Have you ever seen a white Common Raven (Corvus corax)? No, this isn’t a new species… or a ghost. 👻 This Raven’s striking pale plumage is the result of the genetic mutations leucism or albinism. Leucism is a reduction in all types of pigmentation, including melanin. Albinism is the inability to produce or distribute melanin. One hint to tell the difference? Individuals affected by leucism often have blue eyes, while individuals with albinism have pink eyes. White Common Ravens are rare. An estimated 1 in 30,000 individuals is born without this species’ signature black plumage.
