I honestly still feel that the depiction at the end is somewhat inaccurate, Given that Phorusrhacids had evolved to become fierce intelligent predators in their own right it so unlikely that they’ve been outcompeted by mammalian carnivorous when the birds are more than capable of fending off against them or even as a group for that matter. And not to mention the fact that based on findings of smaller relatives surviving up to the later late Pleistocene, I feel that climate change had more to do with this then this outdated cliche. Terror birds depicted in the series in my opinion should deserve better than this.
You're almost certainly correct. Phorusrhacids crossed into North America and survived for millions of years with all the other large mammal predators. From California to Florida, coast to coast. Big mistake by the writers and editors. We still don't know a lot about terror birds; most of the fossils of the larger ones are incomplete and fragmentary. We still don't know for sure how they hunted and what they ate. They may not have been apex predators. They may have hunted smaller animals or had a niche role like scavenging so they wouldn't have to compete with the other large predators.
@@krismichael1633 Titanis was the largest predator of it's time and was really 4 times larger than Smilodon gracilis and it was also larger than homotherium and Xenosmilus , so Titanis was the apex predator of it's region , likely hunting horses, ground sloths and the smaller rodents which would have also lived there .
@@krismichael1633 Based on evidence found in the area where Titanis lived and also based on assumptions made from terror birds which lived in South America , and since those hunted ground sloths and notoungulate then Titanis was well equiped to take down these animals. And the part of it being an apex predator, well Titanis was larger and heavier than all the carnivores it shared it's area with and the only reason why they evolved larger sizes was because the phorusrachids went extinct and it wasn't the cause for their extinction .
@@Xbox-with_extrasteps What evidence in areas Titanis lived? You need to post links. What evidence they hunted sloths and notoungulates? It wasn't 'equipped' to take down those animals. It could kick large rodents and small litoperns. Then rip them apart with their beaks. But this is all speculation. Even the idea that it hunted large rodents. It could have been a vegetarian, cracking nuts and fruits. Lots of animals killed by Homotherium and Smilodon have been found. No Titanis kill sites have been found. You're simply making up fan fiction. Titanis wasn't the only 'Big Bird'. They lived on every continent right through the end of the Pleistocene on every continent. None were 'apex predators' although some were probably predatory. In Titanis' case we have the Big Bird but no dead Sunffaluffagus...
I'm a huge bigcat fan, but Titanis coexisted with Smilodon gracilis which were not big enough to challenge adult terror birds. However at that time there was a bigger sabertooth cat known as Xenosmilus which may have killed both terror birds and S.gracilis.
Xenosmilus would have been able to kill S. gracilis (and actually DID, based on Xenosmilus feeding sites where the kills dragged in included S. gracilis), but when Titanis was around it was still only around Jaguar-sized (with gracilis being leopard-sized). Once Titanis went extinct Xenosmilus got bigger (tiger-sized) and briefly replaced it, only for it to go extinct from the same causes shortly afterwards (not even half a million years later), allowing S. gracilis to take over (going from 55-60kg to 100+kg) and later become S. fatalis (250-300kg, the same size as Titanis used to be). Titanis itself started out as a leopard-sized predator in the Early Pliocene when Amphimachairodus coloradensis was around. When that thing went extinct halfway through the Pliocene it came down to Titanis or one of the smaller sabretoothed cats to get big and replace it, and the bird managed to beat the cats to it. So there was a succession of tiger-sized land predators with neck-driven cutting bites dominating North America, dying out from climatic factors, and then being replaced by a leopard-sized or Jaguar-sized predator that got bigger to fill the gap (tiger-sized Amphimachairodus and leopard-sized Titanis and Megantereon => Amphimachairodus goes extinct, tiger-sized Titanis and leopard-sized Megantereon, which then evolved into the leopard-sized Smilodon gracilis and coexisted with the Jaguar-sized Xenosmilus => Titanis goes extinct, tiger-sized Xenosmilus and leopard-sized S. gracilis => Xenosmilus goes extinct, S. gracilis gets bigger and then gets even bigger when it evolved into S. fatalis => S. fatalis killed off when humans start to dominate in North America, especially since seeing as it was specialized for warmer forested habitats and thus would have benefitted from the end of the last glacial period)
@@knowncoralconsumer there’s also the fact that sabertooth cats were generally more heavily built than other cat species and therefore less agile, so it’s not like they’d be able to jump on a titanis back or throat in a direct confrontation (especially when you look at how tall a titanis is compared to a smilodon gracilis). There’s also the fact that terror birds have much denser bones than the majority of other birds, so they could probably take more of a beating. Then there’s the fact there necks were well built to withstand dorsoventral stress meaning they could jab downwards with extreme force. A single well aimed jab to the head or spine and the smilodon is either dead or paralysed. Sabertooth cats were likely mostly ambush predators to begin with.
Yup, your 100000000% ! Correct on that, terror birds would be more than a Match for a smilodon. The powerful robust recurved beak with strong neck muscles, it’s robustness and Cursorial build, and feet with sickle like toe claws much like a raptor such as the well known very large utahraptor, are very formidable tools at its disposal, and would do a a whole lot of.
The fact that terror birds actually EXPANDED their range when coming into contact with the northern fauna should be evidence enough that northern predators didn't wipe them out, but I guess not...
