I just retagged post #1669439 from avian humanoid to winged humanoid but now that I think about it I'm not sure about that, and others like post #1669324, post #1669438, post #1669461, etc.
A winged humanoid has wings. That seems pretty simple. Usually this means an angel but it also applies to harpies who usually have bird legs. What defines an avian humanoid? A beak, like Medli? Feathers in other places? A tail? Looking through avian_humanoid a lot of them just look like winged humanoids to me.
