The Time When Dinosaurs Rose Again - Terror Birds
The dinosaurs as most people know them, in other words, non-avian dinosaurs are gone, but dinosaurs are still very much alive, through birds. Admittedly, these guys don't quite live up to the reputation as some of their ancestors, but not long after the demise of the non-avian dinosaurs, there was a family of birds that emerged that came pretty darn close to becoming just as scary as some of the fiercest dinosaurs, these were the terror birds.

A chicken pecked my finger this summer, it hurt, it was at that moment I realized I had just been attacked by a dinosaur and survived, a feat not many people can attest to.
Did you make dinosaur shaped nuggets out of it in revenge?
@@posticusmaximus1739 No, but I thought about it. Dinosaur meat, e.g. chicken nuggets, taste good!
Ironically...the chicken is the closest relative to the T-Rex.
@@IspeakthetruthifyAll birds are equally closely related to the T. rex. The whole chicken/rex thing is just a factoid that gets overshared to the point of establishing itself as common “knowledge” despite its inaccuracy.
You may be surprised how many people get attacked by chickens, geese, swans, etc.
Imagine coming across one of these terror birds and how scary it might be.
Better wear a helmet.
Couple of years back I was fishing and started walking back home through a forest and heard heavy footsteps and like 4 emus ran by scared the hell out of me lol reminded me of raptors from Jurassic park turns out the emus had escaped from a farm
That requires a LOT of french fries !
Whenever I see a bird I just picture it as a hot steaming rotisserie chicken fresh for the eating, with garnish and those little white things on its legs like in the cartoons.
My ex bird was a fucking lunatic.
It's crazy to think that dinosuars actually survived, just a small group of them. And we eat a lot of them.
Kentucky fried dinosaur
Tables have turned. Mammals used to cower at the feet of therapods, living in fear of being consumed by them. Now it is us mammals, who consume the therapods... in bulk!
Crazy thing is birds account for the highest diversity in vertebrae animals
Yeah don’t think about it too much
it was like that then it swapped and it us again... im scared of the chickens hatching up a plan@@posticusmaximus1739
I live in a farm and own chickens and turkeys. For every farmer who is interested in dinosaurs and owns these lovely birds, when you see them move and communicate, I can sometime imagine how the dinosaurs really sounded like. If you don't believe me, try to record the sound when chickens really screams and magnify that sound, you'll hear the voice of the great dinosaurs.
The first time you hear a rooster roar while sitting on the ground next to him, you definitely feel the dino vibes.
Seagulls do it for me. Goddamn raptors, both in appearance and attitude.
Chickens are crazy animals indeed!
My family had chickens and I remember when I saw their legs and then I thought about what I had been told about birds being the last of the dinosaurs and I could see it was true.
A 400kg predatory bird must have been a sight to behold. Man, I wish this group were still around.
Not me 😮
Yeah, gonna pass on the refrigerator sized Canadian goose.

The Phorusrhachids are my personal favorite extinct bird lineage. They were basically birds that reminded you that they are Therapod dinosaurs
props to terror birds basically becoming dinosaurs again even after the furry critters took over
They were never not though
Mammals didn't take over until after the thermal maximum roughly 30 million years ago. It's a common misconception that Mammals took over right after the dinosaurs went extinct. Cold blooded reptiles ruled the planet after the extinction of the dinosaurs because they were in the best position after the extinction. Avian dinosaurs and mammals took a long time to recover post extinction. Both groups suffered alot more than people think during the extinction.
pretty sure he was saying terra, not terror.

@@egay86292 How could I forget
It should be noted that pretty much all the large terror birds were animals of forested habitats rather than open terrain and functioned as ambush predators (albeit ones that could also pursue prey for longer distances) of larger herbivores. They were still reasonably fast, but that in itself doesn’t make them pursuit predators
They were not forest habitants. They lived on savanna and plain. The very last species titanis was found in Texas and there are no forests in texas.
@@chrisdonish They were forest animals, and all the larger ones lived in areas that were forested *when they were around.* Titanis wasn’t only found in Texas, and the loss of forest cover IS WHY IT WENT EXTINCT.
