throat, the skin is bare of feathers, warty, and whitish gray in colour. 

 Bill, legs, toes, and claws black; irides brown. The female is slightly 

 less in size than the male ; and her plumage is less brilliant. Young birds 

 resemble the adult ; but their plumage has little gloss, and the base of the 

 beak is feathered, probably until the spring moult, as in the Carrion-Crow, 

 from which they may always be distinguished by their more slender beak 

 and the different gloss of the plumage.
