The call of the cassowary is the lowest frequency sound made by any bird and borders on infrasound. To appreciate the power of the sounds in this video, you’ll need decent speakers or headphones – speakers on a mobile device or laptop will not transmit these frequencies.

More of a non-vocal sound than a ‘call’, Southern Cassowaries create this vibrating, booming rumble from deep within. With head tilted down toward the ground, its whole body shudders as the sound is produced. When you hear this sound in real life, you 'feel' the sound as it vibrates through the air. It sounds more like a noise made by a large mammal than a bird.

00:00 - 00:19: Throaty vibrating growls at close range
00:26 - 00:33: Very deep booming sounds at distance
00:40 - 00:50: Variation of deep calls at distance
00:58 - 01:05: Deep calls at medium range

    that low rumble make me feel a deep sense of danger inside me
  • Imagine being lost in a forest and you start hearing that rumbling around you.

  • @gravy180rs
    The fact that this is potentially similar to what a T Rex may have really sounded like instead of roaring makes the T Rex even scarier imo.
  • Cassowaries give us the best insight into how dinosaurs sounded change my mind

    With good headphones with full dynamic sound I felt this in my bones. That is some deep bass
  • @ellytrabread
    the difference with and without earphones is astounding
  • As someone who’s absolutely obsessed with paleontology, I love listening to these giant land-dwelling birds with non-syrinx voice boxes like emus and cassowaries and imagining I’m in a Cretaceous rainforest surrounded by meandering theropods like tyrannosaurus lol
  • @ehhhhh596
    So this is what they call primal fear, holy shit I'm getting goosebumps
  • @gh0stroy
    That's not a bird thats a goddamn dinosaur
  • @AzazelsWings
    The rumble is about 23 hz, at the very edge of what humans can hear, if you can't hear it, play it a 2x speed it changes the pitch just enough you may hear it
  • this is basically what a t rex would have sounded like, maybe much lower
  • @kylerex4217
    Amazing, you know for so long I thought big birds like cassowaries screech, but it turns out the actually rumble.
  • @skycloud4802
    It's crime not listening to this with headphones. Sounds amazing.
  • @calemills699
    I experienced this in person one time and I can’t explain how otherworldly it felt. Legit felt like something was wrong in my bones and my rib cage was rattling! Then I thought it was some giant helicopter or something taking off in the distance until we realized it was the cassowary like 15ft from us at the zoo. UNREAL
  • @alexmadness19
    i love how cassowarys sound and are like modern dinosaurs, if you think about it this is probably how some dinosaurs sounded in the past. (also the cassowary looks like and takes the form of a gallimimus)

    If I Ever For Some Reason Hear This, I'm Climbing Up a Tree
