Appearance
The Yellowface I Skyblue variety is the same in appearance as a normal Skyblue except that the forehead and mask, which is white in the normal Skyblue, is replaced by bright yellow, the short tail feathers show yellow instead of the normal white, and the undulations on the wings are often faint yellow. The yellow on the mask tends to leak down onto the breast to a small degree, giving it a green tinge. In juvenile plumage the yellow is considerably fainter and does not appear on the forehead, which is barred in the usual way, nor does it leak onto the breast to as great an extent.
The Yellowface I Cobalt and Yellowface I Mauve varieties have similar yellow markings.
The appearance of birds with other combinations of the Yellowface I mutation is discussed under Genetics below.

Famous quotes containing the word appearance:
“Men of all professions affect such an air and appearance as to seem to be what they wish to be believed to be—so that one might say the whole world is made up of nothing but appearances.”
—François, Duc De La Rochefoucauld (1613–1680)
“Now the appearance of the glory of the LORD was like a devouring fire on the top of the mountain in the sight of the people of Israel.”

“The President has paid dear for his White House. It has commonly cost him all his peace, and the best of his manly attributes. To preserve for a short time so conspicuous an appearance before the world, he is content to eat dust before the real masters who stand erect behind the throne.”
—Ralph Waldo Emerson (1803–1882)
