Mistress Hinnygizzard was a shryke who Cade, Gart and Thorne encountered while on their way to Hive in Doombringer. Her roost was in a hidden clearing in the Western Woods. She had gaudily bright feathers and was taller than her companion, Sister Plume. She gave Cade a supply of offal after she became fascinated by Gart's red-lead pencil. Her shryke-mate was called Gwilp.