@@bkjeong4302 Huh... So ironically one of the only pop culture media that got it right, was _10 000 B.C._
@@freshboy3968 I mean that movie it'ss a banger so it checks out
I find it interesting that the skull geometry of the biggest terror birds is very similar to T-Rex. There is a noticeable curve in the mandible in both animals. Somewhat similar to pruning shears. I’m guessing the physics of that curve in conjunction with a taller skull, or in the case of the bird, a beak, allowed them to deliver fantastic bite forces. The taller skull I would also presume allowed for larger jaw musculature, and therefore more power.
Thank you for using relevant photos. I've noticed more and more that some info channels getting lazy with their photo presentation, and using misleading photos without mentioning that the photos aren't actually of the topic being presented.
I know I have said this many times, but I desperately want a documentary about South America from the Paleocene to Miocene ever since there where so many fantastic creatures that inhabited the continent during its millions of years of isolation. I also thought about having a narrator of Latin American decent so let me know anybody who can fit that roll.
South America was basicaly an alternative Earth until the American interchange, truly fascinating
good luck getting that documentary
Maybe Natalia Oreiro, Gael García Bernal, Ricardo Darin or Guillermo Francella.
There is "Life on this Planet" show, but the Tbirds dont get enough screentime. Very well done show though.
@@StevieSeagal Oh yeah I have seen that show, Netflix cooked peak with that one
This terror bird looks kind of like the Shoebill (Balaeniceps rex) alive today. Very interesting video!
Yep
That shoebill bird can look terrifying but those derby eyes makes it look kinda cute when it looks at you 😅
Ever since I've heard of terror birds, I've thought of them whenever I've looked at a shoebill at the San Diego Zoo Safari Park. Before that, I thought of T-Rex.
They also look like the seriemas Oh wait, that's because they are
To bad theses aren’t alive anymore
0:57 Cassowaries would like to have a word
Its actually extremely possible that humans and terror birds might have briefly overlapped, the date of human migration to the Americas keeps getting pushed farther and farther back with a mastodon recently found in California that is 100,000 years old and was possibly either killed or scavenged by ancient humans or maybe even neanderthals.
They still are, seriemas
doubt it. how long would humans survive 10-pound fried egg breakfasts?
@@frowner_and_coSeriemas are not terror birds. They are merely relatives
So modern avian dinosaurs aren't intimidating? I think the cassowary would like to have a word with you 🗿🗿
I keep a few chickens, and I love them but I looks at them and you can see the dinosaur in them, imagine them 10 feet tall and they'd be terrifying. They are voracious, fast and dumb, which is cute only because they're harmless and have prey animal traits like being scared of strange shapes and noises, I know they'd eat me without thinking about it if they were big enough.
When I saw a reconstructed T-Rex in a museum I could very well imagine it bobbing its head as it walked, the way a chicken does. BTW, terror birds were closely related to parrots. Ratites are the basal extant birds, and ostriches are the basal extant ratites. So genetically, ostriches are the closest living species to non-avian dinosaurs.
Interesting stuff! I'm old enough to remember when the whole "Birds are related to Dinosaurs" thing was just the province of maverick palaeontologists. And remember, that was "related to", not "are". Things have really moved forwards in the last 30 years. And I'd not even heard of the Terror Birds until quite recently. So, basically a terror bird is kind of a short-tailed, beaked, mahoosive dromaeosaur, kind of thing?
Gotta love that bunny eyeball at 6:41.
I’ve been bitten by an ostrich hard enough to draw blood. These -birds- _dinosaurs_ are no joke.
Smilodon: HOLEY SMOKES HE’S A DINO! Terror birds: Not just “a dino!” Remember me mammals? When I ruled this planet, I roared…just…like…THIIIIIIIIISSSSSSSS!!!!!!!!
As Dinosaur we do be making comeback amd this time we're here to stay. Not even meteor can stop us.
Reading this is weaponized autism for the eyes.
