Bird No Colour
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.
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.

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. The blue wavelength is refracted, which is what allows us to see the feathers as blue in color, according to the Cornell Lab.
This optical illusion is not unique to blue jays. This same trick of the eye gives all blue-colored birds, including indigo buntings and bluebirds, their brightly colored appearance; none have any blue pigment. When is a blue bird not blue? The answer to this question is always.

There actually is no such thing as a blue bird. To find out why, Smithsonian asked Scott Sillett, a wildlife biologist at the Smithsonian Migratory Bird Center. "Red and yellow feathers get their color from actual pigments, called carotenoids, that are in the foods birds eat," Sillett explains.
"Blue is different―no. 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. 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. 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. 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.
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.
