The Jobberknoll is a small, blue speckled bird that never makes any noise until the moment before it dies. It then lets out a long scream, which consists of every sound it ever heard backwards. Jobberknoll feathers are used in Truth Serums and Memory Potions. Its main food supply is small insects and lives in northern Europe and America.
Behind the scenes
- According to Samuel Johnson, a jobberknoll is a loggerhead, a blockhead.
- The description of the jobberknoll — that it repeats everything it has ever heard before it dies — is perhaps a reference to the old myth that swans were supposed to sing a beautiful melody at the moment of their deaths, hence, "swan song."
