While most birders depend upon plumage for bird identification, occasionally you run across an abnormally "marked" bird. Leucism can partially or fully effect an individual. It is simply a genetic defect that causes a lack of pigmentation. I discovered this male Northern Cardinal last year at Evergreen Lake. He still resides in the same area and has seemingly found a mate. I call him "Paleface" and check in on him regularly.
