Double factor dominant Pied removes the pigment from select feathers on the budgies body (making them yellow or white) with up to 80% pied markings.
Pied Markings: There should be a pied patch on the back of the head. The primary flights up to the shoulders and tail feathers should have various pied markings, and often there is only a patch of color left on the rump. There should also be a large band of pied feathers around the lower belly area.
Cheek Patches: Depending on the pied effected feathers they can be normal (violet etc) or white.
Eye Color And Iris At Maturity: Black eyes with white iris.
Mature Adult Cere Color: If the pied markings effect the cere of the male it can be a mix of pink and blue, other wise it should be deep blue in males and light blue/white to tan in females depending on if
they are in breeding condition.
