Hi Billy and
to the forums!
Your new bird is definitely a female
She looks to be a light green, spangle budgie, although better pictures including shots of the wings would confirm that
By the darkness of her cere it's clear she's just coming into breeding condition, and by her lack of forehead bars she's definitely over six months old. I would say closer to a year, actually.
She's beautiful! Have you decided on a name for her yet?
I hope to see you around the forums and it's a great place to learn all you can about budgies
The many informative articles are sure to help you with your girl. Be sure to read the stickies, or the posts at the top of each subforum out there for easy reference. If you have any questions after reading them, be sure to ask!
I'm glad you've joined us!
