This video looks into the giant predatory birds that lived in south america after the dinosaurs died out up into very recently. There have been many predatory bird families but the phorusrhacid were the largest and the existed for the longest time.

I heard "forest rockets" instead of "Phorusrhacids"
These forest rockets will get us to mars.
For a moment I was confused as well lol
Michaël Dorfman i wouldn't have known it wasn't forest rocket if you didn't comment
Same here
Watch the video again with subs and laugh a lot
Other people: "Terror Birds"
Me: *F O R E S T R O C K E T S*
Lmao
Those birds must have been really fast to have the nickname "forest rockets"
If I had not looked at the comments I would have actually left believing they were called forrest rockets
@@phae_c oh gosh me too. It was a weird descent into the comments. I first I thought it was a troll, then I realized I actually also misheard.
The captions have it written like that lol
The judges will allow it this time, but one more pun like that and you'll get a penalty.
Acci I know right XD
This entire time I thought he was saying forest rockets. I just agreed like it made sense.
Same
wait he wasn’t saying forest rocket? 😂
I wouldve gone the rest of my life thinking they were forest rockets if it weren't for your comment.
@@lilfroggo9897 he was saying phorusrachids
I say we should all agree to rename them as forest rockets
I’m calling terror birds “Forest Rockets” from now on. You have started a movement.
Forest rockets is such a cool nickname, im adopting the term too
He’s actually talking about Phorusrhadis, he just has an Accent..
@@l1xs4ndr0. We know

10:19 "the theropod dinosaur niche was being filled up until only a few millions years ago"
By theropod dinosaurs nonetheless!
Haha yes I guess you're right
i'd say the niche is still being filled, just mostly by mammals now. Same niche, just different animal filling it. Birds never did a great job filling the niche if we're being honest.
@@trvth1s Birds FLY
That's all I have to say
If you think about it, none of the features of terror birds are all that out of place amongst other dinosaurs. Plenty of theropods with feathers, plenty of dinosaurs from different families with beaks of various forms. The shortened and fused tail is probably the strangest thing.
@@edoardocastelnovi7154 birds also have a major size restriction due to their skeletal structure. You can't be a dominant megafauna if you can't get very big
I keep thinking that you’re saying “forest rockets”
Hey that's a good mnemonic trick here! ;)
I hear that or forest rockers..
I thought is said that on purpose.
he is not?
@Adinan Cenci he’s saying phorusrhacid
and no plastic lizards were killed in the making of...
Press F for the plastic lizard.
Im from brazil and frequently see seriemas in my grandpas farm, they are quite elegant animals, always seen in pairs and sometimes groups of 3 or 4. When i look at then, i see dinosaurs clearly, the way they run looks a lot like the velociraptors from jurassic park, its amazing
Yes; I've seen such a beauty in real life. Sadly, it was in a small cage and had nowhere to run. Have you seen them run?
@@dondragmer2412 I live in Brazil too, I was camping once and when I opened the tent in the morning there was a couple of seriemas walking less than two meters away, it was an amazing experience. They are quite common on the countryside and often come close to humans, people don't mess with them because they eat mice and snakes, so they are good allies of farmers.
It's not common to see them running, though. They are always walking elegantly, and even when we approach they run only a few meters and then come back to walking again.
When I see marabou stork or even chickens I see dinosaurs. Cassowaries are probably the closest though.
@@dondragmer2412 I mean he clearly commented on how they ran so I'd guess yea he's seen them run.
Apparently you were NOT saying "forest rockets", but I'm glad I'm not the only one who heard that every single time
this whole video i heard "forest rockets" instead of "phorusrhacins", which is admittedly just as intimidating as "terror birds"
the forest rocket is my favorite kind of goose

"Phorusrhacids", apparently. i thought he was saying "forest rockets", too.

Closed Captions are great in this video. "Forest Rockets" "Back in the Maya Scene" "Kevin Ken" "Brawn Tallness" "Full grown Sorry Emma".... GOLD!
Some birds are still apex predators, though they dont exactly compare to the terror birds otherwise.
He wasn't saying all birds he just said terror birds
Probably more accurate to say that they no longer occupy the same niches - ground dwelling apex predators in habitats good for running or ambush.
@Frank Wharton-Hughes apex predator of new Zealand was the haasts eagle before he went extinct and the crowned eagle In Madagascar was also an apex predator I believe same as terror birds at their time.
Frank Wharton-Hughes
Most apex predators will kill (and be killed by) other apex predators.

Me: LOOK AT ALL THOSE CHICKENS
Before Angry birds..