This has reignited my interest in the Moa, the giant flightless bird from my country, Aotearoa (New Zealand) which went extinct around 1445
My interest too. Actually, their extinction is all the more tragic as I think they survived clear up into the time of photography! I'm not sure, but I swear even seeing a picture of one. We'll have to look it up.
@@kennethmartin1300 I think you are right and there are a couple of photos of them, but I could be mistaken. Let me know what you find!
I’d love to see a video on the teratorns soon. They seem to be overshadowed by the terror birds a lot of the time.
The largest one was ridiculous, the size of a grown human, and yet somehow could fly.
What is the official explanation to Eleutherornis being found from Europe? either this bird isn't related to the real terror birds or there's a whole massive epoch of time missing from its lineage.
When the mammals thought they caught you lacking so you gotta remind them why they stayed small for over 160 million years
To understand what may have happened in the past you have to look at more recent events. A lot of our birds have gone extinct or close to extinction when something new is added to their environment that could have possibly destroyed their nests and lowered their ability to procreate. Nothing has been said about their parenting skills or if they had them at all. A mammal could have been responsible for the destruction of their nests.
The Forest Rockets, the scariest birbs. Ever since I was little I always heard the name wrong but it helped me remember it easily
Great work as always! Bird evolution is easily the subject im most interested in ❤
Top quality illustrations, animations and organisation. 10/10. The best compilation I’ve seen about the Phorusrhacids.
Nice video, very informative! Didn’t know much about Terror Birds!
I think it's interesting you suggest that the heavier bird likely preferred more open habitat vs. Titianis preferring more forested ground. I would think the heavier ambush hunter would benefit from some cover, whereas the faster, more nimble Titianis would do better on more open ground. But that's just "logic" I have no facts to back that up.
It's hard to fathom the extraordinarily dramatic changes to the countless animals that have inhabited Earth over very many millions of years. If there's another planet truly Earthlike it's probable it also went through similar changes, and now it's just waiting for us to discover it and make plans to go there. It's weird to think about another place geologically and meteorologically similar to Earth that had a much different past "cast of players", as has occurred here, and now it's populated by Monsters we've not even imagined. SIGN ME UP!
The worse thing to happen to another planet would be for humans to go there.
Thank you, an intresting and good explanation on the Terrorbirds, i never knew that they reached europe. Keep up the good work.
1:44 That's insane! I didn't realise how massive the larger ones were.
Having sadly been born and raised into a YEC cult environment that had its claws in me for 25 years, I always love seeing videos like these which are so informative about the wondrous, incredible real-life history of our planet. Even if it gets me feeling more than a little existential about how relevant and important humans really are in the grand scheme of things.
Glad you found your way out of YEC.
@@mattryan6886 Thank you. 😭
If you think about it, the fact that we are not "special and superior" to these animals in a religious or divine sense makes us far more unique, because we had no help from a god or a creator who set us up for success; the circumstances simply lended themselves and we adapted accordingly. We might not be that grandiose, favorite child most religions talk about, but to me that just means we're amazing in a far more natural and factual manner.
@addictedtochocolate920 I like this take! I do often wonder, "why us?", but the absence of divine help does make it so much more interesting!
@@HalloWitch93 Why not us? Chaos, although often depicted as a negative concept, is a beautiful thing. We're here and things turned out alright. Maybe we're not that rare, it's just that we don't understand the space that surround us properly. Regardless of how you see it, we rarely get the chance to fully rethink how we see the world as a whole. Hope you find a satisfying one.
It's unsurprising that smaller prey shows up on the Terror Bird menu. Large predators, though capable of bringing down larger prey, seem to make good use of plentiful small varmints for a variety of reasons. Sheer numbers, of course- there's generally no shortage of insects, rodents and other "street food" available to crunch down. With smaller size there is also lower associated risk of injury to the predator. This is important because any injury, even if not initially fatal, can become so through infection. Oh, and then there's the obvious: rats and bugs are just so damn tasty!
Bird-watching back then was an extreme sport.
Everytime someone tries and say, ‘why didn’t dinosaurs comeback?’ I always think to myself that terror birds and cassowaries, are and were a thing.
Terror birds are still here with seriemas
This is a great show. Thanks for giving us a tour of the terror bird clade
Just want to say thanks for your amazing productions. Have watched many of your videos now and found them very impressive.
Very interesting. Enjoyed this! Thanks Extinct Zoo.
So that mean we did live with fully carnivorous dinosaurs!
Dang, I didn’t know that eagles were facultative carnivores
Superb research and presentation, as usual.
If terror birds were still around, we could've had chocobos.
DNA has shown the family relationships between present day large flightless birds is totally not what we thought ! It would be interesting to see how these creatures would fit in but there is probably no way to know..
They are not related to ratites. They are closely related to the seriemas, and with them are a sister group to falcons, parrots and passerines
Ratites are much older group than the terror birds. Ratites existed alongside the non avian dinosaurs.
They still do with seriemas
As a zookeeper I can tell you that ostriches can be pretty fearsome I can only imagine what Terror Birds would be like.
funniest thing about birds being dinosaurs is that they're the most diverse land vertebrate, so there's still more dinosaurs than mammals lol
They are still Dinosaurs. Birds did not evolve after the Dinosaurs were extinct, Birds evolved alongside Dinosaurs. There are even Fossils of Ducks from the Late Cretaceous. Birds are Dinosaurs as well. We just learned about their existence before we learned about the existence of Dinosaurs so we didn’t name them properly until we had the necessary information to do so.
It always surprised me that flightless bird’s wings never evolved into arms and claws, or even grasping hands.
Their biggest limiting factor is a lack of a tail. It's the only thing that prevents them from attaining the size of the non avian theropods.
Evolution doesn't have targets, if they thrive without hands, they won't develop them.
Outstanding presentation with visuals and narration that holds one's attention.
I just found this channel and I dig it. I've been looking to learn more about prehistoric animals lately and I think this'll help. On another note: I like terrot birds because they featured heavily in one of my favorite shows.
Very interesting video indeed!
Excellent Extinct Zoo! Great info on a family of extinct birds I was interested in for years, but could find little about.(Guess I didn't look too hard,my bad.)
I love the terror birds, such a fascinating animal group. What I really want to know though is how having a beak change the way these dinosaurs hunt compared to their theropod relatives? Is the beak stronger than the theropod skull? Did that make them lighter, and thus, faster?
Humans were in South America way before 16,000 years. Recent findings have pushed it back to at least 20,000 years.
It took well over 10,000 years, and probably more for them to become extinct, according to paleontologists.
Lovely as always.
I can definitely see how these things got their name!
They didnt go extinct they just got smaller. I own a terror bird(green cheek conure) she terrorizes me everyday
Terror birds taste like chicken
☹️
Its delicious
Is this scientifically proven?
There is such incredible paleo art in this video omg. I’m trying to find them all to save them for inspiration
Had a Terror Bird model when I was a kid. Neat vid.

Great review.
ExtinctZoo best upcoming prehistoric creature channel frfr
Don't forget CHimerasuchus and Dr. Polaris
That is one awesome thumbnail!
Do you think their size compared to their weight gave them any advantages compared to mammalian predators? Largest ones seem to be about the same weight as an large tiger, but so much bigger. Imposing advantage, reach, power etc?
Yeah, probably. Also tiny brains generally mean unbridled aggression. The terror birds truly deserved their reputation.
@@raylopez99 hmm not sure how plausible the tiny brain thing is. Couldn’t find anything that suggests that is true. And bird brains are different from mammalian brains as they are built a bit different and they are more efficient.
@@Makabert.Abylon +1 for bird vs mammal brains, but keep in mind the dumbest mammals are the marsupials, which have tinier brains than placentals. And they tend to be very aggressive. Think about that dumb bully that is often found in US schools, and later they end up with some menial job after high school.
They would have been at a disadvantage because they have no tail. No tail means inefficient balance and a limit to their max weight.
