I understand why you might think that, but that really doesn’t apply to a parrot and their noise.
Btw, an eclectus can (and probably will, regularly) emit sounds loud enough to make your ears ring. They’re meant to be heard over long distances outside in the open. Inside the walls of a home, it’s crazy loud.
Edit to add: They also make the noises when you’re not even home. It has nothing to do with treats.
I once had a great bond with an eclectus. It took a lot of work, but when I finally earned her trust, we were great friends.
One day, I trimmed her nails, and it destroyed our friendship 😔 If you get one, have someone else trim its nails so it doesn’t hate you. Parrots can really hold a grudge.
