Yellow faceYellow face budgies are in between yellow-based budgies and white-based budgies. There are different degrees of the level of yellow pigment, less than the yellow-based variety. These different levels of yellow pigment are caused by several different genes. Visually, there are two types of yellow face: Type I and Type II. In type I yellow face budgies, the mask feathers are all yellow. The yellow may also show up in the peripheral tail feathers. The yellow is confined to these areas only and the budgie is normally colored in the body feathers.
Type II yellow face budgies have yellow in the mask feathers and tail, just like the type I. However, after the first molt at 3 months of age, the yellow diffuses into the body color and creates a new color, depending on the original color. In the case of the sky blue variety, , the type II yellow face creates a sea foam green color, but in the type I yellow face the body color remains sky blue
