Hi Clint. Thanks for prefacing your explanation of dynamic soaring with something to the effect of "I'm not sure," but you might want to consider reaching out to people who would know (e.g. university professors) prior to releasing an explanation. You had some correct elements and some not-so-correct elements in the explanation. Also, the difference in distance between the top and bottom of an airfoil is one of the standard myths / mis-explanations for where lift comes from. To establish a bit of credibility, I've been working as an aerospace engineer for almost 10 years now. I'm mostly doing motor control these days, but I got my masters from the University of Colorado at Boulder doing computational fluid dynamics in the aerospace department. I'm not an expert on dynamic soaring, but I'm familiar with the basics and governing equations. Because I can't draw fancy diagrams in the KZbin comments, consider a simplified scenario where the bird is flying into the screen at vx = +V with lateral winds of vy = +V_wind above the origin and vy = -V_wind below the origin. I'll try my best at ASCII art: x ---> V_wind × ----->y | > V_wind) which will create a large lift vector that will accelerate it in the direction of the wind. After a while, let's say that it reaches a lateral velocity of vy = +V_wind, i.e. it is moving right with the same speed as the wind such that there's no additional angle of attack or lift. If the bird then rolls to -90° and drop down below the origin where air is moving to the left, it will suddenly experience an extra angle of attack of 2V_wind/V and accelerate rapidly to the left until it is traveling at the same speed as that air. If it then trades a bit of kinetic energy to climb back above the origin where the air is moving to the right and rolls to +90°, it will once again experience an angle of attack of 2V_wind/V and accelerate to the right. This sets up a series of forces that push the bird around in a closed loop (well, helical-ish pattern since it's also still moving forward at velocity V). To overcome drag and keep V roughly constant, recall that lift acts perpendicular to the wind. However, the relative wind is not directly along the x-axis. Instead, it is angled "down" relative to the bird equal to the extra angle of attack seen by the bird. That is, 2V_wind/V when it first crosses the shear layer, decreasing to 0 as the bird accelerates to the same lateral speed as the wind. That angle also means that the lift vector is tilted forward in the same way that the lift vector was tilted forward in your kestrel example. If the tilt is large enough and the lift vector big enough, the component of the lift vector along the +x-axis will average out to the average drag experienced during the maneuver and the cycle can continue indefinitely with no energy injected by the bird. Instead, the energy is coming from the bird's lift vector slowing whatever air it happens to be acting on towards 0 speed. There's also an alternate and equally valid explanation based off of energy. The lift vector acts perpendicular to the direction of relative wind. If you define a coordinate system that is traveling with a body of air such that there is no wind, then the lift vector is perpendicular to the direction of motion and contributes no energy gain or loss to the bird IN THAT COORDINATE SYSTEM. In the above example, the bird would be traveling forward with a velocity vector of (V, 0, 0) prior to crossing the shear layer. However, after crossing the shear layer, it would have a velocity vector of (V, ±2V_wind/V, 0) relative to the new local wind-fixed coordinate frame. As long as it stays in a region where the wind velocity is 0 relative to this new coordinate system, it can use its lift vector to losslessly (neglecting induced drag) rotate the velocity vector wherever it wants (e.g. forward to create a new relative velocity vector of (√(V^2 + 4V_wind²/V²), 0, 0)). Transitioning to the other side of the shear layer causes the process to repeat. Your doorstop analogy is not relevant / wrong. In general, the bird will always be moving forward with a roughly constant airspeed of V. Any increases in drag will just require the lift vector to be bigger and/or to tilt forward more.

Keep in mind the oldest fossils of "false penguins" (genus Waimanu) come from the very early tertiary period at around 62 million years ago. No idea how old the auk lineage is, but this discovery alone puts the time where "false penguins" split off from other tube noses at some time in the cretaceous. Again. No idea about the history of the auks or their relatives but I wouldn't be surprised if it came to light eventually that the "false penguins" did it first. 😅 Edit: the reason why I'm saying all this is the earliest fossil 'false penguins' (i.e. spheniscids) we have looked recognizable as themselves, members of that lineage, so they would have been doing the penguin thing we are familiar with at that time already, distinctly different from other sea birds.

