New sub. Great video. Great channel. Hope this channel blows up for you. it's going to become increasingly difficult to find good content that's not farmed AI content.

Calling them "the reptile bird" is like calling them the "bird bird" since *all birds* are reptiles‼️😂

16:30 about the captivity thing, Hoatzins are not known for doing very well in captivity due to their specific diet, and severe stress arriving from the wild. (If they don't die along the way) They do just as well as moorish idols. Which is they don't do well at all. Zoos have difficulty keeping them, and I think the longest that's lived in captivity was around 6 months. (although I could be corrected on that, as that's what I seen.) This was from what I researched about them in captivity, but feel free to correct me on anything I got wrong!

That's a good-looking dinosaur

It's a bird lol, there is still a bit of difference between birds and Dinosaurs. Not to mention that fully formed birds like owls and many other birds were found alongside those Dinosaurs. On top of that you can't say they have had millions of years anymore. Fossilized soft tissue protiens ruins that idea hands down. Evolution is pretty much a load of crap lol

Still just an avian dinosaur though

Very highly derived. I have been hoping since childhood the Hoatzin would be a stem bird.

All birds have a bird keel.

Most do. A few flightless ones have since lost it - e.g. the kakapo

Interesting. I, and many others I assume, are here because we're curious about this thing, how is it here, how did it evolve, why does its chick have those claws? etc. And from what I'm hearing the answer is a big old shrug. No one seems to have any idea.

Well, yes, birds do have "claws"! I mean, the last time I checked, they did… 😆 Unless of course you’re referring to the "talons" of the predatory owls or raptors, or the blunt "toenails" of the terrestrial ratites (ostriches, emus, rheas, etc). Lol. But I feel like hoatzin are weirder in other ways, though. They’ve evolved some very different adaptations, such as being able to digest leaves that are either toxic or that other animals avoid, in a manner similar to many primates, such as the proboscis monkey in Borneo… many leaf-eating primates have specialized gut bacteria/flora to ferment and break down toxic leaves, like Ficus (fig trees).

Claws on their wings. There was literally a picture too.

Is it red fleshed or melanistic? The blue skin reminds me of silkie chickens, they are black nightmares inside. Not sure if it relates (skin to organs).

@erikm8372 6 ай бұрын

The blue skin is simply around the eyes and cheeks. Similar to turkeys, or other birds like cassowaries, pheasants, or certain chickens that have various colors of skin. And sometimes the colors fade or get stronger based on the season or if it’s mating time 😉 aka "fired-up", how reptile breeders describe their animals’ brighter colors during certain periods.

Not sure the flesh color, as many native tribes in South America are said to actively avoid eating these birds, for various reasons ranging from the birds’ diets to the fact that they’re “possessed” or not “quite birds”. I’ve read a few accounts of people specifically NOT hunting them. Lol.
