This bird has an all white body. The head, neck, tail and wings are white. No neck ring. Bill light colored. No undertail bar. Pupil dark; outer iris ring dark red chestnut; inner iris ring greyish-blue. This bird is actually a "frosty white". "Frosty" is visible in that the undertail bar that normally appears in the normal white is absent. This absence of the tail bar & the eye coloration is visible evidence of "frosty".
When you pair this bird to any another color the "frosty" will be visible in a percentage of the young (frosty is a co-dominate gene).
