"He always did himself well, Lucius. Peacocks . . . ”
-- Yaxley (DH1)
Also known as White peacocks, they are similar in size and behavior to Indian Blue peacocks.
- Real albino animals have pink or red eyes, but in peacocks the white color is caused by a different genetic mutation known as "leucism," so their eyes remain dark. To keep the colors pure they must be raised in captivity - or on a country estate, in the case of Malfoy Manor. Maybe the Malfoy family used a little magic as well. source: Wikipedia
