akane:I would say the last one is double factor dominant pied, cobalt, yellow face 2. Not sure about any opaline. The little patch of black wing markings at the top looks like what I've seen on many other df dominant pieds.
You may be right about her being a double factor. I posted a couple more pictures, you can see her back in one. Its not the best picture (shes very camera shy) but it may help with indentification! I do think shes an opaline though, her striping pattern is reversed so that her cream coloured bars are thicker then the black. Thanks for commenting!
Oh, and ignore her pink tail! She has a mineral perch! hehe!
And to everyone else thanks for complementing my birds! They'll all be very happy to hear your kind words!
