Moulting for a while now and Blueberry's once long tail (Blueberry colored at the ends hence the bird's name) is now down to a stubby 2- inch tail.
Moulting can be a very uncomfortable time and they can experience irritability, lack of energy, loss of appetite, and physical appearance can be compromised. This is just temporary and no need to worry when your bird(s) are going thru this which takes place several times a year.
Many think Blueberry's a girl. I believe Blueberry's a boy with a hormonal imbalance. Please see my videos in my playlist "Blueberry cere" and let me know afterwards what you think.
