L: Expanding Shanglanian human species! This reference is sloppy, because I tried to explain Grimm how exactly I see harpies aaaand somehow finished it.
Adult and old harpies are my favorite here. They still have a normal sanity, but if they are hungry, they attack people and even their friends of other species/subspecies.
So they are trying to live far from society, but still trying to be useful, hunting or slaying monsters.
