The Hoatzin is a bird from Ecuador. It is known locally as the 'smelly bird' or 'stink turkey' because of its strong unpleasant smell. It has never been a popular dish. Young birds actually have claws on their wings, as if this is an ancient species.Scientific Name -- Opisthocomidae hoazin
Hey theres a red bird at /creatures ;)
Well, your bird may not have access to bathing water, or it might have mites. You might want to take your bird to an AVIAN vet, because it might be sick, if it doesn't have mites/is dirty. Even if your bird has mites or is a little dirty, I'm sure your local avian vet can help it. c:
