Natural World: Super Powered Eagles (2020)
Revealing the science behind eagles - the most powerful birds on the planet. With 60 different species, each perfectly built for the kill, they've made their home along coastlines and in deserts, mountains and forests. This film tells the story of the eagle and discovers why it has been so successful. It follows a family of bald eagles as the chicks grow and develop. And from fishing eagles to snake eagles, it finds out how they have adapted their skills to conquer the world.
Welcome to BBC EARTH! The world is an amazing place full of stories, beauty and natural wonder. Here you'll find 50 years worth of entertaining and thought-provoking natural history content. Dramatic, rare, and exclusive, nature doesn't get more exciting than this.

that gliding shot at 3:41 is just majestic
Yes
Absolutely impressive, no doubt about it. Especially the way she took a less direct route in order to take advantage of air currents. But the guy was waving and flailing around which would have made it much easier for her (maybe?). They should have tried again with him remaining still. It would have been really interesting to see how much of a role movement plays in an eagles ability to identify targets.
and he shouted
yup... im sure they failed when they were not waving, probably took multiple attempts for the show.
I would imagine you're right and that it has a lot to do with it. We work the same way. For example, if you're ever stargazing and want to look for a meteor shower or satellites, the best thing to do is pick one single star in an open part of the sky and just stare at it... eventually if something does appear your eyes will immediately dart to it - almost instinctually without thought.
@@anonymousss8 They can not hear shouts from 2 km away
Most of the eagles targets are moving in real life. Whether he was moving or not humans couldn't have seen him. Still just as impressive.
I believe that eagle indeed had no problem seeing Lloyd, but his shouting ruined the experiment.
Agree
he didn't need to wave maniacally either.
Totally right They can spot a white mouse twitch a whisker in a snowy tundra I'm sure it can spot a man yelling and waving frantically on top of a hill 😂
@@Grandroboroxeagle : really? Okay let's make him happy, youtube
The experiment was made invalid as soon as he started shouting.
4:08 Why is he standing so close to him lol
They are becoming one
Love at first sight!
I saw that and thought about how I hate when people do that. You have to awkwardly create separation.
I think wind is very fast, so they can't hear each other
Weren’t you listening? We humans only have 200,000 cones in our eyes, they stood that close because any further and they wouldn’t be able to see each other
I wonder what Lloyd's near-UV signature looked like in comparison to the surrounding moorland. In addition to having outstanding visual acuity, eagles (like all birds) have a 4 types of cones (we have 3), one of which is sensitive to near-UV light. So while we saw Lloyd as wearing a drab green outfit which blended in well with the environment, it's possible that for the eagle he was far more conspicuous.
Yeah they can see scorpions as if they were neon lights
The eagle's powerful eyesight really makes me cry.
What? Why?
Bro, touch grass
BBC VIDEOS ARE ALWAYS INSPIRING & fascinating.
Eagles are magical 😍
There is always a catch with incredible power.
"WOOOO HOOOO... WHAT A BIRD YOU ARE!!!"
I felt that man's excitement and triumph more than any big staged Hollywood movie set piece. Actually pumped my fist in the air he got me so fired up. Magnificent
If an eagle can't see a human 2.5km away than they can't see mice when they're flying.. should've done a more impressive experiment
Such an impressive living being ❤️
Eagle has already 100× zoom before samsung s23 ultra 😂
Y’all are killing me. You finally start listing the episodes. Which is great. So I just went to watch this episode. “Sorry, currently not available” lol. But anyhow, thanks for the clip.
Fantastic video, great to see they're protecting the birdlife in Wyoming
3:41 now THAT'S beautiful
We went out to the river and a Canadian Honker spotted another Canadian Honker from across the river and flew over and chase it off, the river is 400 feet wide there, we were shocked their eyes are so powerful !!!
Canadian Honker ????
@@raintree3383 I guess that's why hunters always used to have a hard time getting them and they wear camouflage...
@@KurtElliott Hi I am asking what is a Canadian Honker ? I am Canadian and never heard that before....do you mean Geese or maybe Ducks ?
So glad they're looking out for eagles and other feathered friends
Fun fact: there is no limit on eyes. We can see anything as long as it is
A) not obstructed
B) reflecting enough light
and as long as we are not blind or with poor vision.
But we arent able to process everything we see in detail. We can see stars light years away, we can see the surface of the moon, etc.
Wow amazing ❤
So Majestically beautiful
Why is there no electrcity in the town?
Le Robot: There is an eagle flying high in the hills.
fascinating, not only with the bird, vision, and science but with the AI as well!
Agreed, this contained more information than I expected.
