Yeah, there's gnawing, but that's different. And Fern takes snaps at me when she's Done With Petting, but those are just to let me know she's done, and she never actually connects. (Oddly, I got more tooth contact from the rabbit in the past. Little nips are how rabbits tell you to stop doing whatever is annoying them.)

Parrots do use their beaks to explore things, or to climb, but again, that's different from the serious BITES. She's learning, though.

She does chew holes in my shirts if I don't put something else there for her to chew, though. I think I'm stuck with that behavior. Chewing is just a parrot thing.
