Named Hugin and Munin, they serve as Odin’s eyes and ears. They’re first seen in Thor sitting on either side of Odin’s throne, and hovering over the king over his Odinsleep.

In The Dark World, one of the ravens is seen in Odin’s first appearance on his balcony. They show up again in The Avengers, when Thor takes Loki from the Quinjet, and they crash to the ground. The birds are later seen flying around as the brothers argue.
