These are our babies. We adopted them from Petsmart 2 wks ago. The lt blue (my daughter's) is named Diamond. The dkr.blue is named Pretty Bird. I know, it's not original but he seems to like it. He responds better when I say it, and looks at me more when I say it. He will even chirp most of the time to it. So, he chose his own name. It was Pretty Boy but someone else in the forum said he might be a she?? Can anyone else tell. What about Diamond? he or she? Both of their ceres are lavendar or bluish but the nares have white rings around them. They are approx. 4-5 months old.