Penguins are not only extinct, they have one of the saddest extinction stories ever! Even more tragic than the Dodo or the American passenger pigeon (which went from multiple billions to extinct in like fifty years). Here's an example of part of the extinction story for the Great auk from wikipedia: "On the islet of Stac an Armin, St. Kilda, Scotland, in July 1840, the last great auk seen in Britain was caught and killed. Three men from St. Kilda caught a single "garefowl", noticing its little wings and the large white spot on its head. They tied it up and kept it alive for three days, until a large storm arose. Believing that the bird was a witch and was causing the storm, they then killed it by beating it with a stick." And this is what happened to the last breeding couple known to exist: "The last colony of great auks lived on Geirfuglasker (the "Great Auk Rock") off Iceland. This islet was a volcanic rock surrounded by cliffs that made it inaccessible to humans, but in 1830, the islet submerged after a volcanic eruption, and the birds moved to the nearby island of Eldey, which was accessible from a single side. When the colony initially was discovered in 1835, nearly fifty birds were present. Museums, desiring the skins of the great auk for preservation and display, quickly began collecting birds from the colony. The last pair, found incubating an egg, was killed there on 3 June 1844, on request from a merchant who wanted specimens, with Jón Brandsson and Sigurður Ísleifsson strangling the adults and Ketill Ketilsson smashing the egg with his boot." And there is even the personal account of Sigurður, who described how he strangled the last one.

[@johnathanmartin1504]

[@dsbromeister1546]

Hey Clint! Aerospace engineer here, about to be a pedant about your explanation of airfoils. Bernoulli's Principle only applies when there is no friction or inertia within the fluid, i.e., the air has no viscosity. That assumption actually makes it impossible for an airfoil to generate lift, because a perfectly inviscid fluid will always wrap completely around the airfoil, even the sharp trailing edge, such that a pressure differential never forms. Airfoils actually generate lift specifically because real fluids are viscous and, instead of wrapping around the trailing edge, curve to follow the chord of the wing, creating a vortex that ultimately induces an upward force on the wing. Now I usually deal with the "space" side rather than the "aero" side of my field, so I don't have a ready explanation for how the kestrel was able to hover in place, but your differential drag explanation for dynamic soaring makes sense to me. Either that, or birds have really powerful farts.

[@Sarcasticron]

What a great explanation, thank you!

[@dranorter]

There's a cool post by mathematician Terence Tao that I think matches well with the albatross' behavior. Just search "Terence Tao sailing against the wind faster than the wind". The albatross is using the lower-altitude air the same way Tao suggests using the water, IE, putting the airfoil into it only half the time.

[@mandowarrior123]

In both sailing and aircraft I recommend to treat them as deflecting surfaces and vector exchange. Up until a stall that's what they do. And vectors help you understand how you can travel much faster than wind with wind power alone. Essentially you fly perpendicular to the wind, using their minimal side drag and turning as much of that force into perpendicular motion, keeping the relative wind speed as high as possible. Hence it can fly up to 80 mph 'for free' It's a little similar to a solar sail if you're into that kind of thing, or gravity assists. It slows the wind down in exchange for its energy, if you'd like to work it backwards.

[@NelsonBrown]

Like the parents at the zoo when the kid asks if this bird is more related to a gull or a (false) penguin, it would be better for Clint to say "I don't understand dynamic soaring." Also, that's not how aerospace engineers say "Pitot" - Henri Pitot was French.

[@twobladedswordsandmauls2120]

To answer your question about Albatrosses (in an over simplfied manner because this is quite literally rocket science): While wind speed increases at higher altitude, the actual energy of the wind doesn't change. The cost of the higher speed is lower inertia, which allows the energy to be transferred far more easily. As the Albatross gains altitude the wind pushes on it more. While this causes it to lose velocity, it also gains lift. This pushes the albatross higher into even faster moving air. Eventually, the energy gained from lift starts to become not greater then the energy lost due to drag, and the Albatross tilts its wings and dives. This turns the potential energy it gained from the wind pushing it into the air into kinetic energy, which is more than enough to overcome the drag of the lower velocity, higher inertia wind closer to the ocean that is far worse at transferring its energy to the albatross to slow it down. Eventually, the drag costs the Albatross enough velocity that it begins the loop again, allowing it to maintain essentially the same amount of energy that it started out with. The Albatross also has a similar method (that is even more efficient) for flying cross wind, and of course doesn't need any particular help for flying with a tailwind. So the only real problem comes from flying with no wind at all, but that doesn't really happen on the ocean. While Doldrums are a thing, they exist because the heat of the sun is causing the air to move rapidly vertically, which is not nearly as much of an issue for an Albatross as it is for a sail boat.

[@FireMageTheSorcerer]

So it's a bit like going down a slide and climbing up the ladder again?

[@MrPestkranker]

​@@FireMageTheSorcerer Yes, pretty much. The climb up just costs as much energy as sliding down

[@mollydelacy9007]

I just think about how airplanes stay aloft. I feel like it very similar in that for a plane that's already flying but losing altitude, it first needs to go nose down, to receive more inertia in order to go back up or to receive lift, which slows a plane down. Then its able to maintain and ride on the air current like a glider works the same way as well. Hot air↓→Cold air↑→around and around it goes.

