Albinoism is common in Blackbirds, but there are even more that are "partially albino" or leucistic (e.g. white head, or white patches on the wings). Albinoism is usually a genetic condition that causes no pigment to be used, and feathers are made from keratin which is naturally whitish in colour. Albinoism can also be caused through malnutrition, parasites, or poor diet.
