Cortez is Murdoc's raven. They met while Murdoc was in jail down in Mexico, but a raven with a very similar experience can be seen on Murdoc's stroller from when he was a child, which may indicate an earlier acquaintance of the two. Cortez's cawing can be heard in the track "O Green World". Cortez has jetblack feathers with bright red eyes. Murdoc often feeds him eyeballs, as depicted in the picture to the right.
