Why don't you get to think of a suggestion and creating a TH-cam Videos all about the Bizarre Bird Species called a Shoebill (Balaeniceps rex) 👞 🐦 on the next Bizarre Beasts maybe next month in June coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
I have a serious question for people using a thing like this, is it because you can't sleep due to lights/sounds etc? I used to live a somewhat rough life early on so I got used to sleeping with sounds and lights(along with sun) without any issues. I always thought this was normal until I heard that a lot of people are struggling which came as a surprise to me. Makes me wonder how long it took to adapt to in the first place. To be completely honest I do need some sort of sound going on to be able to sleep so that's the downside I have a hard time sleeping in complete silence but that isn't an issue when you're living in a big city.
I already have the Manta Sleep Mask Pro from a different sponsored video and use it every day at work to take naps on my 15-minute breaks. I work in a warehouse, but finding a spot to snooze in is pretty simple. Just need three tall totes: 1 as a seat and the other 2 stacked very strategically like a table. The mask is cool cause the eye cups are modular and can be pulled off and reoriented on the mask itself due to velcro. The cups also don't put pressure on your actual eyeballs like generic sleep masks do since they're cup shaped rather than flat.
In the future, we will either create mutually beneficial relationships with all of these people and animals whom we haven't yet met (such as these rails) which will be worth defending, or we will be guilty of being "Against" these harmonious relationships. Some things never become less modern. People who love their job and wouldn't mind being left alone have freedom and are subject to their own intrapersonal "judgement" regarding any mistakes which they've made while "under oath". This is what guides people toward success. Some of us have no identity, nor oath. It seems like the oath is like a fountain from which identity is granted. So our focus on safety is superfluous, but success/progress are NOT. What if we were trying to MORE than simply get things "back to normal"? Do you want things to be Better Than Normal for the first time? What's the Oath for that? What's the identity of people who want things to be Better than normal? Do they not have identities yet? We don't yet have a "Steve Irwin-ist" era of journalism where "history is defined by the victor".

Thank you for not falling down the aforementioned media rabbit hole of “this bird evolved twice” and instead establishing the probable distinction between the two iterations. And regardless, this was a very interesting video, as per usual!
Fun fact! Their use in railroads led to breeding programs and an explosion in their populations, but it was ultimately the coming of cars and paved roads that led to their decline
What an odd poetry that the thing we think of as "the most bird-like" thing about birds - their flight - is something they "seem to hate doing" since it's so energy intensive, and is one of the first things they ditch given half a chance and no penalties for doing so.
Probably even more difficult for flying foxes who may not be as well adapted for flight as birds and have to carry baby around with them in the case of the females.
Then there’s chickens all the advantage of ground birds while retaining the ability to fly really well if needed all while having a lot of predators. Now there’s more of them than humans and they’re smart enough to be our successor species if corvids don’t get there first
That would be pretty wonderful. All the stinky plants, exploding plants, plants that just ALWAYS choose violence, plants that will both sting you AND can be used to soothe the sting they just made, plants that give you sun sensitivity for extended periods of time...
If I had a nickle for every time a flightless aldabra rail evolved on the Aldabra atoll I'd have two nickles. Which isn't a lot, but it's weird that it happened twice, right?
Oh, I am an equal opportunity lover of fluffy chicklets 😂 we are birb folks over here. I agree about the color difference, all black growing into more colorful is somewhat unusual.
My favorite name for a flightless rail is an Atlantic species, the Inaccessible Island Rail. Named for its home island, which is not so much hard to get to as hard to set foot on.
Behaviorally they really remind me of chickens. Chickens do the same things. I have one who always tried to eat the little brown mole on my leg. It's like they get fixated on an image and decide "i'ma try to eat that"
@@mattfleming86 They think it is something like a tick or maybe something that is stuck on you like part of plant you brushed up against or dead skin as many species of birds will clean other animals of things like ticks or build up of dead skin and plant material. Same thing is happening in the video the bird sees something like a small bug or dead skin and wants to eat it. Even birds like crows will do this when it comes to ticks which shows just how common the behavior is.
@@greywolf7577 I feel like every day he starts a new channel that I then tell TH-cam to block, only for me to get recommended a new video from him on another channel the next day.
Bizarre beast suggestion: Nothobranchius killifish Shortest lifecycle of a vertebrate species. Nothobranchius Fuzeri mature, spawn, and die within three months. They lay there eggs in mud that dries out for months until rain comes again. Bonus: they're super colorful and cool looking!