There were terror birds
Maybe they were also angry .. hence .. the terror
Bird isis.
I'm in total confusion, I wanted to call it “Phorusrhacids”, but “Forest Rockets” seems cooler. “Terror Birds” may also do, but we all know which is way cooler. Honestly, They seem like an underrated basketball or sports team XD
One of my favorite post-cretaceous extinct animal groups.
The fact that this channel is still as small as it is makes me confused. I really would argue that this channel is the best channel about presistoric stuff, even beating out pbs eons in pure quality. And in terms of a constant stream of excellent content I really would argue that this is the best “prehistoric stuff” channel on UA-cam right now period.
Greenfors! Thank you i appreciate it
Moth Light Media I have to agree with GreenFors here , thanks for the great content too .
Thanks man
PBS Eons has posted more than a few inaccuracies (including those that make no sense whatsoever). I especially find them to promote debunked or questionable ideas about some animal groups driving other animal groups into extinction.
I often wonder this as well I only just found this channel but Im not understanding why its not more popular.
T. Rex: "Man it sucks having these tiny useless arms."
Phorusrhacids: "Hey at least they're the size of muscular human legs, and have claws. Check THESE puny guns out - TOTALLY useless."
Carnotaurus: I know how that feels
images.dinosaurpictures.org/carnotaurus_355f.jpg
I would have to double check, but I am pretty sure tyrannosaur arms were a bit stronger than the average human leg I think I heard an estimate of being capable of lifting roughly 400 pounds which is about the most my legs have ever been able to lift combined.
Weren’t Tyrannosaurus arms pretty strong though?
@@jayfeatherthesnarkymedicin8160 they could probably lift roughly 400 pounds each, which isn't very strong for a tyrannosaurus rex sized animal.
@@RocketHarry865 You're the mini-arm champ, Carno.
Oh man, I'm so glad the top comments heard "forest rockets" too. I didn't realize what he was saying until it was printed onscreen. I didn't think it was the scientific name, but maybe like how roadrunners got their name?
This has got to be the very first time I've ever heard of anyone referring to the terror birds as "forest rockets." And you know what, that's such a damn cool name to call them! I shall probably refer to terror birds as forest rockets from now on! :)
I had always pronounced it "fores raysids." Maybe I was wrong. I think at one point the narrator himself commented that, no , don't confuse them with space rockets.
he was actually saying "phorusrachids" but it just happens to sound like forest rockets xD
Imagine how happy they must be. The thousands and millions of years later, we know them as legendary Hunter.
The modern secretary bird of Africa, about four feet tall, though not related closely to the terror birds, is kind of a modern small "terror bird," convergently evolved to a similar life style and form. It is a member of the same order to which raptors belong, but has its own family, the Sagitaraiidae. It's famous for hunting snakes as well as lizards and rodents.
there was another bird that was closer to terror birds
it’s beak shape shows it but it was more friendly: dodo
interestingly the secretary birds hunt primarily by stomping while recent discoveries have shown that terror birds(at least some of them) had a claw they kept raised and therefor sharp likely used to restrain their prey. So both convergently relied on their legs to a large extent. The terror birds tho taking the more dinosaur and metal route.
This is definitely my favorite channel on UA-cam, keep it up man.
Thank you that's awesome to here

@@KK-bt6nc are you saying forest rocket
I swear he was saying, "forest rockets".
Oh, apparently everyone did.
That's how the caption presented his voice.
Julio Lacerda is such a good paleo-artist. Beautiful work and I'm happy to see it featured on such a high quality channel.
A smal mistake, Seriemas are able to fly, similar to roadrunners they live only mostly on the ground.
Hail Giratina The True God
I was thinking that, too. Thanks for confirming it.
It really is crazy how perfectly south america fits into the west coast of africa
6:22 I literally thought phorusrhacinae was a pun on forest rockets because they're fast and live in the woods, and brontornithinae was a pun on born to run because they run instead of fly.
Well bronto is thunder in Greek, so I assume their name translates to thunderbirds, which is pretty cool.
@@JohnyG29 not as cool as forest rockets and borntorunithids
It looks like the algorithm has noticed your channel. Good to see your subscription count growing.
One of my favorite paleo species. I cannot describe how much I love these videos and their ability to be so interesting and informative
I'm glad I'm not the only one who heard "forest rockets" instead of "phorusharcids"
8:19 I never understood that pic
Great presentation. I believe New Zealand had a bird as the last apex predator of any country, in the form of the Hast Eagle. This bird survived up until humans killed off most of their prey approx 600 years ago. Its main prey were various species of flightless birds in the Moa family.
yeah people probably killed and hunted it to humans arent really appreciative of a bird that can pick up and throw kids
Moas, giant Kiwis! 🤭
@@jzjzjzj yeah giant eagles specialized to hunt bipeds sounds like something I wouldn't want to live near
After the extinction of most theropods ... Theropods still dominate today.