[@orppranator5230]

So it’s like a wind turbine collecting energy against a faster headwind with less density at higher altitudes, and then spending that energy against a slower headwind with less density at lower altitudes?

[@dexter7954]

Hey Clint I'm a student of aerospace engineering and the dynamic soaring bit is something I understand pretty well. I've taken a few days to figure out how to explain it: First I'd like to picture this in forms of energy - Kinetic Energy and Gravitational Potential Energy. Now picture the airflow at high altitude an "infinite" well of high velocity, high energy air. High Speed = High kinetic energy, High altitude = High potential energy. Albatrosses take kinetic energy from this "well" of high energy air, use it to kick their speed up. Once they match the velocity of the airflow, they dip down, trading their high potential energy for even more kinetic energy when dipping down to low altitude low energy air. They use this high velocity to generate lift over their wings, to kick back up into the high altitude high energy air. By the time they reach high altitude again, they have traded their kinetic energy for potential energy, losing their speed. Due to the high energy air at this altitude they can once again tap into this energy well and speed up again to repeat the cycle. Hope this helps you better understand this!

[@DJFracus]

Well it would be easy to assume that the wind pushing you downwind is canceled out by the the wind pushing against you headwind. Only reason this isn't the case is differences in how aerodynamic the bird is from the front and the back.

[@KAZVorpal]

Clint, my friend, your interpretation of why that kestrel can hover in place is CLOSE, but does not quite earn the tobacco-leaf implement of phallicity. Please consider this: 1. As the bird's wing generates lift from the wind, especially because it's cambered instead of flat-bottomed or symmetric (kudos for the graphic mentioning cambered airfoils), it generates slightly TOO MUCH lift, so that the bird should rise. 2. The bird therefore "dives" slightly, bleeding off that extra upward energy. 3. That "dive" converts the extra lift into FORWARD thrust, enough to hold it in place. This is why it's not a perpetual motion falconid: It is generating forward thrust by "diving" to remain level, when the wind is generating too much lift and it should rise. But IT IS NOT BERNOULLI. Well, not primarily. Falconids like kestrels hovering are taking advantage primarily of lift generated by Newton's Third Law, NOT the Bernoulli principle. The kestrel's wing generates lift more because the airflow around its cambered wing pushes air downward than because of air-pressure lift via Bernoulli, which contributes but is far less powerful. The coanda effect is part of this Newtonian thrust, pulling air downward on the trailing edge of the upper and lower surfaces, so that the air comes off the back of the wing with downward momentum. Think of it as being like a rocket or jet, the downward flow of air creating an equal and opposite upward thrust on the bird's wing. a. Bernoulli's Principle is the most intuitive explanation for the main source of lift for the Wright flyer/biplanes. b. Newton's Third is the dominant force for procellariiformes like Albatross, and falconidae like kestrels, and is completely different from Bernoulli, though that's a minor player in this situation. c. Kutta-Joukowski Theorem best describes lift in modern, highs-speed jet aircraft. It's a formulation of lift via circulation around the wing, rather than pressure-differential calculations. post scriptum: That not-American-kestrel video you shows harkens back to your other video on pigeons, and why their heads bob. The kestrel is holding his head perfectly still - like a chicken being waved around by a farmer. Pretty awesome. I wish you'd mentioned that explicitly (like when you called out your paleognathae video), it ties together perfectly.

And if you’re a French-speaker, the bird at 0:58 (the Razorbill) is a true penguin (meaning that not only are penguins not extinct after all, but all the living ones can fly!), but the spheniscids still definitely aren’t; they are “manchots” (meaning “one-armed”, probably for the same reason the extinct auk was named Pinguinus impennis, “penguin without feathers”!) Of course, given your stance on the pronunciation of “niche”, I expect you to stick to your guns about penguins consisting of just one now-extinct species. Though, would you perhaps be willing to consider the Razorbill (the Great Auk’s next of kin) the “hagfish of penguins”?