OMG YES killifish are so cool! I have a species of longer living ones and its interesting how their eggs have a far longer incubation period then most fish of that size. I guess that is because their ancestors where seasonal fish that readapted to a "normal" livecycle. I don't know if this is actually the case for this genus (Epiplatys), but i heard that there is genetic evidence in some killifish, that they have switched between stategies multiple times in the past, which is just evolution at it's finest.
It seems to me that this is just convergent evolution, but happening at different times. Rather than two species of far different classifications evolving into similar forms, it's two species of far different times evolving into similar forms.
Your wording is incorrect by not presenting valid comparisons, but that aside, one point; convergence doesn't require the taxa to be contemporaneous, so that part is irrelevant.
So basically, it's a case of convergent evolution with a common ancestor. A evolved into B, and then later A evolved into C; B and C just happen to have similar traits because they evolved under similar (basically identical) conditions and started from the same form. Neat!
Wow, those rails have deep and enduring beef with crabs, I'll bet the crabs have a tendency to predate rail eggs and young chicks. Or they just don't like the look of ocean bugs? 🤔
A scientist may also have to take into account how the environment on the island may have changed over time from how it used to be before the flood/severe storm, then how it may have changed after the water receded.
please do an episode on the Aldabra tortoise the second largest tortoise in the world and they are endangered. And you can get one from a reputable breeder causeway they are being bred commercially be aware they are the second largest tortoise they can weigh up to 500 lbs. And they're very very friendly.

Aldabra tortoises are vulnerable (just one step from endangered) according to Wikipedia and PBS and IUCN. So @shaden0040's comment was incorrect, but there is indeed concern about the species.

Awwww... those little black fluffybutt Rails are adorable! 🖤🖤 And this is (as Hank mentioned) like how things like to become crabs, except in birds, so it's not really so surprising, IMO. Interesting, yes - very! But not horribly strange. 😊
The book "Improbable Destinies" is about this feature of evolution. It covers evolutionary experiments with introducing lizards to tiny islands in the Caribbean and allowing tiny fish to colonize pools upstream.
You are right! Dodo's are related to pigeons! We were just saying that they are the most famous flightless bird that lived on an island in the Indian Ocean, not that they were also rails.
When you're a paleontologist and someone says "Matrix": "Ah, the sediment or rock that encloses a fossil. Fascinating!" When you're a movie fan and someone says "Matrix": "Red pill or blue pill? Welcome to the real world, Neo!"
I really hate it when people make assumptions like "they are flightless bird therefore they went extinct". One thing I know about birds is they are very light and therefore can float very well on water. Their are bird that can swim in water, not just pinguins. Who's to say they didn't just traverse the ocean blue to another Island/atoll? Who's to say that they didn't do this even before the island was underwater? Who's to say they didn't find another way to survive? The only way to know for sure would be genetics. Since all we have from before the island/atoll flooded are fossils, no DNA can be found. Nature can find ways to do the impossible.
Penguins are flightless birds but water is a second home to them, many birds like seagulls can float, so the question is, did those rials go extinct when the island flooded? Or did some of them float to another island somewhere and return later after some evolutionary tweaking.
Species translates to something like “semblance/form.” When the word was first used by scientists they meant “these all have the exact same form and do the exact same thing.”
Unaddressed question, can the flightless Aldabran rails still mate successfully with the Madagascan root stock? are they separate species or sub-spieces? if the flightlessness evolved in 16,000 years from the same root stock and they can still successfully breed with their root stock it is conceivable that the pre-flood sub-species could breed successfully with their post flood cousins.
The thing that gets me, if that bird evolved on that atoll that could have been swallowed up by waves... What obscene ungodly impossible level of probability had to happen for that atoll to not get swallowed up by waves for the millions of years needed?
In New Zealand we have 2 that are flightless and another 2 that are/were getting that way.... .....before the greatest selection pressure of all time showed up that is.
Iterative evolution is kind of amazing because it shows how strong selective pressures and strict niches can generate the "same" species multiple times.
How do we tell the difference between rail evolution and rail manifestation of ancestral flightless trait manifesting in the presence of their ground-foraging, low-predator island lifestyle? Are there species of birds that have adapted from flightless to flight, and back again, the way some animals have gone from aquatic to land back to aquatic?
They also only have a limited number of survivable mutations in their DNA so under smaller conditions, the same mutations will provide similar evolutionary advantages and thus phenotypically the appear surprisingly similar.
What I found interesting was in the scenes where you see the bird pecking at a relatively large crab, I noticed that it was a female crab carrying eggs and the bird isn't so much pecking at the crab as much as it is stealing the crabs eggs. That is one way to keep the land crab population under control.
@ I would prefer they continue their excellent content than answer all of our stupid comments. Games, what a stupid thing to waste one’s time on. Really? Wise up!
