Every once in a while in his cage, I will notice his tail bobbing, but it it isn't consistent. Maybe, 2 hours out of the day, max. But when he is out of his cage, sometimes he just sits quietly, scared to death, breathing fast, and tail bobbing. There are other times when he is happy on my shoulder and chirping, then the next day he suddenly becomes a different bird. Is this from excitement or fear? He is eating, drinking, not fluffed up, and sings, plays just fine. When I go to take him out of his cage, he is a little hesitant, but doesn't run away. I talk to him softly and he will get on my finger and let me take him out.
Should I be worried?
Also, he gets about 3-6 hours outside of his cage and I have had him for 1.5 weeks. He came from a pet store (I work at it and we take very good care of our birds) and was already finger trained. He has started bonding with me, as he won't stay with others (tries to fly back to me after getting on their finger).
What can I do to help him? TIA