Even the CC auto-generates "forest rockets" lol
4:30 Off-topic yet their distribution is quite similar to certain freshwater fish often popular in the aquarium hobby. Like the rhea found in South America and the ostrich found in Africa; the relatives of characins which are piranhas, and tetra fish are found in South America and tetras inhabit both Africa and South America. The relatives of arrowana fish are also distributed in a similar range yet from Asia, Africa and South America.
I wonder if those fish groups also have an ancestor that traces back to Gondwana
Imagine being so badass that "Terror Bird" isn't even your coolest nickname.
Everyone saying “forest rocket” sound like a cool name but “terror bird” is metal as hell
Forest rocket, forest rocket, FOREST ROCKET!! FOREST ROCKET!!
I'm sure you know this now but birds, all of them, *are* theropod dinosaurs.
can we PLEASE start calling these guys "forest rockets" like we all thought he was saying, that is the single sickest bird name ive ever heard.
I am here to tell you that in the soon future your channel will blow up. Your video was recommended to me at 2.3k views, I think the algorithm has chosen you next
I hope so
@@mothlightmedia1936 And it did lol
Gondwana hadn't existed for millions years by the time of the Cenozoic, Gondwana was a thing in the Jurassic.
The forrest rockets! A fitting name.
Ranks up there with the best I saw on the subject - the extinction theorem helped.
Subbed.
Phorusrauchids... 😂
You've just made the whole reply section to go *DEFCON 5* over that "Forest-Rockets" racket.
It feels that tags with every term and name you pronounce in a vid is of the essence.
Keep up the good work!
Literally found this channel today, and with it my new addiction to these videos.
Man... 7 year old me wishes he had access to this awesome channel. 23 year old me is arguably just as happy tho
One of my favourite channels man, thank you
S America wouldn't be the last place with bird apex predators, that's pretty much all of what New Zealand was about. Love the channel!
I am just floored by your work, So very few ever cover life before and after the Jurassic period and never as good as this, you should be teaching this in school, Very well done.
All excellent stuff; prehistoric life is fascinating indeed.
Ive seen almost Every video you’ve got.. and loved all!
3:50 Gondwana started splitting in the Jurassic, long before phorushrachids evolved.
Yeah he's got some huge errors on plate tectonics which causes errors eleswhere...
Ah. "Phorusrachids,"
instead of "forest rockets." Got it. Lol
If it wasn't for the comment section I would have been that guy telling my friends about the " Forest Rockets" haha
I somehow heard the name as "Forest Rocket" 🤣🤣
Forest Rockets. I've watched this video a few times, cannot unhear it.
I'm so glad I'm not the only one that was hearing "forest rockets" 🤣. These comments did not disappoint!
Just found your channel. Loved it instantly.
Thanks for watching
Could you imagine a large carnivorous bird running at you at 60 mph? Holy shit!
60mph is too fast for such a large animal. 30mph is more realistic.
I actually googled forest rocket until I read the comments LOL
I can't even imagine how one must of felt if they stumbled upon one of these things while out hiking in the woods! Holly heck! This IS a straight up BEAST!!!
This channel is amazing, I wish you get more features and more subscribers in time
Terror birds were my biggest ops when I played Ark
Great video-I have always been fascinated by the ancient world...
Always good! Thanks for your take on these fascinating animals.
Thank you
Thank you
Thanks man
I learn so much from this channel
Forest rocket seems apt.
lol even the auto translate captions heard it as forest rockets
Well, the extinction of those large birds in south Amerika alings with an iceage Event in the southern hemisphere .
There are remains of glaiciers present in argentina and brasil that are dated to be 20 million years old .
Damn 60 MPH?? That is crazy-Humans prolly wouldn't stand a chance and apes being more nimble might be able to evade...Yikes-the stuff of nightmares for sure...
3:43 the first half of the Cenozoic South America was connected to Africa and Antarctica as part of Gondwana? I'm pretty sure Gondwana had more or less completely broken up by the beginning of the Cenozoic, barring a small land bridge between the Southern tip of South America and Antarctica.
yeah big errors here
They should really change the name of the animal category to "forrest rocket"
beautiful you tell it so smooth thanks for your work
Thank you, I appreciate it
Had to watch this twice because I was giggling at the Forest Rockets.
