What are some descriptive words about the bird in "The Raven"?

Some descriptive words about the bird in "The Raven" include grim, stern, ebony [black], ancient and ghastly. The bird is also described more than once as still and unmoving, standing without a feather fluttering. All of these words accumulate to paint a picture of a severe, forbidding and majestic bird. He almost seems to be a person: perhaps a bit like a rigid, unsmiling man with black hair. This is no chirping, twittering, friendly little songbird. The raven instead contains elements of the sublime, a style popular in the late 18th and early 19th centuries, and characterized by evoking emotions of mingled awe and terror. In the end, the raven, with its grim aspect, demonic eyes and the dark shadow it casts has an oppressive effect on the narrator.
