SIZE of a Raven; length two feet, breadth four and a half; 

 weight three pounds. Bill nearly two inches long, and black, 

 much curved at the end, and covered, for three parts of its length, 

 with a kind of black cere, at the end of which the nostrils are placed,

 especially the forehead and chin ; the breast, belly, thighs, and vent, 

 pale dusky ferruginous ; legs black, rough, and warty ; claws, 

 especially the inner, very hooked, the hind toe very short, but the 

 claw crooked and sharp. The young bird is ash-coloured.*
