The male's tail is white, but the eyes of the tail are off-white in contrast. Not an albino, the eyes are light blue. The male is marked similarly to the blue male except he shows a purplish black shoulder instead of having the black and white checks. The hen is very unusually marked. She is mostly off-white with black and green flecking throughout the plumage.
Chicks hatch out yellow, but, unlike the whites, show some buff coloring in their flight feathers.
Black Shoulders are sexable at 4 months, when young males show black feathering coming through the lighter feathers. These are Black Shoulders combined with the Pied mutation. These are striking birds, showing most of the Black Shoulder coloring, but splashed with white. This is a fairly new mutation, about 20 years in existence. The male is all shades of brown and buff.
