Also the harpies gave me an idea for something.

Garudas, a subspecies of harpy that exists in the Tibet. They can be distinguished by their brown-golden plumage. They're more rapacious than their scavenger cousins, but they boast an intelligence on par with Dolphins. Fittingly, they seem to have the behaviour of the latter to help stranded humans. Or they're just tales and likely to attack humans. I mean, it's a pretty remote area...