Not to mention on their intelligence, if anything hypothetically speaking in a speculative sort of way for all we know they could had maybe lived in a group like Harris Hawks for example. This series while cool is it is should had plan out more especially on accurate depictions
Terror bird 1: “This pond isn’t big enough for the two of us.” Terror bird 2: “Oh yeah? I’ll dance to that you overgrown sparrow.” Terror bird 1: “I’m as badass a Big Bird as you are.” Smilodon 1: “Hey, come on, Bob. Chicken for lunch.”
I will give credit to the way the terror bird fight is depicted. Rather than being shown as two males pecking each other to death, the fight is, for the most part, a series of displays, meant to intimidate the rival without causing bloodshed. This is how infraspecific competition often occurs in the real world.
Still, the terror bird could put up a good fight and in some instances even killed saber tooth cats. It's just that here one bird was taken by surprise and the other decided not help, since the death of a rival is beneficial for it.
@@brandonkey181 there absolutely is evidence that titanis was the dominant predator in its environment. The presence of Titanis in the ecosystem was most likely what stopped Smilodon Gracilis from getting larger and evolving into Populator, since they only started getting bigger once Titanis had disappeared
It's more of an estimated guess. We compare extinct animal to living ones to fill in the blanks. In this case, birds. Some animals do leave tracks that give us an idea of what their dances were like. All this helps to a clearer picture of these animals' life styles.
Should have added in case you didn't know. These guys aren't 'dinosaur-dinosaurs'. The ones that were around with T-rex, stegosaurus and the rest. It's descended from the birds that survived the mass extinction that wiped out the rest. It's ancestors could fly but it grew so big it became flightless. Like an ostrich. It lived millions of years afterwards during the age of mammals. A hint is that sabre-tooth cats didn't co-exist with the non-bird dinosaurs.
This feels like it was originally intended to be a _courtship_ ritual (because that's what birds who do the whole "synchronized dance" thing use it for) and then one of the higher ups changed the narrative at the last minute to make it more "badass." Which is then subverted by perpetuating the "sabre-tooths drove terror birds to extinction" myth.
How the F would they know the precise behaviors of these millions years old animals? I feel like people just make shit up and we just take it as fact because they’re scientists.
I don't know how accurate this feeling is; towards the end of their reign, this is what the mighty Tyrannosaurus Rex may have looked like. A twenty five foot long flightless bird of prey.
Not gonna lie, I love prehistoric documentaries like this, but I love Morgan freedman’s so much it soothed me to sleep. For the entire season. I passed out cold for the whole season during the second episode
А lot of unnecessary attacks and shouting. Look at the battles of modern cassowaries: a couple of poses, a sharp throw, a series of exchanges of blows accompanied by a terrifying hiss, the loser quickly runs away, and that’s it
Birds of Prey (order Falconiformes) are a very large and diverse order of birds, filling many ecological niches, there are only nine extant families of birds of prey, Cariamidae (Seriemas), Sagittariidae (Secretarybird and Fossil Relatives), Aquilidae (Eagles), Accipitridae (Hawks, Buzzards, Harriers, and Kites), Pandionidae (Ospreys), Aegypiidae (Old World Vultures), Caracaridae (Caracaras), Falconidae (Falcons, Kestrels, Hobbies, Falconets, and Montanaguila), and Cathartidae (New World Vultures), there are also extinct families of birds of prey like the well known brontornithids (family Brontornithidae), the dromornithids (family Dromornithidae), the gastornithids (family Gastornithidae), the terror birds (family Phorusrhacidae), and the teratorns (family Teratornithidae).
All this design needed to be peak would be a sickle claw for holding down their food since their closest living relative the Seriema has said claw and we have terror bird foot prints that show they may have also possessed said toe claw. Convergence is an amazing thing
It’s very very unlikely that smilodon could be considered the primary reason for terror birds extinction. The primary reason is more likely to have been drastic climate change from the beginning of the Pleistocene with its extreme colds and ice ages distrusting the birds habitat
"The two begin a ritual display, assessing the others' strength while showing off their own." Yeah, uh, that is pretty blatantly a MATING DANCE more than anything.
All these people in here clearly didn't pay attention to the narration. The documentary doesn't say the smilodon was THEE only reason the terror birds went extinct, it said they were "one of the reasons" meaning there were multiple others.
I was messing around with Mad Science and found out that if you mute the narration and play Michael Jackson Beat It it just works perfectly with the animation
El diseño de Titanis está muy delgado, en realidad sus patas y cuello eran más robustos. Era muy difícil que un Smilodon fatalis se enfrentará a un ave depredadora de esas características si consideramos que actualmente un águila real es capaz de espantar zorros y hasta pumas, las aves son animales de sangre caliente también y pueden ser muy poderosas y agresivas
Hopefully no one thinks these artistic renders are close to real. I mean, they are works of talented fiction based off bones with no feathers, that ARTISTS, not scientists, captured the colours, feathers, eye and skin variations of this bird. Obviously the sounds are pure fiction too.
In this particular case, it's looking at modern animals and filling in the gaps. Modern birds do elaborate displays for social interactions, so it's a logical conclusion that terror birds likely did the same, especially since terror birds are closely related to extent birds like Seriemia