I think you mean CGI but yeah it was great
The natural world never ceases to amaze with its incredible abilities. The superpowered vision of eagles is a testament to the marvels of evolution and adaptation in the animal kingdom.
a testament to intelligent design and the living God
@@devon34654 Your reply is merely testament to your own unevidenced mythological beliefs.
@@Dr.IanPlect True, it is remarkable that through the marvels of evolution where sand eroded stones, for millions of years, to design this phone that we communicate through. marvelous!
@@pic18f452 tripe
@@Dr.IanPlect As to yours too.
It's not the doubling of cones per square millimetre that explains the superior vision. We know from human perception and photography that what counts is "linear" comparison and if we double the area resolution, then we get on SQRT(2) linear improvement. This is why we measure optical resolution (AKA sharpness) in linePairs per millimetre (since "ages").
In a digital camera, each photosite is scanned individually and each contributes to resolution. In the human eye, in the retina, cones are connected as vectors or lines, in what we see. We could call that a form of lossy data compression. At the cone level we may have 120 MegaCone resolution, but loads of cones being on one nerve reduces that by a lot. From the 120 per eye we may end up with 6 or less for combined eyes. Because we see in "live view" and also derive information from subsequent "images" or "frames" in movie/photography terms, the resulting apparent resolution is perceived as higher.
The important point here is the optical nerve. In the human case, it is very thin relative to the diameter of the retina. Simply put, we need to learn to deal with that vector information and our brains process visual information accordingly. In short distances, our auditive brain is much faster than our visual.
If we then compare with these raptor birds, AFAIK, they have each individual cone connected into the brain. This changes image processing from lossy compressed vector data of humans into lossless bitmap data - in IT terms. As the MegaCone resolution is twice as high, and the losses are zero, these birds end up in the Giga resolution of two eyes combined, rather than a measly dozen or less in humans.
The implication of a very thick optical nerve, potentially with the diameter of the retina, is that the eyes cannot move in their sockets and these birds need to turn their heads around instead. Which they do.
``If they spot an eagle they turn the turbines off`` Truly an alternative reliable source of power
Was wondering if anyone was going to mention what immediately came to my mind.
Just shows how little wind power is actually relied on.
If it was an integral part of the grid, no way could they turn it off!
Just imagine being at work, on your computer, then suddenly losing everything due to a loss of power, due to a potential bird strike miles away.
@@davidturnage3467 The power from a single source is never entirely reliable. This is particularly true from wind and solar, but is even the case for none internment sources like conventional hydrocarbon based powerplants where unplanned technical issues can disrupt production. It's how power sources are integrated which determines grid reliability, and while more is needed to maintain reliability with intermittent sources (storage, dispatchable generation, larger distribution of sources, etc.), if integrated properly grid reliability need not suffer.
What he said, basically it doesn't matter if your charger is unplugged, you can still use your phone because it has some battery left.
Awesome~👍
Thank you for sharing this video~🤗
That was awesome
'Spotted' ?
May be & may not & may be partially.
Sense of smell ?
Sense of feel & hearing ?
Commentator mentioned!
Seems the Eagle is able to establish wind flow pattern & directional & intensity of the wind current.
Overall, so lovely to see the reunion of the Eagle & Lloyd
Maybe not move next time
So awesome
Beautiful creature ❤
Wow
Last vid clip represents a human made engle eye where it can be better than that, how powerful the creation going and connected to everything
Love that Lloyd is so excited about his eagle lol
I like this truck! :D
It would have been nice to continue the experiment till the point of failure. Perhaps standing the participant 4km, 6km, 8km, 10+km away. Until we hit a sweet spot where the eagle can no longer see it's owner and aimlessly flies about. In these repeat experiments, it would be nice if the man doesn't make noise or motion (waving).
I wonder if the animals that are typically eagles prey, have evolved to learn to hide near wind turbines to use them as a defense from being captured.
Wow eagles can spot a snake or a mouse but can not spot a giant wind turbine
Of course they can see it. But…They don’t know what a wind turbine is or that it’s dangerous.
@@Me97202 , ah, yes, an ominous hunter: a wind turbine.
Wuauuu!!!! 😮😮 que maravilloso vuelo y una visión perfecta👌👌🤗me parese fascinante el tema de las aves me cautivan por su perfección de vuelo y visión. Y fantástico que hayan logrado de alguna forma manejar de forma adecuada el tema de los molinos de viento con respecto a las aves. Realmente un gran avance tecnológico par proteger su vuelos 👌👌😉😉
¡Qué interesante comentario! Estoy totalmente de acuerdo en que el vuelo de las aves es algo realmente asombroso y fascinante. Además, es muy positivo que se esté prestando más atención a la protección de las aves en el entorno de los molinos de viento y que se estén desarrollando soluciones tecnológicas para evitar su impacto en su vuelo. Esperemos que este tipo de avances sigan mejorando la convivencia entre la tecnología y la vida silvestre.
eagles are for me the most legendary animals
It took an indirect route because of the wind
Is this Dr.strange talking about PWingwins?