Retired physicist here. A comment on your explanation of dynamic soaring. First I'll explain dynamic soaring. It works by having different wind speeds at different heights. When facing a wind, that is facing air that is moving towards you, this is equivalent to moving into the air mass. In either case the difference in velocity can be used to generate height. It is the different in air speeds that supplies the energy. In doing so you would eventually move at the same speed as the air, and would no longer be able to generate lift. However if you get enough lift to get into the next layer of wind speed in which case once again you can use the difference between how fast you are going and the air to generate more lift. Again, eventually you reach the same speed as the air and no more lift is available and you drop. When you drop into the slower moving air you again use the speed differential to gain lift. In each case energy is transferred from the wind into the bird. The reason why this is not a perpetual motion model is that the difference in wind speeds is a form of useful energy. To compare to another example think of the situation of two moving walkways side by side but travelling in opposite directions at 1m/s, and where moving from one walkway to the other takes no energy. Starting on one walkway in a cart. Then move over to the other. You suddenly find yourself moving at 2m/s. This energy can be absorbed by your electric braking system to the tune of 1/2 mv2. and your cart then moves at the speed of the second walkway. You can then move your cart back to the first walkway and do the same and absorb energy to the tune of 1/2 mv2. And can keep doing this forever. This isn't energy for free. The energy that is being absorbed by the cart is being supplied by the walkways and without something powering the walkways they would eventually (or quickly) be moving at the same speed as each other. The principle is identical with the layers of air travelling at differing speeds, and the energy that the bird receives is from the difference in the wind speeds. Without the suns heating providing the energy to maintain the differing wind velocities, the birds action of going from one stream to the other would hasten the demise of the difference and eventually the wind speeds would be the same everywhere with the birds no longer able to extract any more energy. The example, as you described with the kestrel cannot happen due to conservation of energy. If the wind is constant and horizontal with no vertical component, then the kestrel can generate a lifting force, but it cannot generate energy to counter the energy lost in friction against the wind. The kestrel would have to start moving backwards with the wind. If what you claim were true then the kestrel could fly when there was no wind without using its wings in exactly the same manner merely by reaching the velocity required. The kestrel hovering into a wind of 20m/s is identical to a kestrel flying at 20m/s in still air. Ironically what you are describing is a perpetual motion machine.

[@conlon4332]

So how do kestrels hover?

[@chriswatson7965]

@@conlon4332 There is either an updraft or they are actively using their wings. I just had a look at one video and there was a clear stiff breeze going upwards and the kestrel was holding his wings as if it was falling.

[@jpe1]

@@conlon4332the wind is blowing strongly enough that the kestrel would climb (like a kite) if it were in “level” flight, but if you look closely you can see that it is, in fact, _diving_ slightly down toward the ground, and that downward pitch is converted to forward thrust, countering the drag force of the wind. No updrafts needed.

[@markallen6433]

This is a good explanation, but a bit difficult for some people to appreciate, I imagine. Might be easier for people to get a sense of dynamic soaring by saying something like this. Flying works by moving through the air, and using that movement to generate lift and maneuverability. When you have wind moving at two speeds, when you transition from one to the other in the right direction, you feel like you are going faster suddenly, and thus have more "airspeed" with which to generate lift and maneuver. I think if you start with that core concept, more people without engineering degrees will be able to grasp it

[@daemn42]

