Wow. I used to think that the dinosaurs of old probably sounded like the typical bird of today, but this made me reconsider. This guy sounds much closer to a Jurassic Park dinosaur than to any other bird I've heard.
Jurassic Park is completely wrong about the Sounds. Dinosaurs were not able to "roar" like in these Movies. Moreover these "Monsters" in Jurassic Park are not supposed to be real Dinosaurs. Their genetic Code was altered and crafted. Imagine a deep rumble in the Case of e.g. Tyranosaurus rex. But so deep, you couldn't hear it, because our hearing can't hear past a specific frequency. But we may never know completely, since we literally just know fragments if these Animals. But since modern Birds are capable of a wide Range of sounds (Cassowarys can do more than this deep rumble), Dinosaurs could be too. But not this monster roaring.
Fun fact: there is an old saying about Cassowary meat that says that Cassowary meat is so tough that you put it into a pot with some rocks, and once the rocks become edible the meat is edible too.
Looks very similar to a cassowary I saw at an animal sanctuary near Cairns, Australia earlier this year when I visited. The enclosure looks quite similar as well. If it is the same one, she is still alive and doing very well!
The thing you’re not getting is the vibration. I don’t care what kind of headset or sound system you have- but if you don’t hear this irl you know NOTHING of what this is like. And I’m going off my experience with an Emu. I didn’t know that emus produced the sounds they made, but I felt it long before I figure out what was happening. The sound was so strangely specific that it was literally rattling my brain and disorienting me- I started getting dizzy. So taking that into consideration of a small bird, imagine what their larger ancient cousins could do. I wonder if they’d be able to kill someone just by being in close proximity of a “good morning, Fred.”
Now imagine the same thing but with a 10x larger resonance chamber and you've probably got the call of a predatory dinosaur. Just imagine something the size of your average garage making that kind of noise while staring at you because you accidentally entered its territory.
