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
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
Other people: "Terror Birds"
Me: *F O R E S T R O C K E T S*
Lmao
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.
this whole video i heard "forest rockets" instead of "phorusrhacins", which is admittedly just as intimidating as "terror birds"
Apparently you were NOT saying "forest rockets", but I'm glad I'm not the only one who heard that every single time
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.
the forest rocket is my favorite kind of goose
Closed Captions are great in this video. "Forest Rockets" "Back in the Maya Scene" "Kevin Ken" "Brawn Tallness" "Full grown Sorry Emma".... GOLD!
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 RUclips 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.

Have you seen the bird "sorry emma" by captions?
Everyone else: I thought you were saying "forest rockets"
Me: LOOK AT ALL THOSE CHICKENS
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.
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.
@@bkjeong4302 Definition of apex predator: a predator at the top of a food chain that is not preyed upon by any other animal
One of my favorite post-cretaceous extinct animal groups.
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
Before Angry birds..
There were terror birds
Maybe they were also angry .. hence .. the terror
Bird isis.
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 RUclips, 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.
Forest rocket, forest rocket, FOREST ROCKET!! FOREST ROCKET!!
It really is crazy how perfectly south america fits into the west coast of africa
Imagine being so badass that "Terror Bird" isn't even your coolest nickname.
I'm glad I'm not the only one who heard "forest rockets" instead of "phorusharcids"
8:19 I never understood that pic
Everyone saying “forest rocket” sound like a cool name but “terror bird” is metal as hell
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
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.
After the extinction of most theropods ... Theropods still dominate today.
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
Even the CC auto-generates "forest rockets" lol
Julio Lacerda is such a good paleo-artist. Beautiful work and I'm happy to see it featured on such a high quality channel.
One of my favorite paleo species. I cannot describe how much I love these videos and their ability to be so interesting and informative
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
The forrest rockets! A fitting name.
I somehow heard the name as "Forest Rocket" 🤣🤣
It looks like the algorithm has noticed your channel. Good to see your subscription count growing.
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.
Ah. "Phorusrachids,"
instead of "forest rockets." Got it. Lol
I actually googled forest rocket until I read the comments LOL
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 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
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!
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!
I'm sure you know this now but birds, all of them, *are* theropod dinosaurs.
I'm so glad I'm not the only one that was hearing "forest rockets" 🤣. These comments did not disappoint!
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...
Forest Rockets. I've watched this video a few times, cannot unhear it.
If it wasn't for the comment section I would have been that guy telling my friends about the " Forest Rockets" haha
All excellent stuff; prehistoric life is fascinating indeed.
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.
Gondwana hadn't existed for millions years by the time of the Cenozoic, Gondwana was a thing in the Jurassic.
lol even the auto translate captions heard it as forest rockets
Terror birds were my biggest ops when I played Ark
Man... 7 year old me wishes he had access to this awesome channel. 23 year old me is arguably just as happy tho
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!!!
Wood Elves in WW2: FORREST ROCKETS
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.
Forest rocket seems apt.
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
Had to watch this twice because I was giggling at the Forest Rockets.
Ranks up there with the best I saw on the subject - the extinction theorem helped.
Subbed.
They should really change the name of the animal category to "forrest rocket"
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
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...
Took me 6 minutes to realize he wasn't saying forest rockets. 🤣😂
although i also heard "forest rockets" i actually came here to complain about the phrase "they were known as".
I went to type something about forest rockets and realized that’s not what was being said lol
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 .
I'm no evolutionary biologist, but I know a bit about eagles and other modern raptors. The hooked beak/ spike at the end of the beak in modern birds is not for killing prey at all but is used as a utensil. After their prey is dead, they use their beak to tear off small manageable strips of meat that they can swallow, and they use the powerful crushing force of their claws and feat to kill prey. Could the terror birds have used their large beaks to do the same thing, but simply with larger chunks of meat?
Terror bird beaks are much more analogous with the jaws of some theropod dinosaurs (except minus teeth) than those of eagles.
So we ALL agree that the name shall be forest rocket from now on
Literally found this channel today, and with it my new addiction to these videos.
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 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.
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.
Just found your channel. Loved it instantly.
Thanks for watching
Terror birds will forever be Forest Rockets for 309,000 people
Weren’t Africa and South America already separated by the mid-Cretaceous?
Yes
this confused me as well
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)
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 really like the background music.
Ah yes, the Forest Rockets episode. I keep coming back here every couple months
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 .
The terror birds look delicious.
As do you to them.
NO!
No, Forest Rockets was their team mascot name. The Sao Paulo Forest Rockets were Premiership Champions for 1.5 million consecutive years. #Dynasty #GOAT
I can only imagine our ancestors happiness upon hunting, cooking and eating kilos and kilos of roasted terror bird
I, too, would like a forest rocket.
For the entire video I interpreted the birds as "forest rockets".
" Forest Rockets" makes for a dope rock band name! 😂
Two points: First, modern day Cariamidae are flighted, and there are no known cases of a flightless bird clade having a daughter taxon that regained flight. So, it would make more sense that some ancestral flighted Phorusrhacids would have been the ones to colonize Africa and North America, no?
Secondly, there was a land that had a bird as the apex predator until a little over a thousand years ago: New Zealand and it's Haast's Eagle. Granted, it was flighted, but it fits your definition, and it only was driven to extinction by the arrival of humans on the archipelago.
But other than those little quibbles, I wanted to tell you how much I appreciate your channel and its content!
Birds biggest issue is their crouching stance, If through natural selection their bony tails grows back, their stance will be balanced, making super theropod size possible again. An animal can NOT get that big without a column stance, crouching is not viable for that much mass.
Don't birds have hollow bones, even ones where the bones are more dense than the flying birds?
@@budmeister Penguins have solid bones to help them with boyancy.
Some birds have marrow in bones like mammals.
Most birds have hollow bones.
Regardless, this has nothing to do with my original statement. The issue with birds is that they all have a crouching stance because they all lack a large bony tail. Name me one massive animal with a crouching stance? NONE. Massive animals need a column like stance, it is more efficient. Even our stance is a lot more efficient than birds.
"while dinosaurs died out 65 million years ago, the theropod dinosaur niche was still being filled"
birds *ARE* THEROPOD DINOSAURS
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
Therapod dinosaurs still exist as birds! 🦅
