LEBANON, OH -- Leucism is a genetic condition that appears in the animal world resulting in normal color patterns being disrupted and replaced with white skin, fur, scales or feathers. The affected area can appear in irregular patches or can cover the entire body of the animal. It is caused by a different recessive gene than the one that causes albinism. 

A notable difference between leucistic and albino animals is eye color. Leucisitic animals have dark eyes whereas pure albino animals have pink eyes. Leucistic or albino animals represent very small portions of their respective species.

Just recently I happened to encounter two species of birds that exhibited leucism. One was an American Robin in Armco Park.

 The other one was a Dark-eyed Junco that showed up under my backyard sunflower seed feeder.

Over the years I’ve encountered white squirrels in our area sometimes without being able to decide whether they were leucistic or albino since it’s hard to get close enough to them to be sure of their eye color.