So... the dinosaurs tried a comeback, but thanks to a coalition of jaguars, wolves, and... er, glaciers, they were defeated just in time! Good stuff.
The introduction of Titanis Walleri in Cage of Eden was absolutely terrifying. Really lived up to the title of Terror Bird. It was made even worse by their first appearance being the end of my reading session before bed, so my brain came up with all sorts of nightmares that night until I could continue reading after work the next day. Somehow my nightmares were far worse than what actually happened.
Polska Górą! Dzięki za polski kanał!
Dinosaurs were in some ways better involved and designed than mammals. 3 things about dinosaurs. 1. They perhaps had bird like more efficient lungs enabling larger animals. 2. They probably had lighter stronger bird like bones again enabling larger animals. 3. They may have had bird like tighter more efficient neurons so despite having small brain cases they may have been intelligent similar to some modern birds. Mammals however may have held the trump card of live birth which made the difference between dinosaurs and mammals allowing mammals to take over. It’s also possible that mammals finally finished off dinosaurs. Perhaps dinosaurs would have made an eventual slow comeback but the mammals back then were small rodent like burrowing creatures living on whatever they could find like decaying animals, plant roots and dinosaur eggs and eating those eggs finally doomed dinosaurs to extinction. Even today ship rats escaping onto islands can wipe out ground roosting bird colonies. I think as well the Earth’s atmosphere may have been thinning enough to lower global temperatures and this may have helped to end the dinosaurs.
Your example of rats wiping out ground nesting birds on islands ignores the fact that ground nesting birds also live on continents with much more mammalian competition. The fact that the birds lived on an island free of competition contributes much more to their extinction than the fact than they are ground nesters. Even birds that nest in trees that live on islands have been wiped out by invasive species. The same can be applied to dinosaurs, if they were successful enough to survive before the asteroid impact, then they would have survived post extinction. What would have changed to give mammals such an advantage in such a short period of time? This also ignores the fact that the dinosaurs would have much more mammalian competition pre impact because mammals also suffered during the extinction losing like 70% to 80% of species.
@@chrisdonish all species would have been on an extinction precipice. Presumably small burrowing mammals survived by eating anything available and them eating dinosaur eggs when that species were in low numbers might have made the difference between survival and extinction.
@alexbowman7582 it's way too outlandish of a theory for me to believe. What are you implying is that every single surviving dinosaur would have 100% nest failures due to predation which we don't even have any evidence that mammals were even capable of attacking their nest and we also don't know what nesting strategy all dinosaurs used because if they were anything like birds or crocodiles, your theory is impossible because they would have been guarding them. We do know that oviraptor brooded their eggs because one died on her nest so we could assume that all dinosaurs closely related to her would have done the same but we don't about all other dinosaurs. Way too outlandish for me. I simply don't see it being possible.
These must have been extremely dangerous and scary animals, but I'm kind of sad that they aren't around anymore. They must have been majestic.
Terror birds have got to be my favorite group of Cenozoic animals. Just a shame they aren’t around anymore, just like many other megafauna of South America
This is what Trex would have look like if given enough time. Larger but maybe something like this
Great video...👍
Great video
*Xcellent doc*
Damn that imagery at 6:35 is soo hardcore lol... the eyeball popping thru , really?? Lolol
Yeah I personally wish the Terror Birds were still around. Them and the terrestrial only crocodilians.
Have they considered that the EGGS of Terror Birds may have been targeted as food by another animal, thus leading to their extinction?
Awesome Channel

Cool vid.
Hey, just a request, could you do deinosuchus or smilodon please? thanks
I love how some art makes them look like giant secretary birds
Any theories on whether they were solitary or pack hunters?
Not really but as there were a lot of species of terror birds its both is possible in diffrend species. Its also possible that they lived in mated pairs as a lot of birds tend to do that as well
Great video.

That thumbnail is brutal 😮
Not all non-avian dinosaurs even by the end of the Cretaceous were huge - the surviving birds' advantage wasn't just smaller size, but among other things included the ability to fly and thus have more options to find food that hadn't been completely wiped out.