Regarding dynamic soaring. You're right, proper airfoils + gravity produce *thrust*. This is best understood with the L/D ratio aka "glide ratio". In wings level/pitch level flight it defines how many units of forward motion an airfoil moves to every unit of "down" (I'll explain why down isn't always down later). An airfoil with a 10:1 glide ratio moves 10ft forward for every 1ft drop. A Wandering Albatross has a glide ratio of about 21:1. The glide ratio is effectively telling you how much thrust an airfoil is producing with 1G of wing loading. If you "drop" the aircraft (including a bird) then it goes forward instead of down. Now here's the key to understanding dynamic soaring. The glide ratio (and the thrust it produces) applies whether you're gliding straight and level, or oriented vertically and turning hard. You always get much more "forward" than "down". The airfoil produces thrust when it is pulled perpendicular to its span (-Z axis), and doesn't care whether that pulling force is gravity, or because it's turning (G forces). It is not about just "changing direction" in headwinds and being "pushed" by tailwinds or storing energy in altitude. Please get rid of all that type of thinking. It is all about creating gains in instantaneous airspeed by crossing wind gradients then making *hard* turns and coasting. FWIW, my qualifications to talk about this topic are as a DS pilot who's piloted a 30lb sailplane to 407mph, who also hangs with those who regularly fly em into the mid 500's. I've flown tens of thousands of DS laps in the last 20 years. Let me explain RC dynamic soaring before the albatross. With RC DSing, we're looking for a relatively quick wind gradient (a wind shear) which is typically formed when wind comes over the top of a relatively sharp ridgeline. High above the ridge the wind is blowing hard one direction, and somewhere below that (not necessarily below the top of the ridge) is air that is close to still or even has a little return flow. We then pilot our aircraft in a roughly circular path with wings oriented perpendicular to the slope of the ground on the back of the ridge that takes us briefly into the strong wind above, and the still air below the wind shear. We gain velocity relative to the ground while turning hard above the shear line and coasting through the still air, losing less velocity than we've gained, until we reach our top speed (at which point the total gains and losses match). As a rule of thumb the glide ratio while turning hard can be used as a simple multiplier, roughly determining how much peak air speed we can gain for any given wind speed. In other words, if a sailplane has a 10:1 glide ratio while pulling a 10-20G turn then it will peak out around 100mph in a 10mph wind. To be clear, the energy we gain is not from "turning downwind". The wind is never pushing on the back of the airfoil. They always experience an apparent wind from the front (just like a sailboat on a reach). It comes from executing a high G turn following a rapid increase in airspeed while retaining a relatively high glide ratio. With this turn the increase in airspeed is converted into a higher ground velocity in a different direction. I say "retaining a glide ratio", because the glide ratio is not constant. It is highest at the lowest wing loading, and decreases as the wing loading increases which happens in a high G turn. So my sailplane could have a 20:1 glide ratio when flying level, but in a 10-20G turn it decreases to 10:1, but that's still enough to go 10x the speed of the wind.. There are birds like swifts which DS *exactly* the same way we do, above/behind ridges, roof tops, and around corners of buildings. They may do it in circles, or they may snake down the ridge (continous S turns instead of Os) for long distances. They can slope soar as well, but they are masters of DSing, and I've literally had them fly circles around me audibly whipping through the wind shear only feet away from where I'm standing while I'm piloting my sailplanes. Ok, now back to the albatross. They don't have a stationary pointy ridgeline, but they do still have a relatively fast changing wind gradient when they're flying over open ocean in big waves. The lowest level wind is what creates and powers the waves so the wind speed is lowest near the waves (having expended its energy there), and blowing fastest up higher. The albatross does not climb to store energy. Quite the opposite. It climbs only to get to get into the higher speed wind, and then just like our RC sailplanes it puts its wings up near vertically (perpendicular to the surface) and briefly *pulls hard* perpendicular to the wind itself. Given its high glide ratio, it gains a burst of forward velocity (relative to the ground) from pulling hard *across* the wind, and then it dives (it gains little if any speed from the dive itself. It's just a means to re-cross the wind shear) down into the low wind speed region, and coasts in literally any direction it wants (including straight upwind) for a relatively long time slowly losing airspeed. It periodically uses it's last remaining kinetic energy after coasting to pull up into the higher speed wind, pull hard across the wind, rinse repeat. This is why almost every photo of an albatross flying has its wings oriented 45-90 degrees instead of horizontally like most other birds. They're most visible when they're in their power phase turning across the strongest wind up high, and then they often disappear down low between the waves. They also utilize the ground effect (flying anywhere below 1/2 span from the surface) to increase their gliding efficiency. TL;DR: There are a lot more subtleties to DSing in all its various forms, but fundamentally it is about utilizing a relatively high glide ratio wing to execute high-G turns *across* the wind (not necessarily from upwind to downwind) while repeatedly moving back and forth across a wind shear so you can retain the gained ground speed to either make distance or recross the shear to get back into the powerful wind to go faster.

[@agavolm4826]

I have another example for the Albatross hovering! As I gained more experience from biking, one technique I found useful for up long, gentle slopes (going against very acute angles) was to sway up and down a crooked surface. What I mean by 'crooked' is a surface that has a visible angle/tilt to any part, be it a cracked settling area, or a natural/intentional bend. When you bike along a gradual upward angle, it can really slow you down without even noticing, causing you to work way harder to fight this type of resistance. But the technique of waying between uneven angles will actually aid your muscles by getting back a little more efficency of speed per pump. The best places to take advantage of this gain along sidewalks are the divides between streets; they have both a change in angle (some more than others), and they are longer in length, even longer when the street compliments the curbs alongside it. For streets and roads, the best place will (obviously) be a runoff curb (the gentle sloped curb, instead of the jutting tire-stoppers); most roads, especially those near flood zones, need a way to keep water from pooling on the pavement - causing things like ice, extra erosion, potholes, and warping - and instead going to the storm drains or ditches. The solution is to curve the surface sightly, allowing gravity to work its' magic! Riding between the smoother curbs and the curve of the roadside will add an extra boost with each sway, basically creating a snaking acceleration panel like you video games!! I think that sums that example well. Let me know how viable that is for a comparitive explaination of the Albatross flightplan.

Private pilot here - there is a thing called ground effect, depending on size & surface area of the flying object, the air is compressed between ground/water surface & the wing, making the air denser & providing more lift.
