Her/his name is Nike. I'm pretty sure she is a boy but my previous bird of 39 years who was likely also a boy was named Berta and was referred to as a girl. When I picked up Nike I decided the easiest thing for my brain was to continue to call my new bird a "her", so my girl Nike didn't get a new name upon the re-home but was now identified as a female....how contemporary is that?
Nike's nickname is Berta just because I cant get 39 years of calling that name out of my brain. I did consider changing her name but she uses it in a few of her learned phrases so I decided to keep it.
Here's a totally unrelated pic of her.
