Marvel talks quite a bit!
caiques in general can learn to talk a lot but it's not very clear (like a 1-yr-old, you can really only understand them if you spend some time with them)
She says "hi" "wooo" "marvel" "goodbye" (according to my dad) "what a bird" and "what what what a bird!" (she does the last two in a deep gravely voice, I think she learned them from the Grey in her previous home)
She also laughs, makes kissy noises, honks, wolf whistles, and "whispers" (sounds like the breathy noise you make when you're trying to whistle but can't, she'll mimic me when I do it)
very very chatty and LOUD! sorta like a tiel or conure in that if she's awake she's chattering
She talks the most in the shower or when she's fighting the Evil Green Shirt (an old soccer jersey she's decided must die)
