This leucistic (piebald) common grackle was photographed at the Wichita Valley Airport by John McMurray. Although unusual, it does occur in all animals. Most notable in horses, crows, and ball pythons but is also found in many other species. In contrast to leucism is albinism, which always affects the entire animal. A further difference between albinism and leucism is in eye color. Due to the lack of melanin production in both the retinal pigmented epithelium and iris, true albinos typically have red eyes due to the underlying blood vessels showing through. Leucistic animals have normally colored eyes. That’s all today from your local one-eyed reporter! Phee Phew!
