He/she hasnt got a name yet as only arrived yesterday. I will try and get a oic of under wings if I can. She is a bit nippy though hahaWelcome to the site. We are glad you joined us. Love you took in a little lost one. I had a few myself and find that the rehomes are great pets for me.
About gender. On the blues it tends to take a under wing spread photo to be sure but from what I see right here I would think you got a boy. She is showing more of the bright blue in the wings than the girls typically show and more like the boys do.
What is his/her name?
