What's the title of this wonderful music please? Thank you!

[qqqquito]

@Nonnel81 The music is "Silence in Heaven" by Stephen Jacob.

This video is the seriously the best video in youtube.

i love this as i feel like building the monument.

Sometimes they fly for a long time because they are afraid to land. Not the touch-down, but if there is not enough wind, it is almost impossible for them to take off from the flat ocean...

[gerlown]

so peaceful, so albatross!



[Graverobber94]

those birds has got a damn size

[IrmaPortsoy]

This is a wonderfull video . Absolutely captivating . Wonderful

[mrcantstoplol]

this video is the best. thanks man!!

[Azelf3]

I wanna be an albatross, saves money on air tickets.

[everythinguwanted]

He sighs, "aren't there any aviators watching this clip"?

[everythinguwanted]

BTW, this is one beautiful piece of art.

[everythinguwanted]

Could someone please explain to me the aerodynamics at work here that enable seabirds to fly at length without flapping their wings. It's more than ground effect (although that magnifies it), the sea is flat, so there can't be an updraft, the albatross is found in cold waters so it can't be thermal, the only thing left is the ocean winds, which begs the question, why couldn't gliders replicate the actions shown here?

[msf60khz]

@everythinguwanted

The wind blows slower close to the sea, and by varying its height the bird can extract energy from this situation. When it swoops low it is able to make progress to windward, and still have momentum to regain height for another swoop.

[everythinguwanted]

@msf60khz I read two presentations by aeronautical engineers back when I posted and know what you suggest is approximately what was concluded in those papers. Apparently I'm not bright enough to see how they can make headway against the wind while gliding low with a tailwind at their back. Only the principle of dynamic soaring comes close to explaining it and I've watched videos on YT and still can't grasp it. I've resigned myself to enjoying the birds and stopped worrying about the physics.

[msf60khz]

@everythinguwanted Imagine that the bird is high and is being blow along backwards by the wind. By slightly pointing down he can glide efficiently, but if it is foggy he does not know he is going backwards. Now he dives down to water level. He gains a lot of speed and also finds himself in calm air - but he thinks it is a wind from behind him. Now he makes progress to windward and gains speed enabling him to climb up again.

@msf60khz Dave, lets give this bird some flight instruments. In your example lets say the bird has an indicated airspeed of 20kts but his gps groundspeed reads minus 10kts 'cause he's going backward. He's flying a heading of 360 and the wind is right on his nose from 360. He descends to the surface in a 30 deg dive and by the resultant vector of gravity plus lift he overcomes the wind and gps reads plus 10kts into the wind. When he encounters calm conditions at the surface (part 1 cont)

[everythinguwanted]

@msf60khz (part 2 cont) and pulls out of the swoop, his IAS increases to 20kts and = gs due to calm air. Due to the compressability of air within 1/2 wingspan, he can ride this cushion for x # of secs, then the air and gs start to tail off.

Here's where my mind goes numb. When the bird senses it has only enough energy left to climb for another go, all the forward motion is converted to the ascent where that 8 foot wingspan acts like a sail and he is again flying backwards. (cont to part 3)

[everythinguwanted]

@msf60khz (part 3 cont) The bird starts off flying backward at 10 kts, flys forward between 10-20 kts and returns to a condition of a stabilized hover (glide) while achieving a negative groundspeed of minus 10 kts (these numbers are totally imaginary and dont represent any calculation). So therein lies my dilema. But to be fair, I'm not entirely sure I could explain how sailboats can sail into the wind either, lol. I must have damaged DNA somewhere in the area of conceptualizing thoughts.

[UnkleSi]

@everythinguwanted I agree! I REALLY struggle with the physics of how they can keep getting 'energy for nothing' on a flat ocean. I have experienced DS myself with my RC foam glider, it's relatively 'easy' to do given a large hill. But with a flatish ocean?? Don't know how that works! The sailboat thing is relatively easy, it's just a lift vs drag vector with a resultant which can be angled slightly into the wind. I still cannont get my head around the 'flat ocean' Dynamic Soaring though.

