Help confused about this birds mutation
I am still learning about mutations and I am confused about this birds mutation and would really like some help with it. I have attached photo although not showing the back of her very well (she wouldn't stay still long enough).
On her rump and around her vent she has what looks like either a mauve or cobalt blue, if you look closely at the picture you can see it around her vent and a little around her neck and near her leg. I have been told that she could be light green dom pied or olive green df dom pied. This has confused me even more as she has no green on her at all.
I am pretty sure she is dom pied as she has the spot on the back of her head but the rest who knows because I sure don't.
All help very much appreciated.
P.S Sorry about the photo being on the side I am still trying to work out how to edit pictures on new computer.
