What is an old Turkey called?

Excuse me, I'm curious about a particular term related to the poultry world. Could you please tell me, what is the colloquial name given to an older turkey? I've heard it referenced in conversation before, but I'm not quite sure what the proper terminology is. I'm interested in learning more about the terminology used to describe different stages of a turkey's life cycle, and this seems like an interesting factoid to add to my knowledge base. Thanks in advance for your help!
