Just How Good is Eagle Vision? | Natural World: Super Powered Eagles | BBC Earth 

that gliding shot at 3:41 is just majestic

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.

Came for the eagle and I'm left with hope for the future. 👏🏼👏🏼👏🏼👏🏼

Shout out to the man that counted how many cones a human have in the eyes. ❤

I believe that eagle indeed had no problem seeing Lloyd, but his shouting ruined the experiment.

Eagle has already 100× zoom before samsung s23 ultra 😂

4:08 Why is he standing so close to him lol

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.

Even I would find Lloyd. Waving and shouting😂

What a majestic animal.

The eagle's powerful eyesight really makes me cry.

Eagle having superpowered eyesight and me who have glasses

The guy's shouting ruined it, also him waving his arms about.

I believe that Lloyd waving and shouting after 15 minutes waiting without results.

"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

Neat way to use AI. Also nice explaination about the wind turbines, I had always wondered why birds flew into them.

They make a great argument for tearing those wind turbines down. If I ever saw a bald eagle get hurt by one of these I would take direct action.

I want a eagle I love them there my favorite 🦅 ❤

BBC VIDEOS ARE ALWAYS INSPIRING & fascinating.

There is always a catch with incredible power.

Thank you so much for the beautiful technology to save such a magnificent bird

Eagles are magical 😍

If you're testing for eye sight maybe the yelling is counter productive if she can hear you too.

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

@1:57 The level of technology that birds employ so naturally and effortlessly … is mind-blowing.

It's "Johnny 5" from 'Short Circuit' 😊

Such an impressive living being ❤️

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 !!!

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.

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.

So glad they're looking out for eagles and other feathered friends

Fantastic video, great to see they're protecting the birdlife in Wyoming

A BBC tem sempre vídeos que nos fascinam ...isto é simplesmente incrível... de uma linda espécie que tem uma visão invejável e fenomenal! Importante...o projecto ...para salvar esta imponente ave que dá uma leveza aos céus!!

How do you even record suck amazing views?! Magnificent

Why is there no electrcity in the town? Le Robot: There is an eagle flying high in the hills.

3:41 now THAT'S beautiful

@5:37 makes me incredibly happy. And I’m happy to pay for it.

``If they spot an eagle they turn the turbines off`` Truly an alternative reliable source of power

fascinating, not only with the bird, vision, and science but with the AI as well!

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.

I was so astonished when I saw wind turbines which they shut down when they detect bird who can fly. This is such a friendly environment technology that every company must include themselves.

It still astonishes me how big they are compared to how little they weigh. lol

Nature is amazing

So Majestically beautiful

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.

Love that Lloyd is so excited about his eagle lol

Wow amazing ❤

4:09 The guy in green is so excited by his eagle hear him shout, he has lost sense of personal space.

It's not going to happen in my lifetime, but when the day comes where doctors can transplant a complete eye, people are going to want to have eagle eyes for real.

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.

You clever bird. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)

3:44 that goes hard

'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

Awesome~👍 Thank you for sharing this video~🤗

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

Maybe not move next time

2:24 😮 great guys .. eagles eyes strong ...

Wow eagles can spot a snake or a mouse but can not spot a giant wind turbine

eagles are for me the most legendary animals

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).

Now THIS is a great application for A.I.!

Is this Dr.strange talking about PWingwins?

That little robot is using more power then its helping make.

We don’t know if the eagle spotted him as soon as it got out of the cage or a few hundred yards down the line. It’s hard to say how far she really spotted him from.

Sooo he can see the bird and yell at it but he is surprised that the bird saw him?

Wow

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 👌👌😉😉

4:07 the guy as so poor vision he has to be half a inch away from you to see you

they both have fantastic vision, but I always thought the phrase was “eyes like a hawk” or “Hawkeye”. Never heard eagle eyes

That was awesome

Incredible, the flying object detector AI is amazing!

Eagle: oh there he is. I will fly straight to him Man: WooooooOooo girl Wooooo Eagle: let’s just take the scenic route

So that's why 90% of wind turbines never spin.

I'd ❤️ to do this for a living

I’d love to go “wheelin” in Scotland

What a beauty

So awesome

*Eagle flying at 100kmh strikes a turbine fan* "Thanks for turning it off mate, that helped"

Burung elang itu sangat tajam sekali penglihatannya

Beautiful creature ❤

I like this truck! :D

It took an indirect route because of the wind

That's the way high-tech should come to their/our rescue! Glad to see that!

At 5:47 is an early relative of Wall-E, looking out for Eagles! ❤

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.

I was just comparing eyesight's with an eagle the other day. He could see further than me. And he said he was telling the BBC that he could

Excellent 👍🏾

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?

Well, he was talking and yelling… and waving instead of staying still and quiet.

Shouting and waving non-stop . Not hard to find!

So well made my goshhhh nyc

The eagle eye designer is the Almighty.

What if right after the bird takes off, the professor guy turns off his radio?

I just ❤🤍💙 #EAGLES🦅.

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

Seeing is one thing but hearing is completely different. By yelling you ruined sight test

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.

While me needing of a glasses to read letters

Saving the environment one dead endangered bird at a time.

i want to know why the eagle knew the seemingly longer route was faster because of the air streams
