I Think This Bird Might Be Lost

I was working in the kitchen this morning and saw this bird. The picture is not great, but I have never seen another bird like it since we have lived here. (So basically, I am claiming that this is Arizona's version of the Yetti.) Anyway- it has a bright yellow breast, greenish feathers and a really long tail. It looked almost like a parrot. I am wondering if someone's pet has escaped.
