He got upset today, it is snowing here and the bird is from Arizona and opening and closing the door has caused drafts and he started squawking and he was cold so I put him upstairs because we lost power and were setting up the generator and the doors were getting opened a lot... So I brought him upstairs where it is nice and warm and he started cooing again and is happy he makes this funny sound when he is content that sounds like a frog...I love it!
