Are White Peacocks Albino? Leucism and Peafowl Colors

Leucism vs albinism

Both conditions make an animal look pale or white, but they work differently:

In leucistic animals, the problem lies with the pigment-producing cells. These cells normally travel to the skin and growing feathers early in the embryo’s development. In leucism many of them fail to arrive or to work, so the feathers are left without color, while the eyes, which get their pigment by a different route, stay dark. An albino animal, by contrast, has pigment cells everywhere but cannot make melanin in any of them.

Why are white peacocks white?

The white form of the Indian peafowl is inherited. It behaves as a recessive trait: a chick has to inherit the white gene from both parents to be white. Two white parents breed true and produce only white chicks, while a blue bird carrying a hidden copy of the gene can produce some white chicks when paired with another carrier.

White peachicks hatch pale yellow and become pure white as their feathers grow. White males grow a full train with the same structure as blue males, and the eyespot pattern shows only faintly as a ghostly outline.

A normal peacock’s blue and green shine is mostly structural color, made by tiny layered structures in the feathers that reflect light, combined with dark melanin underneath. Without that melanin, the structures still exist but the brilliant colors cannot appear, so the feathers look white.

Where do white peafowl come from?

White peafowl have been kept in Europe and Asia for centuries. Charles Darwin discussed peafowl color varieties, including white and black-shouldered birds, in his 1868 book on domesticated animals. In the wild, white birds are very rare. A white bird is more conspicuous to predators, and because the gene is recessive, a white chick only appears when two carriers happen to mate.

In captivity, however, breeders have selected white birds for generations, so white peafowl are now common in zoos, parks and estate gardens across Europe, North America and India. Some free-roaming park populations include white birds alongside blue ones.

Other peafowl colors

The normal wild coloring of the Indian peafowl is called “India blue.” Peafowl breeders recognize many other color and pattern forms, including:

• Pied: a patchy mix of white and normal colored feathers, caused by partial leucism.
• Black-shouldered (black-winged): males with dark wing coverts instead of barred ones; females and chicks are much paler than normal. Darwin used this form as evidence that a new variety could appear suddenly among captive birds.
• White-eyed: eyespots with a white center instead of the usual dark one.
• Color shades: breeder varieties such as cameo, purple, bronze, opal and charcoal.

Many of these forms can be combined, giving hundreds of recognized varieties among captive birds. All of them are the same species, Pavo cristatus. Peafowl also hybridize with the green peafowl in captivity; these hybrids are often called “Spalding” peafowl.

Are albino peacocks real?

True albino peafowl are very rare. They lack melanin completely, so their eyes look pale pink or red. Because almost every white peafowl people see in parks is leucistic, calling white peacocks “albino” is a common mistake.

Leucism shows up in many other animals too, from deer and squirrels to the pale captive forms described in What color are wild axolotls?

Can white peacocks survive in the wild?

White peafowl are healthy birds, and leucism does not usually cause the eyesight problems often linked to albinism. Their main disadvantage is visibility. A normal blue peacock or brown peahen blends surprisingly well into dappled forest shade, but a white bird stands out to leopards, jackals and birds of prey, especially on the ground at dawn and dusk.

A white peahen faces the biggest risk, because she sits on her eggs on the ground for about four weeks. Camouflage is her main protection, and white plumage removes it. This is one reason white birds stay rare in wild populations in India and Sri Lanka.

In parks and gardens, where large predators are absent, white peafowl live and breed as well as blue ones. Feral flocks in places such as California, Florida and New Zealand sometimes include white or pied birds descended from captive stock.

Do white peacocks still display?

Yes. White males court peahens exactly like blue males, fanning and shaking their trains at the display ground. Read more about the display in Why do peacocks spread their tails?
