Thanks！I purchased my birds from a pet store at different

times, so I believe their mothers raised them rather than humans who nurtured them since birth. As a result, they are naturally afraid of people. However, I have been able to tame my birds by letting them perch on my finger and shoulder. They learn quickly and do well, though they still maintain a certain distance. Tian Tian, the blue one, allows me to kiss him, and Niu Niu, the green one, doesn't like me touching her except to sit on my finger or shoulder.
