I peered through the glass.
It was a bird. At first I thought it was a crow because of its black feathers; they were so black they shone in the moonlight like a pair of sword blades. However, after looking at it keenly, I realized it wasn't. First, its beak wasn't that big. The beak of a crow was thick and long, as if it were an extension of its face. The beak of this bird, on the other hand, was almost as small as a needle. Also, unlike the angry eyes of a crow, this bird's were round and expressionless. They didn't convey any feeling—just pure, indifference void. The most noticeable feature, though, was a yellow spot on each wing. They looked like the rank badges that officials wear on their shoulders.
As you can see I repeat The X of the crow...and X of the bird twice.
Is the repetition above unnecessary? Should I use another phrasing instead?