Similar to the Eastern Coyote, a newcomer to the Eastern US and a recent wolf-coyote hybrid, which has filled the niche of the nearly extinct Red Wolf, which was probably also a wolf-coyote hybrid from tens of thousands of years ago.
Is the rail going after the crab, or the eggs it's carrying on it's underside? It looked to me like they were just trying to pluck off a few eggs, not take out the entire crabby boi.
The forelimbs of bird like dinosaurs seem remarkably prone to mutation. In this case, does the bird have a variant floating around the gene pool just waiting for a chance to express itself?
I would hope that certain birds like that would develop the ability to at least float on top if the water. A lot like how Ducks do.. Obviously they won't have the waterproofing effect that most birds that evolved to interact with water have developed
Right? I would've just stayed home (Madagascar), flying all the way to Aldabra seems like such a chore. And now there are humans, to make matters worse
if it looks like a duck, walks like a duck, sounds like a duck, smells like a duck, eats like a duck, raises young like a duck, exhibits all the exact same behaviors as a duck, evolved from the same older bird as a duck, is indistinguishable from a duck even under close scrutiny and under many microscopes, it might not be a duck, because one protein in it's RNA sequence is slightly different. yeah that tracks logically.
A pair of identical twins fit that definition yet clearly aren’t the same person. These birds are a case of convergent evolution, just at 2 different points in time. There’s no reason to think that they would even be genetically similar either because it’s likely that the founder population in both cases had some differences. They literally can’t be considered the same species because the birds there today are not descended from the ones that used to live there.
So this isnt two identical evolutions of the same parent species, but this _near_ identical evolution of the same parent species raises an interesting evolutionary possibility: could iterative evolution be a factor in the development of traits that are reinserted into the parent population? Say theres an island that is periodically connected to the mainland when sea levels drop where flightless birds evolve during periods of isolation, that are then reintroduced to their flying relatives when the island becomes connected again. The level of speciation isnt so radical that the two populations can't interbreed, so the flightless gene is taken up by the flying population. This process repeats many times until enough copies of the flightless gene get introduced to the flying population that it primes the flying population to evolve flightlessness at the drop of a hat. Or something similar. I was actually thinking about hammerhead sharks, but i dont think there's any evidence that they went through iterative evolution.
Dragsters are called "rails"... You can "rail" at someone in anger... you can have a Stair rail... you can have a chair rail... and of course a train rail... I'm sure there are many others I don't know of... 🤔
Coral atolls form at the top of seamounts, many of which are extinct volcanoes. Extinct volcanoes inevitably collapse, resulting in gradual subsidence and causing what was once an island paradise to sink beneath the waves. No sea level rises necessary. It just is what it is. That said, the ups and downs of sea level adds it's own consequences to this and, what can I say? It's never easy!

Unaddressed question, can the flightless Aldabran rails still mate successfully with the Madagascan root stock? are they separate species or sub-spieces? if the flightlessness evolved in 16,000 years from the same root stock and they can still successfully breed with their root stock it is conceivable that the pre-flood sub-species could breed successfully with their post flood cousins.
The thing that gets me, if that bird evolved on that atoll that could have been swallowed up by waves... What obscene ungodly impossible level of probability had to happen for that atoll to not get swallowed up by waves for the millions of years needed?
Please upload more rail vs crab footage!!!!
I noticed that Hank carefully avoided mentioning the third rail.
In New Zealand we have 2 that are flightless and another 2 that are/were getting that way.... .....before the greatest selection pressure of all time showed up that is.
Thanos: I am inevitable.
Some atoll bird: 🐦
Was “that we know of” a reference to Lindsay Nikole 😂😂
Iterative evolution is kind of amazing because it shows how strong selective pressures and strict niches can generate the "same" species multiple times.
How do we tell the difference between rail evolution and rail manifestation of ancestral flightless trait manifesting in the presence of their ground-foraging, low-predator island lifestyle? Are there species of birds that have adapted from flightless to flight, and back again, the way some animals have gone from aquatic to land back to aquatic?
Cetaceans and sirenians are both fully, secondarily aquatic.
Question: do the rail birds eat the crabs? Or are they pecking at the crabs because they are annoyed?
I was wondering the same thing. The crabs look too big for the rails to eat, though.
This seems like Zelda games lore shenanigans
Hank your new hair looks so great! I hope you think so as well. Keep up the awesome.
They also only have a limited number of survivable mutations in their DNA so under smaller conditions, the same mutations will provide similar evolutionary advantages and thus phenotypically the appear surprisingly similar.
