Leucism, or leukism, is an abnormal plumage condition caused by a genetic mutation that prevents pigment, particularly melanin, from being properly deposited on a bird’s feathers. As a result, the birds do not have the normal, classic plumage colors listed in field guides, and instead the plumage have several color changes, including: white patches where the bird should not have any; paler overall plumage that looks faint, diluted or bleached; or overall white plumage with little or no color discernible.
Leucism is relatively unusual in birds, and albinism is rare. From 2000-2006, Project FeederWatch participants reported fewer than 1000 leucistic birds. Given that participants report about 5.5 million birds each season, the percentage of leucistic birds being reported is very small.
