In 'The Raven' by Edgar Allan Poe the speaker says 'Much I marveled this ungainly fowl to hear discourse so plainly' What does the speaker mean?

"Much I marvelled this ungainly fowl to hear discourse so plainly,

Though its answer little meaning - little relevancy bore;"

Ungainly fowl means awkward bird, and the narrator is astonished that the bird answered his question even if the answer had little meaning.