What I found interesting was in the scenes where you see the bird pecking at a relatively large crab, I noticed that it was a female crab carrying eggs and the bird isn't so much pecking at the crab as much as it is stealing the crabs eggs. That is one way to keep the land crab population under control.
Thanks!
Don't waste your money here
Spend them on a multiplayer game like Moba games poke unite,League of legends etc.these people don't even give you a reply
@ I would prefer they continue their excellent content than answer all of our stupid comments.
Games, what a stupid thing to waste one’s time on. Really? Wise up!
Bird versus crab. A rivalry as old as time.
This tactic might work on the dodo next year
This makes me think something almost like a human could have access to somewhere in deep time maybe even before the dinosaur.
Similar to the Eastern Coyote, a newcomer to the Eastern US and a recent wolf-coyote hybrid, which has filled the niche of the nearly extinct Red Wolf, which was probably also a wolf-coyote hybrid from tens of thousands of years ago.
The eastern coyote also tends to have a percentage of domestic dog mixed in with the wolf DNA.
Is the rail going after the crab, or the eggs it's carrying on it's underside? It looked to me like they were just trying to pluck off a few eggs, not take out the entire crabby boi.
The forelimbs of bird like dinosaurs seem remarkably prone to mutation. In this case, does the bird have a variant floating around the gene pool just waiting for a chance to express itself?
This has real "Nature loaded up a save file" vibes.
I would hope that certain birds like that would develop the ability to at least float on top if the water. A lot like how Ducks do.. Obviously they won't have the waterproofing effect that most birds that evolved to interact with water have developed
Man, life isn't hard enough the firs time 'round?
Right? I would've just stayed home (Madagascar), flying all the way to Aldabra seems like such a chore. And now there are humans, to make matters worse
if it looks like a duck, walks like a duck, sounds like a duck, smells like a duck, eats like a duck, raises young like a duck, exhibits all the exact same behaviors as a duck, evolved from the same older bird as a duck, is indistinguishable from a duck even under close scrutiny and under many microscopes, it might not be a duck, because one protein in it's RNA sequence is slightly different.
yeah that tracks logically.
A pair of identical twins fit that definition yet clearly aren’t the same person. These birds are a case of convergent evolution, just at 2 different points in time. There’s no reason to think that they would even be genetically similar either because it’s likely that the founder population in both cases had some differences. They literally can’t be considered the same species because the birds there today are not descended from the ones that used to live there.
Just reading about the Inaccessible Island Rail on Wikipedia and had to come back to this.
Evolution never ends!
So this isnt two identical evolutions of the same parent species, but this _near_ identical evolution of the same parent species raises an interesting evolutionary possibility: could iterative evolution be a factor in the development of traits that are reinserted into the parent population?
Say theres an island that is periodically connected to the mainland when sea levels drop where flightless birds evolve during periods of isolation, that are then reintroduced to their flying relatives when the island becomes connected again. The level of speciation isnt so radical that the two populations can't interbreed, so the flightless gene is taken up by the flying population. This process repeats many times until enough copies of the flightless gene get introduced to the flying population that it primes the flying population to evolve flightlessness at the drop of a hat.
Or something similar. I was actually thinking about hammerhead sharks, but i dont think there's any evidence that they went through iterative evolution.
This birb always comes back
North American rails are so secretive and hang out deep in swamps, it's such a thrill when you get to see one!
Dragsters are called "rails"... You can "rail" at someone in anger... you can have a Stair rail... you can have a chair rail... and of course a train rail... I'm sure there are many others I don't know of... 🤔
I wonder if its possible to recreate a dodo bird if we force a similar species to go reiterative evolution
Coral atolls form at the top of seamounts, many of which are extinct volcanoes. Extinct volcanoes inevitably collapse, resulting in gradual subsidence and causing what was once an island paradise to sink beneath the waves. No sea level rises necessary. It just is what it is. That said, the ups and downs of sea level adds it's own consequences to this and, what can I say? It's never easy!
I love Hank's chemo curls 😅
What if some of them were just holding their breath until the island came back?
a correction, dodo is a pigeon relative not a rail.
07:20 RÉUNION MENTIONNED RAAAAHHH 🗣️🗣️🗣️🇷🇪🇷🇪🇷🇪🇷🇪
Omg they’re just little guys
some evolve to become crabs and some become... barnacles. yeah, they are the same freaking family
Flight is a disadvantage...until it's a huge advantage.
Interesting, but when the atoll sank what says the birds, tho flightless, didn't just swim to other atolls?
They don't evolve twice. They were just island boys...
Good video
💙
Weren't kidding about them curls! Good job though.
