What is Leucism
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
Overall white plumage with little or no color discernable
