Trail of Highways ™; What is a Leucistic Screech Owl?
Presentation is at Boyd Hill Nature Preserve, “Raptor Fest 2015”
Meaning of Leucism /ˈljuːsɪzəm/ is a condition in which there is partial loss of pigmentation in an animal resulting in white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes. Unlike albinism, it is caused by a reduction in multiple types of pigment, not just melanin.
