They are very loud.Are they loud?
That depends on your pain threshold. Some people would find it hurts a lot more for them than other people. They do have very strong beaks.Do their bites hurt?
I’ll amend that. When they are outside the caiques scream for pure joy lol.My two are pretty quiet. They don’t scream but if they want something like lights to be turned off they will express their annoyance in isolated short squawks. My caiques scream though when they want breakfast and I’m late. Anyway in my experience screaming has always been associated with unmet needs.