Now THIS is a great application for A.I.!
I'd ❤️ to do this for a living
such gorgeous animals :)
So cool!!!
Thanks for sharing.
I’m wondering if s high pitched sound coming from a turnine wouldn’t be a cheaper way to avoid bird collisions.
After all, if the don’t see the turbine, they can still hit it when it’s not turning
4:07 the guy as so poor vision he has to be half a inch away from you to see you
That little robot is using more power then its helping make.
beautiful video like it
Eagle: oh there he is. I will fly straight to him
Man: WooooooOooo girl Wooooo
Eagle: let’s just take the scenic route
Sooo he can see the bird and yell at it but he is surprised that the bird saw him?
Exactly! Hilarious!
I’d love to go “wheelin” in Scotland
Very considerate! However, isn't it more productive to install loudspeakers on top of wind turbines to play some kind of warning sound instead of shutting down turbines when eagles are spotted in the area?
Please provide us the full show of The planet by Brian cox it didn't available in India
Shouting and waving non-stop . Not hard to find!
Well, he was talking and yelling… and waving instead of staying still and quiet.
What if right after the bird takes off, the professor guy turns off his radio?
That's the way high-tech should come to their/our rescue! Glad to see that!
this is not so related, but in 4:09, why did the man in green have to stand ridiculously close to the professor?
Did anyone else think that ideniflight robot at the end looked a lot like Wall-E?
4:09 that seems so awkward being that close.
Curious how bad would it be to install ultrasonic whistles on turbine blades?
Saving the environment one dead endangered bird at a time.
4:09 while his eagle can find him 2km away the bird handler has to stand 2 mm from the person he is talking to
The last scene was awesome. When artificial intelligence working to stop turbines before hitting the eagle 🦅
It's amazing how animals in the wild have to fight for survival every day. The story of the warthog escaping from leopards and lions is a testament to their resilience.
What kind of test has him waving his arms
would be cool to see more of the eagle vision and less blalblalbalblalbalalba
I see things on timber floors that I try to point out to others and they don’t see it lol even my boss who’s done it over 20 years. Eyes are just trained to see scratch patters sanding floors but my eye sight is normal or less then normal since my eyes are dry a lot from weed smoking
Real Byakugan.
Nice 👍
A group of 38 eagles was spotted where i am from in Meghalaya India, a species with the word Himalayan in it and was said that they're almost extinct.. i think they are hungry for food and raiding meat shops, please if there is anyone who have the power to help these magnificent creatures, can you please help them as i know the people here would rather hunt them for food than preserve what we have left
❤❤❤❤
Kissey Kissey
The energy the gain from the turbines they use to power the artificial intelligence so the eagles don’t hit the turbines.😂😂😂
I have spotted a pack of wolfes at 1.5km. Saw them as something that could have been a wolf. An eagle would have identified it. So, also humans are quite sharp eyed.
@Jan M where were you when you spotted a pack of wolves
What I would find interesting is the question if the eagle really can see that far or if it is just more like a sense in his view.
Why on earth do they shut the wind mills off? Where I live there's a wind mill and the big birds have tons of fun in the tip vortex. Sometimes there's a whole flock of hawks there. And crows.
That is some incredible AI stuff.
Love seeing AI creep into applications everywhere
Pretty sure screaming didn’t help hide him
Glade that some people can think instead of paying attention to other instead of themselve and looking forward in their live to make a different in their communities and show the ability to learn and give wisdom in their area right!!!-) people????
8 times Vision than a man.
She is in Scotland and she can she the crimes against humanity being committed against the people in Palestine. It's pretty amazing
@@jaimedelgado7529Arabs are doing fine. No one is trying to slaughter them into extinction.
@@jaimedelgado7529 oh my.....
@@jaimedelgado7529 Yes, turn an interserting look into eagles into a political thing. I appluad your bravery.
Yes Sir....
me at 3am
4:09 why are they standing like that?
Maybe to block the wind

Very interesting. The technology could be used to counter drones as well?
I spy with my little eye, something beginning with L.
If an eagle can make honey for the queen then im sure it can see that far
Eagle vision is above humans perception.
would've been cool if he was shouting and moving surely made it easier
Divine animal kingdom....
All natural.
4:10 the entirety of the vast empty scottish highlands... and that doofus gotta stand 4" away from him
Its pretty good in Assassin's Creed...😊
I think your yelling might have aided the bird a lot more then her eyes...
i want a pet eagle
Why not have them emit an electric pulse that would shoo the eagles away instead?
His shouting and waving ruined the experiment.
they probably tried it without waving and shouting and it didn't work
