Harpies are creatures that are part bat and person and one of Jadis' Army. They only appear in the Disney version of the first film and never appear in Lewis' Workshop.
Film role and Extended version[]
During Aslan's sacrifice, Harpies were seen moving out of the way and they were seen in the crowd until they went to join the battle. During the First Battle of Beruna, when the gryphons and eagles from Aslan's Army were sent forth along to attack the White Witch's Army, by dropping rocks on them, many Harpies along with the vultures were sent to attack and try and stop them, though many were taken down in the process. One of them grabbed a gryphon and turned it upside down (when flying), which caused both of them to fall down to the ground and die. Another harpy spotted and tried to intercept the Phoenix that was assisting Aslan's Army, but before it could reach it, however, Peter managed to strike it down it with a spear that he had picked up from a dead Cyclops.
