
@Martha Speaks You should really be focusing on the TWELVE FEET
@Martha Speaks "
preposterous!"
I thought European settlers killed them?
날으는 것의 대가들 막대한 양의 에너지 소비, 몸무계외 크기 제한등 나는 것도 단점이 있다는 것을 생각을 않해 보았는데 단점도 보게하는 넓은 시야를 형성하게 해주는 좋은 시간이 되었습니다. 정말 감사합니다.

Ted-ed is the best educational channel on TH-cam.
Even if penguins can’t fly, their still my favorite animal.
Mine too :)
They dont need to use ability majority of others use to be great, i like them too
This channel is just all of my childhood questions
Loved the way how penguins just dropped themselves into water 😂😂
Baby penguins, also called pips, are so cute. They’re all covered in fuzzy gray down
RIP, Moa and Elephant Birds :(
What about the king island emu ? :(
Biggest bird ever lived: exist.
Humans and their pets: hi
So basically flightless birds use their wings to Naruto run...
You guys never disappoint us at learning :)
I'm early so it's time for a joke:
Who's a penguin's favorite relative?
Aunt Arctica!
I mean could you imagine looking up at the sky and seeing a penguin flying by?
The animations are so cute.
In NZ we have the smartest native parrots, the flightless ones are amazing and the flying parrots are inquisitive and problem solvers
I LOVE TED! So clean, so nice. Just perfect!
Very interesting !
Thanks for including New Zealand birds!
Land dweller benefits: you can run fast
Flying benefits: you can fly.
Road runners: choose both.
Andrew Glinski meep
I have gained alot of knowledge. Thanks to all patrons who supported Ted.
Let me rephrase the question.
"What if all birds can fly?"
Imagine that ostrich fly over you.
"They traded flight for size"
Secretary birds: I'ma let yall finish 😂
After watching this video about flightless bird,
now I wonder if they can make a video about Platypus...
also wondering, what's the different between emu and ostrich? I thought they kinda same...
More or less, emus and ostriches have different ways of incubating their new born offspring and emus are farmed for their meat and oil. Ostriches for their feathers.
Ostriches also have large eyes.
Just from a quick google search, dunno if it's true.
Ostriches are idiotic
Australians haven't lost a war to ostriches yet
You mean 'Perry' 😌
They are kinda the same
They are cousins
I'm not sure what the specific differences are, but the ostrich is bigger and they live in different continents, so even if they have a common ancestor they evolved differently
My rooster: *jumps off the table thinking he can fly* HIM: *falls on the floor 😃*
"They may be flightless but they're still winging it" i like to joke and or pun
kiwi are nocturnal and they're pretty big (other than the small species)
That is so interesting and presented clearly and with humour. Love it.
My umbrella cockatoo is flightless by choice. She's middle-aged and set in her ways (I adopted her 9 years ago). She picks her feathers and seems to intentionally chew off her primary flight feathers. Even in situations where she would be able to get some lift she chooses to walk or yell for human transportation. She is extremely lazy and dramatic so I have to assume this is a conscious decision she's making. I love her.
I love this channel so much, I learn so many things about stuff I normally wouldn't care about!
I like this art style!
When I was 11 I saw a duck flying so long I was amazed. I thought it would fly to the sky xD
0:35 question 1
they dropped out of fly college
Love Anton Bogaty’s animation
33 Creationists disliked the video
"They may flightless, but they're still winging it" ahahhaha XD
1:26 home alone
one of the most soothing voices EVER
I feel like penguins can’t fly because they are overweight.
Yep
Is the constant commenting everywhere boosting your channel a lot? Genuine question..
Ted Ed I love your animation please make a video about the life cycle of a plastic bag
Because they forgot to learn HM Fly
I see you're a Pokemon fan as well.
Some Videos in ted ed like what causes depression, my mom doesnt want to watch those kinds of videos even tho i wanna learn something about how it affects our life, im like wtf why are u stopping me to watch this kinds of vids? it doesnt do anything to me
Hilarious and Good method to learn
Ted-ed:emus,ostriches,kiwi birds and penguins is are flightless birds
Chicken:im a joke to you?
They can fly
3:09
The animations are so cute!! The topic is about flightless birds going extinct as well.
Like, look how adorable that cat is? 2:44
*has FarCry3 cassowary attack flashbacks
There are two types of birds in this world: those that decided to give gravity the middle finger, and those that took either swim classes or track events...
*You can't defeat me I have the high ground*
Great video! Only con in my opinion was that cute looking stoat at 2:52 . Stoats are such vicious animals!!!
Do not forget the DODO.

By watching videos like this I have improved a lot in my English
This is a method of getting your pet birds to talk.

Give them chilly or hot pepper to eat. Once they eat it, they will be able to talk by copying u.
So sad that so many public schools in my home state can't have this video in class do to the talk of evolution. :(
Good animation as always!
Thank you for pronouncing "emus" correctly. Many Americans don't.
Help me
Because an evolutionary trait was successful in breeding. Similar to how some people don't need to work, yet keep breeding, and some people are genius' and don't breed. Traits that carry on through generations of survival, become dominant, not because they are valuable for survival, because they lucked out and survived.
Maybe they can and they're just hiding it?

The kiwi is reminded of flight. I can hear his silent screams.
