Bird No Color
Birds with severe leucism have weaker feathers that wear out more swiftly than normal feathers. This makes flight more difficult, and eliminates some of the bird's insulation against harsh weather. Birds come in a stunning array of colours, from the bright red plumage of cardinals to the iridescent feathers of hummingbirds.
Yet, there is one particular bird that lacks any pigmentation at all: the albino bird. What is an albino bird? An albino bird is one that has a complete lack of melanin pigment in its feathers, eyes, skin, scales, or fur. Melanin is responsible for providing.

Birds With Imperfect Plumage Observe birds coming and going through a backyard long enough, and eventually you'll spot one that has partially white or all-white feathers where there should be color. These birds have a genetic condition known as leucism or, more rarely, albinism, which affects their coloring as well as their ability to survive in the wild. In fact, there are four rare genetic.
The color of the eye (iris) may be the most distinctive and diagnostic characteristic that distinguishes an albino from a leucistic bird. Albino birds have colorless eyes that look pink or reddish due to the blood vessels inside the eye. Birds' plumage can sometimes vary due to an excess, or a deficiency, of color pigment in some or all of the feathers.

Pigments are compounds that determine the color in birds' feathers. Albinism Albinism is a genetic abnormality that results in a complete lack of pigmentation in feathers, eyes, skin, and bill. The presence of white feathers on a normally dark bird is the most frequently seen color abnormality.
Every birder can expect to encounter white or partly-white birds with some regularity, and the more striking examples will stand out even to novices. In birds, leucism is not only limited to the color of a bird's feathers. There is a family of leucistic Trumpeter Swans that sometimes visit the Sanctuary.

Their legs and feet that stay yellow into adulthood are a dead giveaway that these birds have leucism! Leucism is also a heritable condition, meaning a bird with leucism may pass it down to their offspring! The next time you visit the W.K. Albino birds are completely white, and because they lack melanin in the retina as well, their eyes typically appear pink. Less commonly, some birds have a strikingly pale or patchy appearance, with eye color remaining normal, slightly lighter, or even blue, and this is called leucistic coloration.
Albinistic birds have pink eyes because without melanin in the body, the only color in the eyes comes from the blood vessels behind the eyes. It is possible for a bird to be completely white and still have melanin in the body, as when a white bird has dark eyes. But birds, like other animals, can also exhibit naturally occurring color and pigment variations that can make ID difficult.
For example: Albinism results from a genetic mutation that interferes with production of the pigment melanin. Unlike humans, animals without melanin may have other pigments, so they may still have some color.
