Terrorbirds (Aves Terror) are animals used by the gnomes as mounts. They are found on the west side of the Tree Gnome Stronghold. They are also involved in the Rag and Bone Man quest, though the type of terrorbird that drops the special bone for the quest are only the ones that don't have any gnomes mounted upon them. They award 34 Slayer experience when killed.