[everythinguwanted]

@UnkleSi I think I wore out Dave @msf60khz...I understood what he was saying but cant wrap my mind around the impractical nature of it. Its hard dealing with a numbskull like me. As for DS and gliders, that is the most fascinating thing I've ever seen...I think the WR is 382 knots! I've heard being a sailor makes you a better aviator and I can see that now. When my 'puter quits having brain farts I'll put a couple links to Wiki for those engineering papers.

[ottidio]

meraviglioso

[UnkleSi]

I've watched this video so many times now! Watching them fly is simply incredible.

[XantinovaX]

Wow.

Haha, I never though of it before but I agree with sundaywino.

[belask]

aah what a life.

[wayneleon100]

As I mentioned, fish hooks are a danger, as the Albatross swallow the hooks and choke to death. People must write letters of concern to all those countries involved in fishing within the Southern Ocean, leaving their pollution, plastic bottles, and other rubbish. The Albatross are an endangered species and will soon become EXTINCT IF ACTION IS NOT DONE NOW TO STEM THE FLOW OF POLLUTION WITHIN THEIR ENVIROMENT!

[wayneleon100]

Albatross virutally live in the sky. The only time they land is when they come down to breed. Otherwise, they spend their life gliding over the Southern Ocean. Albatross are an endangered species and really need our help. Countries who fish in the Southern Ocean, leave their discarded rubbish within the waters.This pollutes the water which poisons the fish, squid, octopus and other animals that the Albatross feed on. This leads to death of the birds. Fish hooks too are a danger.

[Mrsbogglewart]

You got loads of hits by people 'thinking'  it was the real best seller version:(

[qqqquito]

Awe-inspiring birds and fascinating music!!!

[2efnbad]

H2oreactor.

Common Swifts: Eat, sleep and mate on the wing. They land only to brood or feed young.

You owe it to yourself to be informed before commenting. Otherwise your comments have no value.

[UnkleSi]

Wicked! How efficient they must be aerodynamically to be able to glide for such extended periods without flapping.

[WuManGroup]

someone told me these birds can fly for five years without touching land, i find that extremely hard to believe

has anyone heard of these birds being able to do anything like that, or any bird for that matter??

[h2oreactor]

no other birds other than albatross can do sustained flight, they 've mastered the art of flying and gliding.

[wjfredericks4]

Albatross can fly for thousands of miles with out ever flapping their wings. Actually they can even lock their shoulder so they don't have to use their muscles to hold their wings. Its called "Dynamic Soaring" they are performing this maneuver at the following times in this clip: 0:41 0:59 1:17 1:30 ...

[dumoulin11]

from many years of reading about these birds I can tell you that it seems quite likely if you consider that they can rest on the water surface like ducks. Also, they have some quite neat adaptations in their wings to "lock" them in place, thus reducing the strain almost completely.

absolutly beautiful

[ahlc]

Wonderful, thanks for sharing!

[JoachimMink]

Super schön!

[ilusiones]

maravilloso

[acqua313]

Thankyou!

[gunsandtanks]

Lovely bird!

[croscoe85]

I love the Albatross. Very inspiring.

[norad73]

amazing

[Romanacer]

at 2:05 i get goosebums...

[selknasrai]

Staggering and beautiful.

The music suits well, but it sounds like the music from the Sims.

Not meant to be disrespectful.

[sundaywino]

If theres such a thing as reincarnation I want to come back as an Albatross.

[ssech6]

Amazing!!! has no equal on flying it is the ultimate flying bird, the aerodinamics are unmatched and yes I would say it warms my soul,thank you for posting.

[sundaywino]

This bird surely has to be nature at its most perfect. Surely there is no greater flyer?

[jelleoelle]

this bird is the master of dynamic soaring

[windshield48]

It`s a great majestic flight....and the music

fits very well....Thank you so very much for sharing this beautiful video! It is uplifting in every sense!

[wisdomlikesilence]

Beautiful... An Albatross on the wing warms my heart.
