Raptor Harpies ( 猛禽種, Mōkin-shu ?) are large eagle- or hawk-like harpy subspecies.
Harpies are mono-gendered and rely on humans to reproduce.
Since all harpies hatch from eggs, there's a possibility that the clawed opposable digits served to help them crack the inside of their eggshells (pipping) when they hatch as harpies don't have beaks like traditional birds do.
This allows for gripping of objects, but these improvised grabbers are nowhere near as dexterous as true hands. Harpies have a clawed, opposable digit on the joint of each wing, and the wing at the joint has a "palm" which can curl to some small degree. However, due to their air-headed personalities they more often then not forget about their "rules" and just do what they please, with that rule being: "Harpies are not allowed to stay a long time in a place. Being similar in nature to migratory birds, Harpies psychologically can’t stay in one place for very long. Harpies are migratory beings and a race that embodies the notion of freedom, going where they please, when they please.