I went to type something about forest rockets and realized that’s not what was being said lol
Really enjoyed that, thanks
I tamed terror birds in mortal online mmo , was one of the coolest games to have this creature in them but they weren’t as badass as they could have been .
Forest Rockets are really awesome, thanks for this video :)
Moth Light Media: "The Forrest Rockets were the last apex predator birds."
Vatican-based cardinal: "Am I a joke to you?"
Yes, you're an evil joke; but not a funny one at all.
Weren’t Africa and South America already separated by the mid-Cretaceous?
Yes
this confused me as well
I hear forest rockets too. Also, while I know it would be terrify and that one's life expectancy would be greatly curtailed, I can not but think just seeing these terror birds living their day to day life (assuming they are not actively hunting me during that time) would be ever so interesting. The flightless birds of today are interesting, if rather boring, but a terror bird. Something mover 7 feet high, and weighing as much as an elephant. Thundering and shreiking across the pompas in pursuit of prey. To see it rip and rend at the fallen victim's flesh as it fed. Amazing. Come on, someone, invent time travel while I am still young enough to do this.
they were tall but they were still birds so built lightly. Did you know ostrich of today can be 9 ft tall!
Also; no bird ever weighed as much as an elephant, much less a terror bird. Terror birds got as big as big cats, probably quite a bit smaller. The biggest bird ever, as far as we know, was a vegetarian which weighed as much as bison. Birds have a major size restriction due to their stance. Birds have a crouching stance because they became front heavy when they lost their bony tail in the jurrassic.
Nonavian theropods had a bony tail so the big boys, like trex, had a column stance which can carry a lot more weight more efficiently. We have a column stance ourselves, we have a lot of potential and have grown a lot the last millions years.
@@trvth1s The largest terror birds reached sizes comparable to the larger big cats, though many were smaller.
Forest Rockets? 😂They must have used those huge beaks like machetes to clear paths through the forests of pre-human Earth and move swiftly through the trees. The good new is for little mammals was that if you stayed off their paths you were fairly safe. There's a paleontology Ph.D. in this for someone.
I’m sure it’s obvious by the comments but to anyone new, “phorusrhacid” has a soft “c”. Also there is a pretty big error in the video at 3:30 where he suggests Gondwana existed at all in the cenozoic. South America separated from Gondwana in the Jurassic period. Possibly before birds evolved let alone phorusrhacids. This is why it is controversial that they made it to the other continents.
So we ALL agree that the name shall be forest rocket from now on
How interesting that the bite down method and weak bite forces of the terror birds is so similar to that of the method proposed for Allosaurus
I know it's essentially impossible. But I wonder if predatory terror birds somehow made it to Australia, would they have lasted far longer than terror birds in our own timeline did? Megalania and Terror Birds might have been enough to thwart human settlers and who knows, they could have been around until very recently. Great video nonetheless!
Unlikely to thwart humans. Big animals are all weak against humans. It's only very small creatures which can thwart humans (insects, bacteria, protists, etc)
Wood Elves in WW2: FORREST ROCKETS
Took me 6 minutes to realize he wasn't saying forest rockets. 🤣😂
Ah yes, the Forest Rockets episode. I keep coming back here every couple months
Though I enjoyed the presentation there was a couple of problems. Both Red-legged Seriema, a.k.a. Crested Cariama, (Cariama cristata) and Black-legged Seriema (Chunga burmeisteri) are capable of flying seriemas in the family of Cariamidae. The other is the species Titanis walleri was a flightless Phorusrhacid found in Florida and Texas where it lived from the early Pliocene to Pleistocene, possibly late Pleistocene. The Bathornithids which lived in North America from Eocene to Miocene were related to the extant seriemas.
i hope large predatory birds get to evolve again some time in the future
Or we could influence a animal to evolve into one
Examples of Convergent Evolution from clear across the terrestrial "family tree", like sabery hooky fangs (Terror Birds, Saber Tooth cats, Smilodons, Thylacosmilus) or constriction (some carnivorous plants & some snakes) or sticky gooey snares (carnivorous plants & spiders), suggests plausible patterns for any extra-terrestrial organisms out there
Nice video!
The strength of the biteforce doesn‘t directly gives a hint how „strong“ a bit will be. What matters is how sharp the teeth or the beak is. So it‘s force per area what makes a bite (or a grip) strong or weak! That‘s also the reason why carnivores have sharp teeth
Awesome!
Frankly a loss to the world that these things went extinct in the long run. Hope something similar evolves in the future.
I can see roadrunners, even chickens, repeating their evolution. But maybe the seriemas and secretary birds will beat them to it. The latter is already halfway there.
