An darkish and sinnery Stymphalian Bird, feathers drop as arrows as metal, beaks sharper as darken bronze, and the size of an Crane.

Randomly based of the bird's design of Bald Ibises in North, and while plus the appearance characteristics of the bird didn't mention what type of bird it was in the myth, so I just search it some by myself. Hell, the wiki of this Northern Ibise has a culture connection with Stymphalians like them.
