A white buffalo or white bison is an American bison possessing white fur, and is considered sacred or spiritually significant in several Native Americanreligions; therefore, such buffalo are often visited for prayer and other religious rituals. The coats of buffalo are almost always brown and their skin a dark brown or black; however, white buffalo can result from one of several physical conditions:
They may be albinos, in which case they will remain unpigmented throughout their lives, and may also have hearing and vision problems.
They may be leucistic, with white fur but blue eyes, instead of the pink seen in albinos.
They may have a rare genetic condition which causes a buffalo to be born white, but to become brown within a year or two as it matures.
They may be beefalo, a bison–cattle crossbreed, and thus have inherited the white coloration from their cattle ancestry.
