A pretty one, for sure! I'm not sure about the exact mutation, but unless it's a trick of the lighting, she looks to be a blue series. Maybe. Or experts should be along shortly. Whatever she is, Mamacita is beautiful!
I am so happy to see her in that large cage. :thumbsup:
IMHO, the dowel perches are okay. But it would be nice to add a Booda Comfy perch and a hanging swing. Bird-safe natural branches are good, too. Budgies need perches with varying sizes to exercise their feet.
Your bird needs a cuttlebone and/or ground oyster shell as a daily source of calcium.
