Hi everyone and thank you for you responses. Since I have recieved them I have been asking more questions (that I should have asked from the beginning!) I have had Buddy for about a month, but I have been acquainted to him for under a year. The previous owners had him for 2 years, and got him from other family members. Basically he has been passed around the family because no one has had the time or patience to care for him properly, and all were determined to see him go to a good home. I am determined to give that to Buddy!
I have continued to attempt to teach him to perch on my finger, but everytime I do he tries to get a scratch.
With time and trust allowed to grow, not forcing him, and reading I am learning more about his beautiful personality and his requirements for his species thanks to this website and the links you all have provided. It is greatly appreciated and very helpful.
