Dire corby

The Dire Corby is an ancient race more common to the southern reaches of the Underdark. Corbies are bipedal and black skinned, with a beaked bird's head, and the torso of a man, featherless and wingless. Both of its powerful-looking arms end in hooked, wicked claws, and its legs ending in three-toed feet. Belwar Dissengulp remarked that corbies look like a drow-bird crossbreed.
