Hershey is usually very vocal in the mornings, not so much in the afternoon but gets very vocal in the evening. I think it's because thats when I am home. It's amazing how much they pick up in a short period of time.
In 2 weeks she says Hello, Pretty bird, Whatcha doin, and various whistels and other noises. She also sounds just like my Tiel at times. It's awsome just to sit and listen to her. She only has 1 high pitched screetch that makes my head hurt but dosent do it very often now that I dont respond to it.
